Orioles Prospect Report - December 2025

[Orioles]

From BP's December 1 article 2026 Prospects: Sacramento Athletics Top Prospects:


1. Leo De Vries

Pos: SS
Born: 2006-10-11
B: Switch
T: Right
H: 6′ 1″
W: 183 lbs.
History: Signed January 15th, 2024 by the San Diego Padres out of the Dominican Republic for $4.2 million. Acquired from San Diego for Mason Miller and JP Sears.
Previous Rank: #1 (org, SDP), #23 (Top 101)
Major-league ETA: 2027

The Report: One of the top names from the 2024 IFA class, De Vries has done nothing but boost his stock higher over the past two years. After heading right to full-season ball in 2024, he more than held his own in the Cal League, posting major-league quality exit velos with impressive contact ability considering his age and level. His age-18 season was more of the same, ending in the Texas League, where he slugged .551 over 103 PA. De Vries is incredibly advanced for an 18-year-old switch hitter. His swings mirror each other well, with the right-handed swing having a bit more twisty, torquey, upper-body action, while his lefty stroke is more brute force and bat speed. He was better from the left side this year, but hit more as a righty in 2024. I don’t think De Vries will end up with much of a split long-term, but I do think the left-handed swing is more of a finished product at present, not uncommon for a young switch-hitter getting more reps from that side. Despite the bat speed and occasional violence in the swing, he moves the barrel around well, and is very comfortable swatting a single rather than trying to fully sell out for his power. The power should round out to plus-plus in time—he already hits a lot of flyballs given his age and level of competition—and De Vries might end up with the best overall offensive tools of any prospect in baseball. If we were more certain he’d end up a major-league shortstop, he’d have a strong case for the number one prospect in baseball. As it is, we think it’s more likely he slides to second or third base long-term, and thus is merely one of the five best prospects in baseball. Oh well.

OFP: 70 / All-star infielder

Variance: Medium. I guess this is the spot where we nitpick a little. De Vries was merely okay before the trade, and his performance in the Athletics org is only a fraction of one season as good as it is. He may settle in as more of a plus regular if the raw power doesn’t take another step forward, and he’s already mostly filled out his 6-foot-1 frame. Of course if this is just what he is, he’s probably ending up a plus regular, which is why the variance is this low for a still-teenaged prospect.

From BP's December 3 article, 2026 Prospects: Miami Marlins Top Prospects:


3. Robby Snelling

Pos: LHP
Born: 2003-12-19
B: Right
T: Left
H: 6′ 3″
W: 210 lbs.
History: Drafted by the San Diego Padres 39th overall in the 2022 draft, Robert McQueen HS (Reno, NV); signed for $3 million. Acquired from the Padres for Tanner ScottandBryan Hoeing
Previous Ranking(s): #7 (org)
Major-league ETA: 2026

The Report: Snelling has yo-yoed back into Top 101 consideration after a rough 2024 campaign in Double-A. He’s added a couple ticks to his fastball and now sits 95 and tops out at 98. Like with White, the pitch isn’t a metric monster—although it has solid enough carry from a sub-6-foot release height—but this kind of velocity from the left side is going to miss enough bats, especially when Snelling’s plus curveball is lurking in the minds of opposing hitters. It can reach the mid-80s with big two-plane break, and should rack up strikeouts in the majors. Snelling sprinkles in an average, if firm, change and a below-average gyro slider, but both are fine enough as supplementary pieces. You are here for the top two pitches on the marquee, though, and with the added velocity and improved command, Snelling once again looks like a precocious, quick-moving mid-rotation starter.

OFP: 55 / no. 3/4 starter

Variance: Medium. Snelling’s velocity and command have been inconsistent throughout his time in the pros, and while he should be in the bigs before long, he’ll need to maintain his 2025 gains to secure a rotation spot in what will be a crowded 2026 Marlins pitching picture.

From BA's Chicago White Sox Top 10 Prospects in 2026:


2. Caleb Bonemer, SS

Ht: 6'1" | Wt: 195 | B-T: R-R

Age: 20

BA Grade/Risk: 60/High

Adjusted Grade: 50

Track Record: Bonemer was a showcase star in the summer before his senior year at Okemos High in Michigan, with the White Sox drafting him in the second round in 2024. He broke camp with Low-A Kannapolis in 2025 and exceeded even the highest expectations. He batted .281/.400/.458 with 10 home runs and 27 stolen bases in 96 games to earn Carolina League player of the year honors before finishing the year with 11 games for High-A Winston-Salem.

Scouting Report: Bonemer has an advanced approach at the plate, especially impressive for a teenager. He’s made swing adjustments since turning pro, flattening his plane and improving his rhythm, which has helped him make better contact. Bonemer connects on pitches in the zone and has a knack for finding the barrel with above-average bat speed. He should get to plus power at his peak. At times, Bonemer has inconsistent separation in his load but has shown the aptitude for continuous improvement. Questions remain as to his ultimate position. He likely will not stay at shortstop, especially with 2025 first-round pick Billy Carlson coming up behind him. Bonemer can be an average defender at third base, where he spent some time late in the season. He makes the routine plays, and his average arm will be enough for the position, but some observers believe he eventually could wind up in the outfield. An average runner, Bonemer stole 29 bases in 37 attempts, but he may slow down to fringe-average as he matures physically.

The Future: While Bonemer faces questions as to his ultimate position on the field, his bat is real and profiles him as a potential above-average regular. He’ll return to High-A Winston-Salem in 2026 and has a chance to reach the upper minors later in the season.

From BP's 2026 Prospects: Chicago White Sox Top Prospects:


1. Caleb Bonemer

Pos: SS
Born: 2005-10-05
B: Right
T: Right
H: 6′ 1″
W: 195 lbs.
History: Drafted in the second round of the 2024 draft, Okemos HS (Okemos, MI); signed for $3 million
Previous Ranking(s): #8 (org)
Major-league ETA: 2028

The Report: Bonemer had a great 2025 on the field, rising from an intriguing but not necessarily exciting prep bat to a prospect pushing elite status globally. He has become a fairly easy scout, actually–-he hits the ball very hard, pulls the ball very frequently, and has excellent command of the zone. 20+ homers and a strong OBP is well within reach. His swing can look a little stiff coming out of a quiet stance with sparse lower-body movement, but visually the bat-to-ball fluidity within the zone looked improved later on in the season, and because he rarely chases the in-zone contact will be a primary metric to watch moving forward. He may also look to nudge the fly ball rate up a bit, but overall this was an exciting debut for an age-19 player, and he backed it up following a late-August promotion to Winston-Salem. Bonemer is a stout man (the pop has to come from somewhere), and he always looked like a player who would eventually move off of shortstop. He played third base almost exclusively with the Dash, and he has the hands, action, and arm to handle the position.

OFP: 60 / First-division regular, more likely at third base.
Variance: Medium. There is still some hit tool risk present, and he’ll need to unlock all of his pop to reach the plus regular ceiling. —Ben Spanier

From BA's Los Angeles Angels Top 10 Prospects in 2026:


6. Joswa Lugo, SS

Ht: 6'3" | Wt: 187 | B-T: R-R

Age: 18

BA Grade/Risk: 55/Extreme

Adjusted Grade: 35

Track Record: The younger brother of Dawel Lugo, who played parts of three seasons with the Tigers from 2018 to 2020, Joswa signed with the Angels for $2.3 million as the headliner of their 2024 international class. He received the second-largest bonus ever given to an international amateur by the club, trailing only Roberto Baldoquin’s $8 million in 2024. Lugo showed his offensive upside in his 2024 pro debut in the Dominican Summer League, hitting .301 with an .836 OPS and helping lead his club to the DSL championship. In his 2025 stateside debut, he produced a .271/.375/.372 slash line in 35 games before his season was halted with a back strain.

Scouting Report: Lugo is a physical, righthanded-hitting infielder with exceptional power upside. Balanced and synced through his swing, he handles the barrel well and displays plus raw power and elite exit velocities—north of 112 mph—that portend above-average power because of his high-end bat speed and barrel control. Lugo will have to overhaul his pitch recognition and exercise swing restraint. He too often gets in swing mode, which leads to weak contact and concerning swing-and-miss, particularly on secondaries. If he can refine his aggression, he has a solid all-fields contact and power baseline befitting of a middle-of-the-order hitter. Defensively, Lugo has good body control and instincts with an above-average arm that should keep him on the left side of the infield. Physical gains to his 6-foot-3 frame may slow down his middling speed and athleticism, moving him off shortstop and to third base.

The Future: Lugo has middle-of-the-order upside but will have to improve his pitch selection to become an impact power hitter. The extent of his physical maturation will dictate his future defensive home. He will get his first taste of playing at a full-season affiliate in 2026.

From BA's Athletics Top 10 Prospects in 2026:



1. Leodalis De Vries, SS

Ht: 6'2" | Wt: 183 | B-T: S-R

Age: 19

BA Grade/Risk: 65/Average

Adjusted Grade: 55

The Future: A native of the Dominican Republic, De Vries grew up idolizing Manny Machado and Fernando Tatis Jr., and for a time looked destined to join them in San Diego. The Padres signed De Vries for $4.2 million, the second-largest bonus in the 2024 international class, and aggressively pushed him to Low-A for his pro debut. In 2025, he was the youngest player to open in the High-A Midwest League at 18. His season took a shocking turn at the trade deadline when the Athletics acquired him as the centerpiece of the Mason Miller deal. De Vries was promoted to Double-A Midland soon after and finished the year hitting .255/.355/.451 with 15 homers across two levels.

Scouting Report: De Vries is already one of the most polished teenage hitters in the minors, showing preternatural bat-to-ball skills, a mature all-fields approach and a knack for loud contact even without elite strength or exit velocities. His track record and advanced skills make it easy to forget he won’t turn 20 until October. A switch-hitter, his lefthanded swing is more fluid and naturally geared for loft, producing line drives with carry, while his righthanded stroke remains less consistent and often pull-oriented. He’s still learning to rein in his eagerness. He’ll chase elevated fastballs and expand early in counts, but his hand-eye coordination allows him to get away with mistakes that would punish most hitters his age, and he rarely misses pitches over the heart of the plate. De Vries posted nearly identical exit velocities to 2024 and evaluators are split on his future power. Some see plus impact emerging as his body fills out, while others project solid-average pop that will play up through contact quality and timing. Defensively, De Vries shows the ingredients to stay at shortstop. He’s smooth, instinctive and confident, with soft hands and a plus arm, though his footwork and pre-pitch positioning still require refinement. At times, he can rush routine plays or get showy, leading to unnecessary errors. The A’s believe this can be cleaned up, and he has all the tools to become an above-average defender if he doesn’t outgrow the position. De Vries can turn in above-average run times underway, though he doesn’t always show it, and has good instincts on the bases. Evaluators were universally impressed by his innate feel for the game.

The Future: De Vries has one of the highest ceilings of any prospect in baseball, evoking comparisons to Francisco Lindor for his switch-hitting ability and two-way impact. His offensive profile will hinge on how much power comes as he matures, but he has all-star potential with a knack for maximizing his best-struck contact once he cleans up the finer points of his game. De Vries should return to Double-A to begin 2026, but the A’s aren’t afraid to push prospects aggressively.

Scouting Grades Hit: 60 | Power: 55 | Run: 50 | Field: 55 | Arm: 60.


6. Henry Bolte, OF

Ht: 6'3" | Wt: 195 | B-T: R-R

Age: 22

BA Grade/Risk: 55/High

Adjusted Grade: 40

Track Record: Bolte has steadily climbed the rungs of the Athletics’ minor league system since signing out of a Bay Area high school for $2 million as a second-rounder in 2022. Along the way, he made a series of mechanical tweaks in search of more contact. He split his age-21 season in 2025 between Double-A and Triple-A, batting .284/.385/.427 with nine home runs and 44 stolen bases over 114 games before a nagging wrist injury ended his year and required September surgery.

Scouting Report: Bolte is a player of extremes. He produces some of the best exit velocities of any A’s minor leaguer, runs the bases as well as any player in the system and is a potential plus outfield defender. Bolte has been quite productive in the minors and, on the right weeks, scouts see massive upside. In other weeks, they wonder if he’ll ever hit enough to piece it all together in the majors. The righthanded-hitting Bolte has smoothed out his swing and improved pitch recognition to trim his strikeout rates, yet still ran a 33% whiff rate in 2025 with holes up in the zone against velocity and down and away versus breaking balls. He also pounds too many balls into the ground, and his 59% groundball rate limits his in-game impact, though the A’s believe his lingering wrist woes contributed to that result. Bolte oozes athleticism on the bases and at all three outfield spots, and his frenetic play style can also lead to some erraticism.

The Future: There’s boom-or-bust risk with Bolte, whose power-speed profile is not far off from current A’s outfielder Colby Thomas. The organization remains encouraged by Bolte’s intangibles and year-over-year progress, and he has the upside of an everyday outfielder who hits .240 with 25-30 homers and steals bases—if he can find a way to optimize his swing and approach to make better contact.

From BP's 2026 Prospects: Los Angeles Angels Top Prospects:


3. Joswa Lugo

Pos: SS
Born: 2007-01-24
B: Right
T: Right
H: 6′ 3″
W: 187 lbs.
History: Signed January 15th 2024 out of the Dominican Republic for $2.3 million.
Previous Ranking(s): #7 (org)
Major-league ETA: 2029

The Report: While they’ve targeted mostly fast-moving college prospects with their top draft picks, the Angels do take bigger swings in the IFA market. Usually that’s been on toolsy up-the-middle prospects that can’t hit, but Lugo…might be able to hit. His numbers aren’t that impressive given the launching pad parks of the Arizona Complex League, and if anything, Lugo tamed his approach too much, going from highly aggressive in the DSL to downright passive in the Phoenix metroplex. When he does swing, it’s a quick bat that makes very very hard contact for an 18-year-old. I expect he will swing and miss more as he swings more—and he’ll have to swing more at some point—and his contact rate is merely fine for short-season ball. He also needs to hit the ball in the air more to really take advantage of the juice in his bat. But Lugo has even more room to add strength to his frame without moving off shortstop, and I would not be surprised if he easily tops this list going into 2027.

OFP: 55 / Above-average shortstop
Variance: Extreme. As good as the exit velocities are, Lugo slugged well under .400 in the desert, and the hit tool remains risky on top of that.

From BP's 2026 Prospects: San Francisco Giants Top Prospects:


9. Keyner Martinez

Pos: RHP
Born: 2004-08-16
B: Right
T: Right
H: 6′ 1″
W: 165 lbs.
History: Signed July 3, 2023, out of Venezuela for $10,000.
Previous Ranking(s): N/A
Major-league ETA: 2028

The Report: Martinez was a late-inning reliever on the complex in 2024 and early 2025, but the Giants began to stretch him out to start in early June and he went on an absolutely dominant run over his final eight starts, including allowing just one run in five innings in the complex league semi-finals. Martinez was among the cadre of ACL players promoted to Low-A for the Cal League’s final month and the San Jose Giants’ championship run, where he again impressed among a half-dozen appearances. Martinez already has two plus pitches in his mid-90s fastball and two-plane slider, and pounds the zone with both pitches, particularly to his glove side. While fellow ACL and San Jose teammates Argenis Cayama and Luis De La Torre share some uncertainty regarding how their bodies will hold up to a full season’s workload, Martinez is already a sturdy and physical presence on the bump and, like Jacob Bresnahan, looks like a future innings eater. Martinez’s changeup lags behind his two primary weapons, but it generally serves its purpose to keep left-handed hitters off his fastball. He’s likely to anchor the San Jose staff to start 2026, but it wouldn’t be a surprise to see Martinez get the bump to High-A Eugene by mid-season if he continues performing the way he did in 2025.

OFP: 50 / workhorse starter or back-end reliever
Variance: High. Martinez’s age gives him a bit more surety than someone like Cayama, but he’s still a pitcher in A-ball.

From BP's 2026 Prospects: Atlanta Braves Top Prospects:


3. Cam Caminiti

Pos: LHP
Born: 2006-08-08
B: Left
T: Left
H: 6′ 2″
W: 195 lbs.
History: Drafted in the first round of the 2024 Draft, Saguaro HS (Scottsdale, AZ) signed for $3,553,800.
Previous Ranking(s): #2 (org)
Major-league ETA: 2028

The Report: Caminiti was the first prep arm off the board in the 2024 draft. And while it was not a deep prep pitching class—or pitching class generally—he mostly lived up to that superlative in 2025. After spending May in the complex, Caminiti spent the rest of the season in Low-A, dominating Carolina League hitters with his fastball/sweeper combo. The heater sits in the mid-90s and overwhelmed A-ball hitters, mostly with pure velocity. There was previous concern about Caminiti finding a viable breaking ball, as he was more of a fastball/change arm as an amateur, but he now has a hand of god-type sweeper in the low-to-mid-80s that he can throw to either lefties or righties. His mid-80s change is more a third pitch now, but it still flashes above-average when he gets it gloveside and down to righties. Caminiti didn’t turn 19 until near the end of the season, and he’s going to have a long lead time to the majors, but the rapid development of his breaking ball is a positive marker, and he profiles as a plus fastball/plus breaker, mid-rotation southpaw.

OFP: 55 / no. 3/4 starter
Variance: High. Caminiti had a very strong season, but that comes with the usual teenaged pitcher, low minors caveats. He threw four-ish innings per start—and didn’t always hold the top end velocity deeper in those. He needs to continue to improve his secondaries and his command—the latter at times negatively impacted by a bit of a crossbody delivery.

From the MLB.com Pipeline article These 5 prospects improved their stock the most in 2025:


Caleb Bonemer

Started 2025: CWS No. 11
Finished 2025: CWS No. 4/MLB No. 73

Callis: Up and down high school career, in terms of the showcase circuit. If you saw him at his best, he looked really good. And if you saw him when he wasn’t playing well, he did not look really good. I thought he was inconsistent, I didn’t think he was a shortstop. The White Sox gave him $3 million, minus the $2,500 accounting trick, as a second-round pick in 2024. So, I was like, OK, this is interesting. And he was tremendous this year. He was MVP in the Carolina League, hit .283, had an OPS of almost .900 with 12 homers, made two Class A stops in his first full year in pro ball. And, even more so, his defense at shortstop was better than realized. Looks like he can play shortstop. Now, I don’t know if Caleb Bonemer will actually play shortstop in Chicago, but he’s capable of it, and he’s a guy who’s a better hitter and a better defender than I personally realized. So, my apologies to Caleb Bonemer for not being as bullish on him as I perhaps should have been.
