Dbacks deadline block

[DBacks]

Darren O'Day - 136 ERA+ reliever, rehabbing for September return, 2 rehab appearances without allowing a baserunner so far.
Anthony DeSclafani - good 4th/5th starter, 4.27 ERA this year in a hitters park with over a strikeout an inning.
Tim Locastro - you laugh, but he can play almost any position decently, has an above-average OBP, and Ex/Vg/Vg speed/steal/jump. Great 25th man for postseason roster.

Also, would be willing to deal a pitching prospect for an equivalent catcher or 1b prospect just to balance my team out a bit.
