It says active.
Z sent an email to the River Cats asking about Puello, because he stopped playing in mid-August. They said:
Looking through things, it does appear he was placed on the DL: http://www.milb.com/milb/stats/stats.js ... 2&sid=t105Puello was placed on the disabled list on August 18 with a minor injury, and our season ended on September 3. We do not disclose specifics of injuries I'm afraid. I hope that was at least a little helpful.
I'm a little conflicted since his player page says active. I'm not sure what Bren is/was supposed to do in this instance, to be honest. How was Bren supposed to know to bench him?
The fact that this information wasn't produced with an internet search, but rather emailing a team then going through a transactions list makes me believe he was ok to play. That's a pretty crazy level of research to go to, and a pretty unfair threshold.
