As was reported Saturday night, Mark Appel has been promoted to Double-A by the Astros. The 2013 number one overall pick in the June draft, it's not surprising that the 23-year-old Appel would get to Double-A just over a year since being selected. Given his pretty awful Class A numbers, though, it's surprising how he's gotten there.

Sunday, Appel threw a bullpen session in front of Astros personnel in Minute Maid Park and, apparently, the combination of the possibly-undeserved promotion along with the bullpen session didn't sit well with some Astros players.
