Jon Singleton was optioned to Triple-A Fresno today. Again. Let's recap Singleton's career to this point...
Singleton was picked by the Phillies in the 8th Round of the 2009 draft. I'm not going into the ins and outs of his early minor-league career, but he was highly-regarded as a prospect. After his first professional season, Baseball America had him at #39 on their prospect list while BP had him at #63.
He was traded on July 29, 2011 with Jarred Cosart, Domingo Santana, and Josh Zeid for Hunter Pence in what honestly seemed like a lop-sided trade.
