I just saw this, I actually had no recollection of who Adrian Nieto was but I shall cheer for him my next Wahoos game
He was in Potomac, Low-A, a few years ago and got selected by the White Sox in the rule-5 draft. They were so desperate for catching that he actually stuck with the team for a year. Since then he's bounced back around the minors.
Devin Morasoco (current Red, not a former Nat). was there last week on a rehab assignment as well. I think he'll be there a few more weeks. He hit a go-ahead single with the bases loaded and two outs in the 8th at last Monday's game.
That is a beautiful ballpark.
