RHP Nathan Pettus (24)
Drafted out of community college in Oklahoma in the 27th round of the 2008 draft, Pettus sat out the bulk of 2010 and 2011 due to injury. In 2012, he pitched in 31 games (63 innings) for Lexington with a 5.86 ERA and a 1.714 WHIP. I'm not sure why, but his friends call him Carl.
