Who is he?
A non-prospect, called up late in the year to help the Tides finish out the season. Petersime was a late-round Orioles draft pick in 2009, and spent 2009, 2010, and 2011 in short-season leagues. Despite pitching consistently worse over the years, he survived 2012 spring training. After another stint in extended spring training and a holding appearance with Aberdeen, he was promoted to Low-A Delmarva where he pitched effectively in a low-leverage role. (Although he had five saves, most of them were of the three-inning, large-lead variety.) He was promoted to Norfolk in August to make an emergency start, and pitched well enough to stay with the team the rest of the season, even getting a non-emergency start.
Does he have a future?
Presumably, Petersime pitched well enough so that he won’t get released this offseason. Although he’s pitched in relief more and more over his career, it’s also generally true that he’s pitched worse the more he’s pitched as a relief pitcher. I think he ought to get a shot as a starting pitcher in High-A Frederick, but it’s also true that he’s a longshot prospect at best.
