Martinez hit .272 between AA Harrisburg and AAA Syracuse last season. He appears to be a right handed utility player. In 5 minor league season he has played all three outfield spots, all infield positions (except C and 1B) and even pitched in 2 games.

Just guessing but I’d say the only chance Michael Martinez has to stick with the Phillies is if he beats out Wilson Valdez.
I enjoy following a writer by the name of John Sickels who writes a minor league prospect book every year and his analysis of this pick by the Phillies was, “IF, from Nationals: 28 years old, hit .272/.312/.408 with 23 steals between Double-A and Triple-A. Good glove, some speed, but undersized at 5-9, 145, and has little upside given his age. I can’t say I understand this pick.”
