19-year old lefty starting pitcher Martin Perez came into this season as the Rangers’ #3 rated prospect according to Baseball America. He has started 14 games in AA-ball so far this season and he is 3-4 with a 5.19 ERA and a 1.63 WHIP. Perez has whiffed 63 batters in 59 innings this season but he has also walked 34 batters and that is way too many. Perez has now pitched in 56 games (48 starts) in his three years in the minors and he is 10-14 with 1 save, a 3.67 ERA and a 1.44 WHIP. The Rangers really like Perez but they could use him as a trade chip this month to get whatever they think they will need to win the A.L. West.
