The Orioles have placed righty starting pitcher Koji Uehara on the 15-day disabled list with a sore hamstring. Uehara has started 9 games this season for the Orioles and he is 2-3 with a 4.09 ERA and a 1.40 WHIP. The Orioles have recalled their #16 rated prospect heading into this season according to Baseball America….right hander David Hernandez who will replace Uehara in the rotation. The 24-year Hernandez has started 8 games in AAA-ball this season and he is 3-1 with a 2.91 ERA and a 1.06 WHIP. He has whiffed 60 batters while only allowing 33 hits in 43 1/3 innings in the minors this year. It’s about time that the Orioles let some of the kids get a chance to show what they can do. They should have done this from the start of the season instead of going with stiffs like Adam Eaton and Mark Hendrickson in the starting rotation.
