LHP Brett Oberholtzer (23)
Originally drafted by Atlanta in the eighth round in 2008 out of Seminole Community College, Oberholtzer came into the Astros organization as part of the July 2011 Michael Bourn trade. In 16 starts this season, he is 6-4 with a 4.85 ERA and a 1.407 WHIP. But those numbers are somewhat misleading as Oberholtzer had a fantastic stretch at Corpus Christi immediately prior to his promotion to Oklahoma City. In his last six starts at Corpus, he was 4-1 with a 2.15 ERA and a 1.221 WHIP.
