With a captip to Farmstros, it looks as though the Astros have acquired Oakland minor-leaguer Mickey Storey.
Storey is a 6'2", 185lb RHP, drafted by the A's in the 31st Round of the 2008 draft (a year after being drafted in the 22nd Round by the Twins).
In four seasons - all as a reliever (except for one start in 2010) - he has posted a 3.04 ERA/1.08 WHIP, with 7.3 H/9, 2.5 BB/9, and 9.3 BB9, with a 3.74 K:BB ratio.
In 27 games for Double-A Midland, Storey posted a 4.03 ERA/1.42 WHIP with career worsts in all of the preceding statistics: 38IP, 41H/17ER, 31K:13BB.
