The A's claimed Lyman, a 23-year-old right-hander, off of waivers from the Braves in July. The 2005 second rounder struggled with control in Oakland's system, as he has throughout his minor league career. Lyman posted a 3.32 ERA last year, but in 2010, his ERA ballooned to 6.50 in 63.2 innings. Though he has started occasionally, Lyman is mostly a reliever. This year he posted 7.4 K/9 and 5.4 BB/9 at three stops in the upper minors.
