The Athletics made a pair of roster moves this morning, activating right-hander Brandon McCarthy from the 15-day disabled list while demoting first baseman Daric Barton to Triple-A Sacramento.
McCarthy hasn’t pitched since May 17 due to a strained right shoulder. The 28-year-old has battled shoulder problems at various points during his career, but he managed to make it back in the minimum 15 days and will start this afternoon against the Royals.
After reinventing himself last season while posting a surprising 3.32 ERA across 25 starts, McCarthy has an excellent 2.95 ERA and 40/16 K/BB ratio in nine starts this year. He has averaged just 1.61 BB/9 since the start of last season, which is fifth-lowest among starters with at least 200 innings pitched.
As for Barton, he has really struggled in his first season back from surgery to repair a torn labrum in right shoulder, batting just .198/.325/.283 with one homer and a .608 OPS in 126 plate appearances. The 26-year-old appeared to be a useful piece for the A’s after leading the American League in walks back in 2010, but he has a lousy .208/.325/.272 batting line since. Kila Ka’aihue will handle starting first base duties for now.
