Akin was optioned to Triple-A Norfolk on Monday.
After giving up three earned runs over just a third of an inning Sunday, Akin will spend some time in the minors. He was in the middle of a career year -- recording a 3.40 ERA and 1.10 WHIP in 76.2 innings -- but he will be sent to Triple-A nonetheless. Logan Gillaspie will be promoted to replace Akin in the Orioles' bullpen.
