Gentry is not in the lineup for Friday's game against the Royals, MLB.com's Jane Lee reports. The A's will start Mark Canha in left field, with Ike Davis at first base and Billy Butler serving as the DH. The more offensive-minded lineup is Oakland's new preference against right-handed pitching, as Gentry hasn't gotten a start since Saturday, which was the last time the A's faced a southpaw. While his defense and baserunning have always been highly regarded, Gentry's splits make it clear that he's best suited to this kind of platoon role.
