Sean Doolittle struck out two over a scoreless ninth inning to earn his first save of the season Sunday against the Mariners. It was just Doolittle's fourth save of his career. The left-hander is part of A's manager Bob Melvin's bullpen-by-committee following Jim Johnson's struggles, so it may not be his last save this year. Still, unless he's explicitly named by Melvin he's likely not a rosterable source of saves.
