Hayden Birdsong threw five sharp innings in his first start of the season and the San Francisco Giants beat the Kansas City Royals 3-2 on Tuesday night. Birdsong (2-0) was moved from the bullpen to the rotation in place of Jordan Hicks and provided just what manager Bob Melvin hoped he would deliver when he made the move. Birdsong allowed one unearned run, five hits and no walks to give the Giants their fourth win in the last five games.
