Semien had two more hits on Sunday to raise his average to .314, but he also committed two more errors to raise his Major League-leading total to 13. Semien has been great at the plate to start 2015, but the fielding issues are starting to become a black eye for him. He is the every day shortstop for the A's at the moment, but he will need to get the defense in line if he is going to stick there all season.
