Athletics shortstop Marcus Semien is 4 for 10 against lefties over the first two weeks while hitting just .211/.250/.368 against right-handers.
Semien has struggled with the bat over the last week, going just 2 for 17, but he could be in for a boost during the upcoming week. He'll match up with three southpaws over a four-game span starting Tuesday. Semien also delivered an OPS 98 points higher against lefties in 2014, so any string of left-handed matchups could indicate an impending boost in production.
