Athletics’ Marcus Semien out six weeks after wrist surgery

Athletics shortstop Marcus Semien will undergo wrist surgery to repair a fractured scaphoid bone, according to a team announcement. While an exact timetable for return is not yet known, Semien will be re-evaluated in six weeks and will be on the shelf until at least then.

Semien, 26, has been dealing with wrist issues since spring training but did not receive a definitive diagnosis until Monday. He is only 6-for-35 with two extra base hits so far this season, meaning his offense has clearly been effected by the nagging wrist.

Oakland will employ free-agent signee Adam Rosales and 25-year old Chad Pinder at the position in Semien’s absence, but do not appear to be considering promoting top prospect Franklin Barreto at this time. The club also has Matt Chapman at an option at Triple-A if Rosales and Pinder do not produce.

Semien hit just .238 with the A’s last year, but hit 27 homers in 159 games in his second season as the club’s primary shortstop.
