The Oakland Athletics placed starting shortstop Marcus Semien on the 10-day disabled list with a bruised right wrist Sunday.
Semien has been bothered by soreness in his wrist since spring training and underwent an MRI scan Saturday.
He's scheduled to have a CT scan on Monday to determine if there's any further damage.
The move is retroactive to Saturday. It's Semien's first stint on the DL in his career.
