PHOENIX -- Like A's manager Bob Melvin hinted at Saturday, second baseman Jemile Weeks was not in the lineup Sunday against the D-backs and instead will be sent to Oakland's Minor League camp Monday to face live pitching and rehab from the bruised right shoulder he injured March 1.
"We want to get him some at-bats in a little bit of a more controlled environment," Melvin said. "It's a little easier for him to get at-bats there to make sure he's healthy. Once we feel like he's there, we'll get him back out here."
The club originally planned for Weeks to return Sunday, but the A's want to wait until he is 100 percent healthy.
"At this point, it's day to day," Melvin said. "We're going to make sure he's not pushing it and going out there a little bit nicked up."
Weeks is in the thick of a second-base competition with Jed Lowrie and Scott Sizemore, who returned from a bruised hand Tuesday.
Weeks was 6-for-11 with five RBIs in four Spring Training games before he sustained the injury.
"Once he's out there, we don't want to put him in a position where he might have to do some things to work around the injury," Melvin said.
