A's place Rajai (hamstring) on 10-day DL

ANAHEIM -- Wary of his readiness, the A's opted to place Rajai Davis on the disabled list ahead of Tuesday's opener vs. the Angels, affording the outfielder extra time to recover from a left hamstring strain.
The move was one of many made by the A's, who also recalled outfielder Ryan LaMarre and right-hander César Valdez from Triple-A Nashville and designated righty Raúl Alcántara for assignment.
Davis suffered the injury Thursday and has progressively felt better in the days since. He's eligible to return May 2.
"We just felt like the legs are such a big part of his game that we really wanted him to be at 100 percent, or as close to 100 percent as he could," A's manager Bob Melvin said.
Davis, who was prepping to test his legs at Angel Stadium on Tuesday afternoon, said he feels "great, compared to what I felt a couple days ago."
"Obviously this is not what I wanted to do," he said, "but I don't make that decision, and speed being part of my game, we have to be ready with my legs, and if they're not ready, then I can't really help the team."
Davis appeared to be finding his groove at the plate before being sidelined, enjoying consecutive multihit games after batting just .167 over his previous 11 contests. He's hitting .214 overall this season, with seven RBIs and a stolen base.
LaMarre, acquired from the Angels on Sunday, is also equipped with speed, having racked up 160 stolen bases over eight Minor League seasons with Cincinnati, Boston and Los Angeles of Anaheim. He has just 32 plate appearances in the Majors, his last coming June 27, 2016, for the Red Sox.
LaMarre was in Salt Lake City on Sunday when he got word of his trade to the A's, who then sent him to Colorado Springs to join Triple-A Nashville and DH in Monday night's game. On Tuesday morning, he was back on a plane, heading for Anaheim.
"I couldn't believe," LaMarre said. "They said I was heading to Anaheim, and I was like, 'Wait, am I going back to the Angels?'
"It's a whirlwind, but it's definitely worth it, for sure."
The right-handed-hitting outfielder will likely form a platoon with Jaff Decker in center field, though he can assist at all three outfield positions.
Alcantara was a member of the A's Opening Day rotation, but he stumbled in his first start, prompting the A's to move him to the bullpen. He had pitched in just two games in relief -- his Sunday outing being his first appearance in nine days -- and he had a 16.71 ERA. Valdez takes over the long-relief role.
"We still feel like he has a nice future ahead of him," Melvin said of Alcantara. "But once you get a few outings where it's just not going in the right direction for you, couple that with sitting around … it just kind of mounts on you a little bit, and probably precludes him from performing the way we know he can and the way he expects to.
"If he gets picked up by somebody in the big leagues somewhere, that's great for him. If not, hopefully he stays with us and can get back to the big leagues again."
