Mike Trout (back) will undergo some tests Wednesday. Angels manager Mike Scioscia wouldn't reveal what those tests will be exactly, but the club is trying to get a handle on a back injury that's bother Trout for several days. "Were going to take half a step back," Scioscia said. More will obviously be known about how long Trout might be sidelined after the tests are performed. Fantasy owners are holding their breath.
