Indians manager Manny Acta insists that Sizemore is healthy.
"Right now, health is not an issue," Acta said. "We haven't had any type of setbacks with his health. We're still going to have to manage his playing time, but none of that has been attributed to the health, not by him and not by our medical staff."
Sizemore started the season on the disabled list, but rejoined the Indians in mid-April after a 10-month recovery from microfracture surgery on his left knee. In May, the center fielder missed two weeks due to a right knee injury. Sizemore entered Sunday's finale against the Giants hitting just .177 since coming back from the 15-day DL on May 27.
The slump extends beyond that, though.
Entering Sunday's game, Sizemore had hit .183 (26-for-142) with a .612 OPS over 36 games, dating back to April 27. He was also hitting at a .145 (9-for-62) clip with a .508 OPS over his past 17 games.
Acta recently noted that Sizemore was stepping too far toward the plate during his stride, making inside pitches harder to handle. On Sunday, the manager added that Sizemore has been "swinging around the ball" and has been chasing pitches outside the strike zone.
"Guys just go through some struggles," Acta said. "This question wasn't brought up when he was doing really good when he came off the DL [in April]. He's just going through some struggles right now and he's going to have to work through it. He's gone through it before."
