The two absences leave an Indians team already struggling to generate runs without its Nos. 1 and 2 hitters.
"It's tough, it's very tough," manager Manny Acta said of losing Cabrera and Sizemore. "I don't think anybody anticipated losing two of our best players here. But everybody has their problems. Nobody said it would be easy."
Shelley Duncan was called up from Triple-A Columbus to take Sizemore's active roster spot. Duncan claimed the 40-man spot of Cabrera, who was officially moved from the 15-day to the 60-day DL.
Duncan, who was batting .301 with six homers and 34 RBIs in 38 games with the Clippers, can fill in as a right-handed power bat against lefties when designated hitter Travis Hafner, right fielder Shin-Soo Choo or first baseman Russell Branyan get a day off.
As far as replacing Cabrera and Sizemore is concerned, Jason Donald was called up Tuesday to take Cabrera's active roster spot and contributed two hits and a walk in his Major League debut. Trevor Crowe, who was 5-for-15 since his promotion from Columbus on Sunday, is currently taking Sizemore's place in center. Left fielder Austin Kearns can also be shifted over to center.
Cabrera and Sizemore suffered their injuries on consecutive days. On Sunday in Baltimore, Sizemore injured his knee when diving back to the bag after a fifth-inning single and had to come out of the game. Cabrera broke his arm on a collision with third baseman Jhonny Peralta in the first inning Monday night at Tampa Bay. The two infielders were on an infield shift toward the right side and were both going after a Hank Blalock grounder up the middle.
This marks Sizemore's third trip to the disabled list in the past year. He had been the Tribe's iron man prior to experiencing elbow and abdominal issues in 2009.
Sizemore was struggling at the plate from the outset of this season, batting just .211 with no homers and 13 RBIs in 33 games. He was in a 1-for-14 funk at the time of the injury.
But Choo said losing Sizemore, regardless of his stats, is a big blow, especially when paired with the Cabrera development.
"It's tough, man," Choo said. "Grady, I know he didn't have the numbers, but when he's not in the lineup, that's a big difference. Cabrera, same thing."
Cabrera's prognosis was not unexpected. Soloff explained that his fracture was displaced, meaning the bone was out of line. Had it been non-displaced, his arm would have healed in a cast. But in this instance, surgery was necessary. Soloff was not yet sure whether screws were needed to mend the fracture.
