"Center fielder Grady Sizemore left Sunday's game in the first inning with a bruised right knee as the Indians built a 3-1 lead over the Orioles at Camden Yards after three innings.

Following consecutive homers by Travis Hafner and Carlos Santana off rookie right-hander Mitch Atkins, Sizemore blooped a hit into short left field. As he was rounding first, he pulled up not once, but twice before reaching second with a head-first slide for a double.

During his slide, Sizemore was hit by left fielder Matt Angle's throw to second. Sizemore came up limping as manager Manny Acta and trainer Rick Jameyson came out to check on him. After jogging for a bit in center field, Sizemore walked to the dugout and was replaced by pinch-runner Ezequiel Carrera.

Camden Yards has not been kind to Sizemore. Last year he injured his left knee sliding back into first base in May. He needed microfracture surgery in June and missed the rest of the season.

Sizemore has been trying to come back from that surgery, along with an injury to his right knee earlier this season. Sizemore injured his right knee in May sliding into second base against Tampa Bay. He apparently re-injured the knee when he hit first base in the first inning."
