Phillies shortstop Jimmy Rollins has been placed on the 15-day disabled list again after re-injuring his right calf in Friday's 5-1 victory over Boston. Rollins missed 29 games with a strained right calf before rejoining the lineup Monday. He returned to his customary leadoff spot Friday, but left in the sixth inning after feeling a pop while running to first base on a single. An MRI exam Saturday revealed a strain, according to Philadelphia general manager Ruben Amaro. In 12 games, the speedy Rollins is batting .341 with two homers and seven RBIs. He is eligible to come off the disabled list on June 6. http://sports.espn.go.com/mlb/news/story?id=5211189
