Grady Sizemore had three hits, scored three runs and showed a good glove in the outfield, helping the Boston Red Sox beat the St. Louis Cardinals 10-5 Monday. "I didn't know how the body was going to hold up day to day, if I was going to be able to push it every day," Sizemore said. An AL All-Star in each of his last three full seasons , Sizemore has been hampered by injuries over the last five years and missed the past two seasons following operations on his right knee and back. The solid day boosted his Grapefruit League average all the way to .381 as Sizemore looks to win the starting centerfielder job in Boston away from Jackie Bradley, Jr. Patrick's Day, starter John Lackey gave up five runs, six hits and two walks in five innings with three strikeouts. He was the best center fielder in the game at the time when I played with him, so seeing him back, hopefully he's healthy, and I think he'll be good," said Sabathia.
