"He went out and did some stuff today," manager Terry Francona said Sunday. "In his own words, he says he's 80 percent. That doesn't make much sense for him to play."
Carson, 32, is hitting .292 with four runs, two doubles, a home run, two stolen bases and four RBIs in 15 Cactus League games this spring. He appeared in 20 games for the Tribe last season, going 7-for-11 with a home run and three RBIs.
"I told him, 'We know what you can do.' We also know he's competing," Francona said. "Some of how [the roster is built], when it comes down to the end, are going to be fits. I don't think Matt needs to play today. Saying that, I wouldn't be surprised if he's OK tomorrow."
