CLEVELAND -- Justin Masterson hopes his season isnt over, though the Indians ace realizes the possibility exists. Masterson will miss at least one start because of a strained left oblique, another blow to a team struggling to stay in playoff contention. The right-hander was pulled from Mondays game against Baltimore in the second inning because of soreness in his left side and an MRI on Tuesday revealed the injury. Cleveland manager Terry Francona said Masterson wont resume baseball activities until hes pain-free. An oblique injury takes some players four to six weeks to recover from, which would be too late for Masterson to return. "I dont know," he said when asked if he could be done for the season. "Im sure you get worst-case scenario, whatever it is, that could always be the case. Well take a few days and continue to assess. When its based off how I feel, it makes it a little more difficult to say for sure what its going to be. My hope is to make a few more starts by the time the seasons over and be ready for the playoffs." Francona doesnt know if his No. 1 starter will take the mound again in 2013. "Hell definitely miss a start," Francona said. "After that, you just dont know. Hes going to miss a little time here. The hope would be its not the rest of the season." Mastersons injury is more bad news for the Indians, who have lost six of seven and fallen 3 1/2 games out of the second AL wild-card spot. Reaching the post-season will be even more difficult without their best pitcher. "It could take a short amount of time or it could take little bit," Masterson said. "Were hoping for the shortest bit of time." Masterson, who made his first All-Star team this season, leads the Indians in wins and is tied for first in the AL with three shutouts. The right-hander is 14-10 with a 3.52 ERA in 29 starts. For now, he wont pick up a ball until the pain is gone. "Its not any worse than it was yesterday," he said. "Ive got a touch of soreness over there, maybe a little bit when I cough. Hopefully that will go away in a few days. Im icing and resting and throwing some prayers out there." Despite the fact the Indians are playing poorly in their most crucial stretch of the season, Francona isnt going to rush Masterson back. "Well go on symptoms," Francona said. "We cant let him start doing anything until hes pain-free. Well keep monitoring him and see how hes progressing. Were not going to do something thats not in his best interests." Masterson, listed at 6-foot-6 and 250 pounds, is managing to keep his sense of humour. Asked if doctors found an MRI tube big enough to fit him, he said, "Just barely. We almost went to the zoo." Corey Kluber, who has been on the disabled list since Aug. 6 with a sprained right middle finger, will start Saturday in Mastersons spot against the New York Mets.
