An MRI exam Monday on the All-Star center fielder's ailing left elbow revealed much of the inflammation that's hampered him since spring training has subsided. Arthroscopic surgery was an option.
"You hate to put a timetable on anything," Indians manager Eric Wedge said. "That would probably be a best-case scenario.
"There's still something there. But it looks a lot better than the last MRI he took."
Sizemore will test the elbow with more swings and throws Tuesday, and he will be evaluated daily. No more MRI exams have been scheduled.
"There's a chance it could get worse, there's a chance it could stay the same," Sizemore said. "It's not necessarily black and white. It definitely could linger all year. It's just a matter of how much worse it gets. It had started making the muscles and ligaments around the elbow sore. We don't want to go back to that. If it goes back to that, we have to make a decision [on surgery]."
As long as it doesn't get any worse, Sizemore said he could play the rest of the season with the pain he has now. The elbow affects his throwing more than hitting, but he felt good throwing from 60 feet Monday. It was the first time he has thrown a baseball since May 24. He spent the last week before going on the disabled list as the designated hitter.
Sizemore is batting .223 with nine homers and 31 RBIs in 49 games this season.
"The key right now is to see how it feels as we go forward," Sizemore said. "It feels better than when I went on the DL. We'll step it up a little bit tomorrow, take some more swings and see how it feels from there."
In other injury news, the Indians have scratched Jake Westbrook's next rehab start, scheduled for Wednesday night, because of general soreness. Westbrook, recovering from ligament transplant surgery last summer, threw four scoreless innings Friday night for Double-A Akron.
Instead of Wednesday's start, he will throw a bullpen session.
"We expected him to see it [soreness] a lot earlier than this," Wedge said. "It's just a little soreness after his last outing. He hasn't had any setbacks at all. It's really gone very smoothly. We'll see how he is tomorrow and go from there."
