CLEVELAND -- Michael Bourn was hopeful that his current stay on the disabled list would last only until he was first eligible to return. On Monday, the Indians announced that the center fielder's left hamstring injury is worse than initially believed.
An MRI exam of Bourn's problematic hamstring, which has been an issue off and on since late last season, confirmed a mild to moderate strain. Cleveland indicated that Bourn will likely miss between three to four weeks with the injury.
"It was a little bit more significant than I think we all hoped," Indians manager Terry Francona said on Monday. "I think it kind of shows he's a pretty tough kid. He came in wanting to try to play this weekend."
The latest setback was a frustrating development for Bourn, who relies so much on his speed.
"It is [frustrating]. I've been dealing with it the whole year, pretty much," Bourn said on Sunday. "I guess you could say it's part of the process. I just have to continue to try to get it strong, get it healthy and just be able to come back when I'm ready."
On Sunday, Cleveland selected the contract of rookie outfielder Tyler Holt from Triple-A Columbus to fill the spot vacated by Bourn, who has logged two DL stints due to his left hamstring woes this season. Bourn underwent surgery on the same hamstring on Oct. 15, after tearing it on a stolen-base attempt in Cleveland's Wild Card-clinching game on Sept. 29.
Prior to Monday's game against the Yankees, the Indians added more insurance for their outfield by acquiring Chris Dickerson from the Pirates in exchange for a player to be named or cash. Dickerson started in left field for Cleveland in his first game with the club, which designated catcher George Kottaras for assignment to clear a spot on the active roster.
Bourn, who opened the season on the DL after straining the hamstring during Spring Training, said the latest setback is unrelated to the area of the leg that was surgically repaired. The center fielder said he felt tightness in the hamstring while running from second base to home in the eighth inning of Saturday's win over Kansas City.
"I don't want to go on the DL, but I know it's the best thing for me," Bourn said. "It's sore. I can't say that it's not sore. I know it's sore, so I just have to try to be precautionary with it and try to, when I come back, be OK to play. I don't want to be hesitant."
Through 66 games this season, the 31-year-old Bourn has hit .267 with three home runs, nine doubles, seven triples, seven stolen bases, 21 RBIs and 37 runs scored. With Bourn sidelined, Michael Brantley will shift from left field to center and second baseman Jason Kipnis will move into the lineup's leadoff spot.
Holt, who made his Major League debut as a defensive replacement in right field in the ninth inning on Sunday, posted a .300/.425/.380 slash line through 76 games between Double-A Akron and Triple-A Columbus this season. Overall, Holt piled up two homers, 16 extra-base hits, 21 stolen bases, 26 RBIs and 51 runs scored. He hit .302 (.843 OPS) in 37 games after being promoted to Triple-A.
