CHICAGO -- Indians center fielder Grady Sizemore will be out for the rest of the 2010 season, after having microfracture surgery on his left knee in Vail, Colo., on Friday.

Dr. Richard Steadman planned to go in and evaluate the strength of the joint. When he was looking, he determined the cartilage in the knee was unstable and went through with microfracture surgery.

"We were hoping that he wouldn't have to have the microfracture surgery, but this is what's going to be best for him," manager Manny Acta said. "This is what's going to give him a chance to play longer, probably for the next 10 years, and be as healthy as he can. What's good for him is good for us. Everybody knows over the last six or seven years what Grady represents to this ballclub."

The surgery generally has a six- to nine-month recovery window, meaning that Sizemore should be back during Spring Training 2011. Sizemore is expected to have a full recovery.

"Grady also said, 'I want to have one knee operation,'" trainer Lonnie Soloff said. "Grady will be back in Cleveland on Thursday."

Kearns moves to third spot in lineup

CHICAGO -- Austin Kearns started in the third spot of the batting order for the Indians during Friday's game against the White Sox, despite his recent struggles.

Kearns entered Friday hitting 4-for-22 on the current road trip, with two RBIs. He singled in his first at-bat against John Danks.

"We're still satisfied with the way he's swinging the bat," manager Manny Acta said. "He's hit some balls hard this road trip, but it hasn't happened for him. We're still very grateful to have him over here, because without him, I don't know where we would be.

"He's really picked up a lot of RBIs that we weren't anticipating him to have. We were anticipating him to be our fourth guy here. He comes in cycles. He continues to have good at-bats, and hopefully balls start falling for him again."

Crowe receives off-day against White Sox

CHICAGO -- On a day when the Indians' star center fielder, Grady Sizemore, learned he would be out for the remainder of the season, manager Manny Acta chose to give the replacement center fielder, Trevor Crowe, the day off on Friday against the White Sox.

Furthermore, shortstop Jason Donald led off on Friday for the first time this season, and Austin Kearns shifted to center field, his second start there in 2010.

Acta said that anyone who disparages Crowe's defensive prowess in center field is unfairly comparing him to Sizemore.

"He's been OK back there," Acta said. "It's really tough to play center field. Anybody who comes after Grady, it's not fair. [Crowe has] done a decent job out there for us. We're giving him an opportunity to find more consistency, at the plate, a higher on base percentage, and help us create some stuff on the basepaths."

Herrmann's family hopes to see his debut

CHICAGO -- It takes a village to raise a professional ballplayer, and for newly minted Indians pitcher Frank Herrmann, it seems that entire village is coming to see his debut.

Herrmann, a reliever who posted a 0.31 ERA this season for the Triple-A Columbus Clippers, had eight people traveling from Boston and New Jersey with hopes of seeing him in his Major League debut.

"It's very exciting," Herrmann said. "It's funny because everyone always says, 'If you get called up, I don't care where it is, I'm coming.' And to actually do it is a really cool experience."

His parents and younger brother, Max, are driving from New Jersey for the sole purpose of seeing him pitch in the Majors -- but the family is going back after Saturday's game because of Max's finals in high school.

Herrmann's fiancé, who has been dating him since he was a pitcher at Harvard University, flew in to be on hand for his MLB debut.

"She got in at, like, 1:43 in the hotel room, and I had to be on the bus at 1:45, so we were two strangers in the night," Herrmann said. "I just gave her a quick hug. She's been with me all five years while I was in the Minors, so this is just as much a thing for her as for me. And then, I had to get on the bus."

To make space for Herrmann, the Tribe had to designate Jamey Wright for assignment, but it was not due to his performance, according to manager Manny Acta.

"I think, with the way he pitched, I'm pulling for him to get another opportunity," Acta said. "He showed some stuff for us out there, and he has some experience. We just couldn't afford to keep this kid down there any longer with the way he was throwing the ball."

Herrmann left the Indians no choice with his sparkling ERA.

"Even if it is in my backyard pickup game, a 0.30 ERA is pretty good," Acta said. "I'm very happy for him. He worked hard through our farm system, and he earned it. He earned his shot. He wasn't even [on the 40-man roster], but he came to big league camp [in Spring Training] and threw the ball well. Then he went to Triple-A."
