Colvin in stable condition, done for season

Cubs rookie remains in hospital after being hit by bat Sunday

CHICAGO -- Cubs outfielder Tyler Colvin, who was impaled by a broken bat in his chest on Sunday, was in stable condition at Jackson Memorial Hospital in Miami on Monday and was expected to stay there a few more days for observation.

"I want to thank Cubs fans for their support all season, especially right now, and let everyone know that I'm doing OK," Colvin said in a statement released by the Cubs on Monday.

"I also want to thank everyone who has helped take care of me here in Miami -- the Cubs and Marlins training and medical staffs, the EMTs at the ballpark and everyone here at the hospital," he said.

Colvin is done for the season after the freak accident. He was on third when Cubs catcher Welington Castillo hit a broken-bat double to left. Colvin was watching the ball, and then turned to head for home. The sharp end of Castillo's busted bat hit Colvin under the collarbone. He was hospitalized for pneumothorax, which occurs when a person has air trapped in the space between the outside of the lung and inside of the chest wall. The air enters the space when there is a hole in the surface of the lung, which allows air to leak from the lung and into the space.

Colvin finished the season with a .254 average, 20 home runs, 18 doubles, five triples, and 56 RBIs in 135 games.

"You never want to have a season end early, and I'm disappointed that I'm not going to be able to make it through the finish line with the rest of my teammates," Colvin said. "That being said, I couldn't be more thankful for the Cubs organization, my teammates and the opportunity to play for Cubs fans my rookie season. Thank you from the bottom of my heart."

Major League Baseball Commissioner Bud Selig, in New York for the unveiling of a monument of former Yankees owner George Steinbrenner, was asked about the shattered maple bat that sent Colvin to the hospital.

"I talked to Tyler Colvin today. We're down over 50 percent in regard to broken bats. We're using Harvard and the University of Wisconsin, and we're analyzing bats. We're way down. It was very sad. I talked to the young man this afternoon. Hopefully, he's going home tomorrow. We've been very vigorous on this subject and will continue to be so."
