SURGERY FOR PEREZ: New York Yankees pitcher Pascual Perez needs arthroscopic surgery on his right shoulder and likely will miss the rest of the season, according to the team's physician.

"I feel bad about it because I will miss the season," said Perez, who signed a $5.7 million contract with the Yankees last winter. "I wanted to pitch better than anybody."

WILD THING: Chicago Cubs reliever Mitch Williams underwent surgery to repair a torn ligament in his knee and will be out for six to eight weeks, the team said.

"It's not going to be the rest of the year," he said. "They're going to have to kill me to keep me out the rest of the year."
