Joba Chamberlain returned to Yankee Stadium Friday night for the first time since dislocating his right ankle in March and said he still intends to be back on the mound in The Bronx by the end of season. "It's going to take a lot of things to stop me," Chamberlain said before the Yankees beat the Tigers, 7-6. Manager Joe Girardi was a bit more cautious in his expectations for Chamberlain, who has been in a walking boot for a week and hopes to be out of that in another week. "I'm not putting a date on him," Girardi said. "If we get him back this year, it's a plus, it's a bonus." Chamberlain suffered the injury while jumping on a trampoline playing with his son in Florida during spring training while he was rehabbing from last year's Tommy John surgery. He saw a doctor Thursday. "It's the first time I got good news from him, I guess," Chamberlain said. "Everything fell back into place."
