DENVER - Colorado Rockies manager Jim Tracy resigned Sunday, stepping down after the team set a franchise record for losses.

The Rockies said a search for Tracy's replacement would begin immediately but they have no time frame for making a hire. Colorado finished last in the NL West this year while going 64-98.

Tracy was promoted from bench coach to manager in May 2009. He was voted the NL Manager of the Year that season after guiding Colorado into the playoffs.

The Rockies went 294-308 under Tracy.

Energized by a young roster and the challenge of fixing things, Tracy had said he wanted to fulfill the final year on his contract in 2013. But he changed his mind after meeting Friday with Bill Geivett, the team's director of major league operations.

Geivett said he wanted Tracy to return next season.

"I mean, that's how I started our meeting on Friday, that he was the manager of the club," Geivett said. "It was surprising."

Colorado is the fourth to change managers this year. Boston fired Bobby Valentine, Cleveland let go Manny Acta and Houston fired ex-UA Wildcat Brad Mills.

Inside pitch

• Andy Pettitte, set to start Game 2 of the ALDS today, was in his second season with the New York Yankees when they last faced the Baltimore Orioles in the playoffs during the 1996 ALCS. "I remember it was a good series," said Pettitte, who won the clincher and has a 19-10 career postseason record with a 3.83 ERA.

• When the Oakland-Detroit series shifts to the Bay Area for Game 3 on Tuesday night, the A's are hopeful left-hander Brett Anderson will be ready to make his first start since suffering a strained right oblique Sept. 19. Detroit will start righty Anibal Sanchez, who gave up five earned runs to Oakland on Sept. 20 in a loss.

• St. Louis manager Mike Matheny is playing the NL division series with just one left-handed reliever, Marc Rzepczynski.
