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. 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 NL Manager of the Year that season after guiding Colorado into the playoffs.

The Rockies went 294-308 under Tracy.

“I was surprised,” Bill Geivett, the team’s director of major league operations, told The Associated Press. “I wanted Jim to come back. That’s how we began our conversation on Friday, that he was the manager. But he called and informed me today he was resigning.”

ORIOLES: Baltimore kept infielder/outfielder Ryan Flaherty of Portland and 12 pitchers on its roster for the AL division series against the New York Yankees.

Flaherty, a left-handed hitting rookie, has been platooning at second base recently with Robert Andino and wasn’t in the Game 1 lineup against Yankees left-hander CC Sabathia.

Utility players Steve Tolleson and Xavier Avery were omitted in favor of veteran outfielders Lew Ford and Endy Chavez.

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 getting hurt Sept. 19 against the Tigers.

Anderson missed the last couple weeks of the regular season because of a strained right oblique, but the A’s put him on their postseason roster. He was 4-2 with a 2.57 ERA in a season limited to six starts by elbow surgery and the side strain.

Manager Bob Melvin said Anderson feels good, but he wants to wait until Monday to announce whether Anderson will start.

The Tigers, looking to complete a series sweep, will send right-hander Anibal Sanchez to the mound. Sanchez, a former Portland Sea Dog, has been largely lackluster since the Tigers acquired him from Miami in July.
