In desperate need of a fifth starter, the San Francisco Giants have signed pitcher Brad Penny to a minor league contract. Penny will be officially added to the roster when rosters expand Tuesday.

The Giants, who swept the Colorado Rockies over the weekend to capture a tie for first place in the NL Wild Card standings, get a pitcher in Penny who is familiar with the NL West after spending four and a half years in the Los Angeles Dodgers organization. He’ll immediately take the place of Joe Martinez (who was optioned to the minor leagues over the weekend) in the Giants’ rotation.

Penny was 7-8 with a 5.61 ERA and 1.53 WHIP in 24 starts with the Red Sox this season. He was victimized often by the long ball, but should fare much better in the spacious AT&T Park.

San Francisco begins a three-game series in Philadelphia starting on Tuesday and Penny could make his Giants debut as early as Wednesday. He joins one of the best starting rotations in baseball, which also features Tim Lincecum, Matt Cain, Barry Zito and Jonathan Sanchez.

With the Giants set to play their first meaningful September since 2004, oddsmakers from online sports book SBGGLOBAL currently list San Fran’s odds to win the 2009 World Series at 30/1. The Giants’ NL Pennant odds are currently 15/1.
