Prince Fielder hit a solo home run with one out in the 12th inning and the Brewers, boosted by their fielding gem, beat the San Francisco Giants 2-1 Sunday.

The loss dropped the Giants two games behind Colorado for the NL Wild Card spot.

Fielder hit his 37th home run, connecting against Merkin Valdez (2-1). The slugging first baseman untucked his shirt before reaching second base and jumped on home plate as his teammates fell over backward in unison in a choreographed celebration.

San Francisco led 1-0 when it put Randy Winn on second and Ryan Garko on first in the sixth inning. Aaron Rowand followed with a grounder that third baseman Casey McGehee fielded right on the bag.

McGehee touched third and threw to second baseman Felipe Lopez for the force. Lopez's relay to Fielder beat Rowand by a step and complete a triple play, and pitcher Braden Looper celebrated by pumping his fist.

In the American League, Jon Lester allowed four hits and Boston, boosted by home runs from Mike Lowell and Victor Martinez, beat the Chicago White Sox 6-1 Sunday. Lester fanned eight and became just the 10th different Boston pitcher to reach the 200-strikeout plateau.

After losing Friday and Saturday to the White Sox, Boston increased its AL wild-card lead to three games over Texas, which lost to Baltimore 7-0.
