Carlos Zambrano matched his career-high with seven walks in his first start since a June 25 dugout blowup and ensuing banishment, and his short-handed Chicago Cubs lost to the San Francisco Giants 4-3 in 11 innings Monday night long after he left the game.
Edgar Renteria led off the 11th with a single and Aubrey Huff's single moved him to third. Mateo then intentionally walked standout rookie Buster Posey to bring up Burrell.
Chris Ray (5-0) recorded the final out of the 11th for the win.
Burrell had his first game-ending RBI of the season and the 10th of his career. It was his first ever via sacrifice fly.
San Francisco's Travis Ishikawa was thrown out at the plate in the 10th trying to score from first on Andres Torres' double to the deep corner in right.
The Cubs lost their fourth straight and season-high sixth in a row on the road. They last dropped six straight away from Wrigley Field from June 10-25, 2009.
Zambrano returned to the rotation for the first time in six weeks since exploding in the dugout and getting into it with teammate Derrek Lee. Zambrano made three relief appearances since coming off the restricted list late last month after undergoing anger management therapy during his month away.
Alfonso Soriano hit a first-inning RBI double and Marlon Byrd singled in a run that inning as the Cubs gave Zambrano an early boost.
Posey hit an RBI double in the fifth for the Giants, who also pushed across another run on a wild pitch by Zambrano.
Zambrano was in position to win after Tyler Colvin gave the Cubs a 3-2 lead on a sixth-inning single, but the Giants tied it in the bottom half on an RBI single by Torres.
