LAS VEGAS -- Jeff Baker's time in the Pacific Coast League gave him a good look at the ballpark in Las Vegas.
The experience helped Sunday.
Baker, who went 3 for 3, drove in Steve Clevenger from third base for the winning run.
"I was just looking for something outside over the plate, and I was able to get a good swing on it," Baker said. "I played for [Triple-A] Colorado Springs. Familiarity with the park got me going up there. I kind of knew what to expect, what was going on."
Baker, who now has a .393 batting average, also tried to start a go-ahead rally in the ninth, when he led off with a double to left-center field. But the Cubs were unable to advance him any further.
"[I] play every game to win and want to have good at-bats," Baker said. "Everyone just wants to progress for the season."
Hector Giminez opened the eighth for the Dodgers with a solo homer that tied it at 3.
Although Zambrano batted in the fifth, he did not return to the mound for the sixth. Zambrano finished with three strikeouts and one walk while allowing six hits and one run.
