The Dodgers' Matt Kemp, center, is congratulated by Juan Pierre, left, and Brad Penny after hitting a grand slam against the Rockies in the first inning Saturday.

Penny (4-2), a nine-year veteran right-hander, somehow held his emotions in check despite the circumstances. He allowed three runs and four hits over seven innings, including Garrett Atkins’ two-run homer in the first and Todd Helton’s RBI single in the sixth.

“You’ve still got to go back out there and do your job,” Penny said. “It’s part of the game, and it happens — but it probably shouldn’t. It was just a miscommunication with me and Russ. He thought it was going to be a curveball, and when I put my head down, he thought I was ready to make the next pitch.”

Redman (3-1) needed 45 pitches to get out of the first inning in his Dodger Stadium debut, as Los Angeles sent 13 men to the plate and forced the left-hander to throw 45 pitches to get the first three outs.

Kemp drove in the first run with a sacrifice fly, then Redman walked Andruw Jones with two out and the bases loaded, then gave up a broken-bat, opposite-field single to rookie Blake DeWitt on an 0-2 pitch to bring home two more. Penny lined an RBI single to center, Rafael Furcal doubled and Juan Pierre was hit on the right elbow, setting the stage for Kemp’s homer to center field on Redman’s 43rd pitch of the inning.

“Whether his command wasn’t there or he was just trying to be too fine, he kind of just painted himself in a corner where he had to throw strikes and he got in trouble,” manager Clint Hurdle said. “But the command, with the two walks, it started to slide out from him in the first. They just topped it off with the grand slam.”

Redman was charged with 10 runs, seven hits and five walks in six innings with one strikeout. He allowed only one hit after the first — Penny’s second single of the game.
