Carlos Zambrano shook off a cramp in his pitching arm, then shut down the Milwaukee Brewers.
Zambrano (1-0) pitched one-hit ball into the eighth and had two singles and an RBI to help the Chicago Cubs deal Milwaukee its first loss of the season, 4-0.
Zambrano gave up only a two-out line single in the second inning to Russell Branyan, and shut down a Brewers lineup that scored 25 runs in the first three games. He struck out six and walked two while outpitching fellow opening-day starter Ben Sheets (1-1).
But after throwing just one pitch to the second hitter of the game, Junior Spivey, Zambrano stepped off the mound, pointed to his pitching arm and signaled for Cubs trainer Mark O'Neal.
Zambrano was allowed three additional warm-up tosses. He then struck out Spivey on the next three pitches and cruised until being relieved by Chad Fox with one out in the eighth.
"It happens to me all the time," Zambrano said, referring to the cramp. "I have to drink more water. It has nothing to do with my elbow or shoulder."
Cubs manager Dusty Baker, whose team snapped a three-game losing streak, said the same thing happened to Zambrano in a game last season.
"I'm just glad it was muscle and nothing else," Baker said. "He was throwing great from the beginning. He hit well, he ran well, he did everything well today.
