Carlos Zambrano won his fifth straight decision and Alfonso Soriano homered in a six-run fifth Monday night as the Chicago Cubs won their fourth straight, beating the San Diego Padres 12-3.

Pitching with an extra day's rest after his start Sunday was scratched because of rainy conditions, Zambrano (6-1) allowed six hits and three runs in seven innings and also chipped in with his bat.

He doubled to start the Cubs' six-run outburst against Randy Wolf (2-3) and added a single in the sixth when Chicago tacked on five more runs.
