Chicago ? Mike Piazza had his first four-hit game of the season Friday, and the San Diego Padres won for the 12th time in 13 games, beating the slumping Chicago Cubs, 10-5.

Piazza doubled in the go-ahead run in the fourth. And the Padres broke open the game with five runs in the fifth, thanks to three errors by the Cubs, who have lost 12 of 14 games.

San Diego’s Dave Roberts extended his hitting streak to 10 games, going 3-for-4 and scoring three runs. And Brian Sweeney (2-0) allowed one run in three innings of relief, after starter Woody Williams strained his left calf running the bases in the second.

Chicago’s Glendon Rusch (1-5) allowed six runs (five earned) in 12â3 innings of relief.

Piazza, batting .220 entering the game, drove in Roberts with a double to left with two out in the fourth to give the Padres a 3-2 lead. Piazza’s last four-hit game was last season with the Mets on May 18 against Cincinnati.
