Ian Kennedy struck out nine in six strong innings and Yonder Alonso hit a two-run homer to lead the San Diego Padres past the Chicago White Sox 4-1 on Friday night.
Cameron Maybin hit his first home run of the season and Alonso finished with three hits as the Padres ended Chicago's three-game winning streak.
Kennedy (4-6) allowed one run and four hits with three walks. The lone run was set up by Maybin's mental lapse in the fourth inning.
Padres closer Huston Street pitched a perfect ninth for his 16th save in 16 opportunities. Nick Vincent and Joaquin Benoit backed up Kennedy with a scoreless inning apiece.
Kennedy has struggled to get help from San Diego's offense. Before the game, he ranked 98th out of 101 qualified pitchers with 2.79 runs of support per nine innings. He struck out the side in the fifth and Conor Gillaspie leading off the sixth.
