Patrick Corbin worked six innings without his best stuff to become the first Arizona left-hander to start with eight straight wins, Martin Prado matched a career high with four hits and the Diamondbacks beat the San Diego Padres 6-5 on Sunday.
Corbin allowed more than two runs for the first time this season, but helped himself with a run-scoring single in the fifth inning off Tommy Layne (0-1) to become the third Arizona pitcher to start a season 8-0.
Eric Chavez homered for the second straight game, Prado drove in a run in the seventh inning after getting three hits the night before and Heath Bell worked a perfect ninth for his eighth save.
Carlos Quentin hit a two-run homer and Kyle Blanks also had two RBIs for the Padres, who have lost four of five.
