Padres 8, Rockies 5: Seth Smith slugged a two-run homer and Yonder Alonso recorded two doubles and two RBIs to lead visiting San Diego past Colorado.

The Padres set season highs by drawing nine walks and turning five double plays in winning for the sixth time in eight games. Pinch hitter Carlos Quentin added a two-run blast and starter Robbie Erlin (3-4) went 2-for-3 with an RBI single.

Troy Tulowitzki was 3-for-4 with a solo homer and Carlos Gonzalez knocked in three runs to pace the Rockies, who had 14 hits but just three with runners in scoring position. Jordan Lyles (5-1), who entered 3-0 with a 1.25 ERA at home, was roughed up for six runs on five hits and six walks in 3 1/3 innings.

Alonso had a two-run double in a first inning that saw Lyles walk three batters and hit another. Chris Denorfia doubled and Smith homered in the second to make it 4-1 and Erlin's run-scoring single capped another two-run rally in the third.

Gonzalez's sacrifice fly in the fourth and two-run double in the sixth helped Colorado get within 6-5, but Quentin launched his first home run since July to open up a three-run bulge. Tulowitzki lined out with runners on the corners to end the seventh and Gonzalez was stranded after opening the eighth with a double before Huston Street recorded his 13th save with a perfect ninth.
