Glen Perkins pitched a perfect ninth to collect his 14th save in 16 chances.

The Padres have been shut out eight times, tops in the majors.
Ross struck out eight for the third consecutive start, which is one off his season-high.
Mauer walked with one out in the sixth and stole second off Rene Rivera, who threw out three runners attempting to steal in his last start Sunday in Denver. Plouffe then hit a slow chopper to third and beat Chase Headley's throw, with Mauer moving to third.
Ross breezed through the first five innings, allowing two singles and a walk while striking out six.
Kubel was the only Twin getting into scoring position, advancing to second after walking and stealing second in the second. Kubel was stranded when Danny Santana struck out and Aaron Hicks grounded out.
The Padres, who had hits in each of the first four innings, threatened in the third with two outs when Seth Smith and Headley had consecutive singles. But Alonso, who was elevated to fourth in the order, flied to center.
Another Padres baserunner reached with two outs when Maybin collected his second hit in the fourth, but Rivera struck out to end the inning.
Smith had three of the Padres' eight hits.
