Michael Morse doubled three times and drove in four runs, Madison Bumgarner stayed unbeaten in May and the San Francisco Giants beat the Minnesota Twins 8-1 on Sunday to complete a three-game sweep.

The loss dropped the Twins one game below the .500 mark as they return home to open a series Monday against Texas.

Gregor Blanco had three hits while filling in for leadoff man Angel Pagan and Hunter Pence homered for the Giants, who improved to 6-0 in interleague games this year and improved their majors-leading record to 32-18.

Bumgarner (6-3) earned his fourth straight win while relying mainly on his fastball and slider to baffle the slumping Twins. He struck out 10 with no walks and allowed only two runners past second base.

It was a far different result than Bumgarner got in his only other appearance against Minnesota in 2011 when the left-hander was knocked out of the game after retiring one batter.
