SAN FRANCISCO (AP) — Ryan Vogelsong and two relievers combined on a three-hitter and the San Francisco Giants completed their first series sweep of the season with a 3-0 win over the slumping Colorado Rockies on Sunday.

Cody Ross homered and drove in all three runs to help the defending World Series champions beat the Rockies for the third straight day and pull within a game of the NL West leaders.

Vogelsong (2-0) was perfect through five innings and didn’t allow a hit until Chris Iannetta’s leadoff single in the sixth. The 33-year-old right-hander struck out four and walked one in 6 1-3 innings.

Javier Lopez pitched 1 2-3 innings and Brian Wilson worked the ninth for his 11th save in 12 chances.
