SAN DIEGO (AP) — Tyler Chatwood took a shutout into the seventh inning and the Colorado Rockies beat skidding San Diego 4-2 on Monday night, handing the Padres their 10th consecutive defeat.

Wilin Rosario hit a two-run double and Jonathan Herrera drove in a run with a bunt to help the Rockies end a three-game slide with their second victory in eight games. They have won nine of 11 against San Diego this season.

Chatwood (5-2) allowed two runs and five hits in a season-high 6 2-3 innings. He walked four and struck out three. The right-hander is 3-1 in five road starts this season with a 1.35 ERA.

Matt Belisle pitched a hitless eighth and Rafael Betancourt worked the ninth for his 12th save in 13 opportunities.
