Mortensen, relievers lead Rockies over Padres

Clayton Mortensen and five relievers combined to help the Colorado Rockies beat the San Diego Padres 3-0 on Monday night.

Mortensen (2-3) and the Rockies relievers shut down San Diego for its 10th shutout of the season, tops in the majors.

The Rockies won for just the fifth time in 17 games, but continued their success at Petco Park where they have won eight of the last 10.

Mortensen allowed five hits in six innings. He struck out three and walked two before he gave way to the relief corp. Huston Street pitched a pefect ninth for his 16th save in 18 chances.

Matt Reynolds, the fourth Colorado reliever, escaped a bases-loaded jam in the eighth inning. Rafael Betancourt started the inning and gave up a single and walk with one out. After he struck out Jorge Cantu for the second out, Reynolds came in and walked pinch hitter Eric Patterson before he struck out Alberto Gonzalez.

San Diego stranded 11 base runners.

Troy Tulowitzki drove in the first run in the first inning and Seth Smith had an RBI triple. Chris Iannetta added a run-scoring single off Ernesto Frieri in the ninth.

Colorado raised its June road record to 3-2, one road win more than it had in May (2-11).

Clayton Richard (2-7) took the loss despite one of his better starts this season. The left-hander gave up one run on five hits over seven innings and struck out a season-high eight with three walks.

The Rockies reached Richard for a run in the first inning after Chris Nelson's one-out triple and Tulowitzki's ground ball that caromed off Richard's foot for an infield single.

San Diego had runners on second and third with one out in the first, but Mortensen struck out Ryan Ludwick and Brad Hawpe to end the inning.

Chase Headley extended his career-high hitting streak to 16 games with a first-inning single.

NOTES: The Rockies have scored three runs or less in 12 of the last 13 games. ... Colorado reliever Rex Brothers made his major-league debut in the seventh inning. ... Colorado CF Dexter Fowler (abdomen discomfort) sat out his second straight game after playing in the first 57. ... Rockies manager Jim Tracy moved slumping OF Carlos Gonzalez into the leadoff slot from the No. 3 hole in the batting order. Tracy said the move was to jump start the struggling Gonzalez, who struck out four times in Sunday's loss at San Francisco. For the three-game series, Gonzalez was 2 for 11 with seven strikeouts. ... Padres 1B Brad Hawpe played RF for the first time this season. Hawpe, who played right field almost exclusively for seven seasons with Colorado and Tampa Bay, had played just nine games at 1B before this season.
