The NL West rivals continue their three-game series Tuesday night as the Rockies try to win for the ninth time in 11 games.
Colorado (62-71) ended San Francisco’s season-high five-game winning streak with a 4-2 victory on Monday. The Rockies, who have struggled away from Coors Field for most of the season, have won 12 of their last 17 road games.
“It all comes down to execution,” Rockies manager Clint Hurdle said. “We just did not execute well at home early and we didn’t execute well on the road early. We’ve been on a nice little roll now.”
San Francisco (58-73) had a chance to move ahead of Colorado for third place in the division with a sweep in this series. The Giants, instead, remained 10 games behind first-place Arizona in the NL West while the Rockies pulled within seven games of the Diamondbacks.
Still, San Francisco has won eight of its last 11 games while the defending NL champions have won eight of their last 10.
The division rivals have now split 10 meetings this year after Yorvit Torrealba homered and Ian Stewart scored twice in Monday’s win for Colorado. Troy Tulowitzki tripled in the go-ahead run in the fifth inning and Manny Corpas and Brian Fuentes each worked a scoreless inning to preserve the win for Jeff Francis.
The Rockies’ bullpen has been solid against the Giants all season, posting a 2.83 ERA and allowing one run in 10 1-3 innings in four games at San Francisco.
Rookie Matt Palmer (0-1, 8.64) will make his third career start for the Giants. His major league debut was a tough one as he was tagged for six runs over 2 1-3 innings in an 11-5 loss at Atlanta on Aug. 15.
The 29-year-old right-hander was much better in his next outing, yielding two runs in six innings against Florida on Thursday. He left with a 3-2 lead that the bullpen failed to hold in the Giants’ 4-3 victory.
Jorge De La Rosa (6-7, 5.86) will start at AT&T Park for the first time in his career. His lone career start against the Giants came on May 19 when he yielded three runs in 5 1-3 innings and did not get a decision in a 4-3 victory.
The left-hander has been sharp in his last two starts, going 1-1 with a 3.00 ERA. He allowed two runs over six innings to lose 3-1 to the Los Angeles Dodgers on Thursday.
