The left-hander has pitched well lately, though, and he'll try to help the San Francisco Giants avoid a seventh consecutive loss and their first three-game sweep in Colorado in 11 years.Cuddyer wasted little time adding to his streak Saturday, pushing it to 26 games with an RBI single in the first inning. The Rockies (41-41) didn't score again in the 2-1 victory until Nolan Arenado singled in the ninth to end the game."A lot of positives today," manager Walt Weiss said. "A lot of great things happened today. ... Cuddy extending his streak, lot of good storylines today."Cuddyer is batting .376 during the streak but just 2 for 9 in this series, though he did hit a two-run homer in Friday's 4-1 win.Given Bumgarner's recent problems against him and in Colorado, it would appear Cuddyer has a prime chance to top the longest streak in the majors from 2012 -- Jose Reyes' 26-gamer for Miami. A 27-game streak would be MLB's longest since Dan Uggla's run of 33 straight for Atlanta from July 5-Aug. 13, 2011.Bumgarner (7-5, 3.20 ERA) is 0-1 with a 12.00 ERA in his last two starts at Coors Field and was tagged for a career-high nine runs over 4 2/3 innings in a 10-9 loss there May 17.Cuddyer was on the disabled list that day but went 2 for 2 on April 8 in his only matchup this season with Bumgarner, who would allow only three other hits in 5 2/3 innings and beat the Rockies in a 4-2 win at San Francisco (38-42). Cuddyer is 3 for 6 with a double and a walk lifetime against him.Bumgarner, though, has completed seven innings in three straight outings, allowing a combined four earned runs and 10 hits while striking out 23. He did have a three-game win streak snapped Monday with a 3-1 loss to the Los Angeles Dodgers.Before his miserable outing in Colorado last month, Bumgarner was 6-1 with a 1.88 ERA in a 10-start stretch against the Rockies. His only poor performance in that span came at Coors on Sept. 11, when yielded five runs and 11 hits over 4 1/3 innings in a 9-8 win.The Giants haven't been nearly as helpful on offense of late, batting .209 and scoring 12 runs during their longest losing streak since a seven-game skid June 26-July 2, 2010. They're also on the verge of their first eight-game road losing streak since May 12-20, 2000, and their first three-game sweep in Denver since May 24-26, 2002."It's not a good stretch," manager Bruce Bochy said. "I'll leave it at that."San Francisco, however, will face a pitcher who is making his season debut for the Rockies. Drew Pomeranz is being called up after going 8-1 with a 4.20 in 15 starts for Triple-A Colorado Springs this year.Pomeranz is 4-10 with a 5.01 ERA in 26 career starts for the Rockies, including 22 last season. He's 1-1 with a 5.28 ERA in three against the Giants.The Rockies are seeking their first three-game win streak since May 21-24, which was capped by a 5-0 victory in San Francisco. Colorado has won five straight home games against its NL West rival and six of eight overall meetings.
