Starting pitching has become a concern for the San Francisco Giants over the past couple weeks, and Madison Bumgarner is one reason why.
He'll look to end his winless drought as the NL West leaders begin a 10-game homestand against the Colorado Rockies on Monday night.
After Ryan Vogelsong allowed seven runs in 3 1-3 innings of Sunday's 10-2 loss to Arizona that ended a four-game winning streak, San Francisco starting pitchers have a 5.53 ERA since Sept. 2.
The Giants (83-63), who lead the Los Angeles Dodgers by 7 1/2 games, still finished 4-2 on their six-game road trip, taking two of three in Colorado from Monday through Wednesday.
''It was a good road trip,'' said Buster Posey, who is hitting .469 with three homers over his last eight. ''We have to come away happy taking four of six on the road and now we get to go home for 10 games.''
The Giants, though, have gone only 9-15 at home since July 25, and Bumgarner (14-10, 3.32 ERA) is 0-3 with a 7.29 ERA over his last four starts.
The left-hander gave up five runs and 11 hits in 4 1-3 innings against Colorado on Tuesday, but the Giants rallied for a 9-8 victory.
"The ball was up a lot. That didn't work out too good," Bumgarner told the team's official website. "I didn't have very good command of really any pitch away. I pitch in a lot, but you got to be able to throw away, too, and I wasn't able to do that."
He will look to recapture the form that helped him win his previous four starts with a 0.66 ERA against Rockies.
Colorado (58-87) has lost nine of 11 after dropping a 12-11 decision to San Diego on Sunday. It trailed 11-5 heading into the eighth inning before scoring six runs, including a tying grand slam by rookie Josh Rutledge.
The Padres scored in the bottom of the ninth to spoil the comeback bid.
''We just kept battling, every guy,'' said Rutledge, who had gone 0 for 18 in his previous four games. ''Every guy who went to the plate had good at-bats, and we were just trying to string some runs together.''
Colorado has dropped 10 of 14 meetings with the Giants this season, and it will look to bounce back behind Jhoulys Chacin.
Chacin (2-5, 4.86) gave up four runs and six hits in four innings against the Giants last week, allowing a three-run homer to Bumgarner in the fourth inning.
"I was trying to throw a fastball down and away, and that ball just ran back to the middle," Chacin said. "I know he's a good hitter. In the big leagues, whoever is hitting, if you miss your spot, you make your mistake, they'll take advantage of that. It was a really bad pitch to him."
The right-hander hasn't been very good versus the Giants recently, going 0-3 with a 6.10 ERA in his last four starts against them.
Pablo Sandoval is 7 for 16 (.438) with two homers lifetime off Chacin, but he's hitting .174 in five games versus the Rockies this season.
Colorado also has lost nine of 11 on the road.
