After a six-run, seventh-inning rally helped them stun the Rockies on Tuesday night, the Giants will look to ride that momentum to a series win and a season-series win against last-place Colorado. The clubs have split their first 18 games heading into their last matchup of 2014.
Sitting two games behind the first-place Dodgers, the National League Wild Card-leading Giants will turn to Ryan Vogelsong on Wednesday, hoping he can control a Rockies offense that scored six runs off starter Yusmeiro Petit on Tuesday.
Vogelsong has pitched well lately, but the Giants are only 3-3 in his last six outings, which hasn't necessarily been Vogelsong's fault.
He has given up more than two runs only once since the start of August and went six or more innings in four of them.
In Vogelsong's last start, he pitched seven innings while giving up two runs and striking out seven in the Giants' 13-2 win against the Brewers on Aug. 29.
The veteran Vogelsong will face a much less experienced pitcher -- rookie Christian Bergman.
Bergman, who will be making only his sixth career start, was formidable in his last outing, which came against the D-backs at Chase Field.
Bergman walked five D-backs and didn't get a decision, but he didn't give up a hit until there were two outs in the fifth and he allowed only one run on two hits in 5 1/3 innings.
He will try to deliver Colorado's first season-series win over San Francisco since 2008.
Giants: Morse likely out for road trip
First baseman/outfielder Michael Morse could miss the remainder of the Giant's road trip due to a strained right oblique.
Manager Bruce Bochy said Morse is out Wednesday and "questionable" for the Giants' next series, a three-game set with the Tigers in Detroit. However, Bochy said Morse could return for a six-game homestand on Tuesday.
Morse, who had an MRI exam on Tuesday, has played in 130 games this season, which is 16 shy of the career high he set in 2011.
Morse has a .280/.338/.477 slash line this season and has a 1.1 WAR (wins above replacement), according to Fangraphs.com.
Rockies: Reinforcements coming from Tulsa
The Rockies would have already brought up players to fill their expanded September roster, but Double-A Tulsa has thrown a wrench in their plans -- by doing well.
The Drillers are taking on the Arkansas Travelers, the Angels' Double-A affiliate, in the first round of the Texas League playoffs.
Two possible pitchers who may be in Rockies uniforms when Tulsa's season ends, Eddie Butler and Texas League Pitcher of the Year Tyler Anderson, will likely start the first two games of the best-of-five series.
However, top prospect Jon Gray will almost certainly not be among those called up when Tulsa's season ends. Gray has been shut down for the first round of the playoffs with mild soreness in his right shoulder.
The right-handed Gray, who is the Rockies' No. 1 prospect, finished his season with Tulsa with a 1-5 record and 3.91 ERA.
• With Tuesday's callup of his son, Brett Bochy, Bruce Bochy became the seventh skipper to manage his son in the Major Leagues.
• The Rockies activated reliever Tommy Kahnle from the 15-day disabled list Tuesday. Kahnle had been on the DL with right shoulder inflammation since Aug. 16.
