Ryan Vogelsong has been a major contributor to San Francisco's success this month.
Looking to continue his stellar May, the right-hander tries to win a third straight road start and help the visiting Giants complete a sweep of the lowly Milwaukee Brewers on Wednesday.
Vogelsong (3-2, 4.60 ERA) went 0-2 with a 9.88 ERA in three April starts but is 3-0 with a 1.05 ERA in four this month. The right-hander allowed two hits over six scoreless innings of an 11-8 victory at Colorado on Friday.
"He just seems to keep guys off balance and makes sure not to let them put the good part of the bat on the ball," teammate Brandon Belt told MLB's official website.
Vogelsong improved to 2-0 and dropped his ERA to 2.70 in five starts at Milwaukee after yielding a solo homer to Carlos Gomez in six innings of a 7-4 victory Aug. 6.
Homers by Belt, Hunter Pence and Matt Duffy helped San Francisco (27-20) improve to 18-7 this month after Tuesday's 6-3 victory at Miller Park. Winners in seven of nine on the road, the Giants last swept a set at Milwaukee from July 5-8, 2010.
Pence is batting .326 with two homers and 10 RBIs in 11 games since making his season debut May 16 following a forearm injury. He's batting .462 with Tuesday's home run and nine RBIs in his last nine against the Brewers (16-31).
Duffy, meanwhile, is hitting .385 with two home runs and 12 RBIs in his last nine road contests.
Among the major league leaders hitting .386 on the road, ex-Brewer Nori Aoki is 7 for 9 in the series.
San Francisco leads the NL with 129 runs and a .298 batting average this month.
Milwaukee is headed in the opposite direction, losing six of seven while totaling 24 runs and hitting .202 during that span.
The Brewers didn't get their first hit Tuesday until Aramis Ramirez homered in the fourth. The veteran third baseman went 2 for 2 with two RBIs after going 0 for 11 in his previous four contests.
Ramirez is batting .333 with two home runs versus Vogelsong.
With Wily Peralta on the disabled list because of a strained left oblique, Milwaukee manager Craig Counsell will start Mike Fiers (1-4, 4.63) on three days' rest. However, the Brewers plan to promote somebody from the minors later this week to take Peralta's spot for the immediate future.
"It gives us some time," Counsell said.
Fiers hasn't received a decision in three straight starts despite allowing two runs in each of those outings. He left after 86 pitches and five innings of a 3-2, 11-inning loss at Atlanta on Saturday.
"I don't think it's a big deal for me," the right-hander said of pitching on short rest. "I didn't really throw as many pitches as I usually do (Saturday). I don't think it's any more stressful than a regular start. I'm fine with it. The team needs me to go and I'll be ready to go."
Fiers gave up three runs, seven hits and struck out nine in seven innings of a 3-1 defeat Aug. 30 in his only start versus San Francisco.
Buster Posey went 0 for 4 versus Fiers in that outing but reached base in a career-high 26th straight game with a walk Tuesday. However, he went 0 for 3 to end his 16-game hitting streak.
