He'll also try to help the Giants regain sole possession of the NL West lead while continuing his success at home against the Colorado Rockies on Saturday.
Cain was honored before Friday's series opener with a plaque commemorating his perfect game on June 13, the first in Giants' history. That victory at AT&T Park over Houston was one of eight consecutive winning starts for the right-hander, but he's 1-3 with a 4.30 ERA in his last eight starts.
Cain (10-5, 3.01 ERA) is also 0-2 with a 5.26 ERA since a 3-2 win over the Astros on July 15 and endured one of his worst outings of the season Monday in St. Louis, giving up five runs over 5 2-3 innings of an 8-2 loss.
"I'm going out there to try and do my job. There's times you give up maybe more pitches in different games. I guess it's just make better pitches and get quicker outs," he told the team's website.
Cain is 3-0 with a 1.50 ERA in his last four home games against the Rockies (41-69) and has recorded wins in the past two overall matchups, the most recent coming Sept. 18. The right-hander, though, will need more runs from his teammates than they produced in Friday's series opener if he wants to earn another victory.
After a 5-2 road trip that included a three-game sweep of Colorado, the Giants (61-52) had only three hits in a 3-0 defeat, their eighth in nine home games. That loss, coupled with Los Angeles' 5-2 win in Miami earlier in the evening, dropped San Francisco into a tie for first with the Dodgers.
The Giants have been shut out five times at AT&T Park and six times overall. They're batting .195 and have been outscored 48-19 over their last nine home games."We go into every game with the same amount of confidence and it doesn't matter where we're playing," said shortstop Brandon Crawford , who had two of San Francisco's three hits. "We just haven't seemed to get hits here lately."
The win, meanwhile, helped the Rockies improve to 3-1 on their six-game trip, and Drew Pomeranz (1-6, 4.76) will try to lead his team to another victory by building on one of his better outings of the year.
The left-hander struck out a career-high seven in a 2-0 victory at the Los Angeles Dodgers on Monday but needed 84 pitches to get through four innings. He was 0-3 with a 9.35 ERA over his previous four starts.
"My mechanics weren't the greatest, but I made it work and gave it everything I had," Pomeranz told the team's website. "I wish I had thrown a few less pitches, but it happens."
Pomeranz will face the Giants for the first time this season and is 1-0 with a 3.97 ERA in two career starts against them. He gave up three runs and six hits over 5 2-3 innings during his only game in San Francisco, a 6-3 win Sept. 28.

SAN FRANCISCO (AP) -- Buster Posey and the San Francisco Giants ' offense broke out at home, and Matt Cain settled in and pitched like the ace of the staff.
It all added up to a one-sided win over the Colorado Rockies .
Posey hit a two-run homer, and Cain tossed seven solid innings in the Giants' 9-3 victory against the Rockies on Saturday.
"We know what our offense is capable of doing," Posey said. "We were coming off a good road trip, and it was nice to see us do the same at home."
Cain (11-5) gave up two runs and seven hits in 7 1-3 innings, and added an RBI single to win for the first time since July 15. He walked one and struck out six. Angel Pagan hit a two-run triple, and Marco Scutaro , Hunter Pence and Joaquin Arias also drove in runs for the Giants.
"I felt like I was able to make better quality pitches this start," Cain said. "My direction was better and I was able to pitch to the outer parts of the plate."
D.J. LeMahieu hit his first major league home run for the Rockies, who had won three of four.
"The wind was blowing out a little bit and that kind of helped it," LeMahieu said. "But to hit it off Matt Cain and here in San Francisco, it was pretty special."
Drew Pomeranz (1-7) gave up four runs and five hits over four innings to fall to 0-4 in his past six starts. He struck out three and didn't walk a batter.
"We had to come from too far back against a very good pitching staff," Rockies manager Jim Tracy said. "You can't beat this team that way. You simply can't do it."
Posey's 19th home run of the season, a two-run shot in the third that landed in the first row of the left field bleachers, gave the Giants a 4-0 lead. It was Posey's ninth homer since the All-Star Break, tying him with San Diego's Chase Headley for the second most in the National League.
"I'm comfortable hitting here and see the ball well," Posey said. "The park is big but all the gaps are big, too."
Cain carried a shutout into the sixth inning, when the Rockies loaded the bases with no outs. He pitched his way out of it, allowing one run on Rutledge's infield groundout.
LeMahieu hit Cain's first pitch of the eighth inning, and Eric Young and Rutledge singled one out later to end Cain's day.
Pagan and Arias tripled, giving the Giants 38 on the season, two shy of the Rockies' major league leading total. There have been 27 triples hit in AT&T Park.
