SAN FRANCISCO -- Some team meetings get better results than others.

After the Giants lost their ninth consecutive home game Monday night at AT&T Park against Seattle, San Francisco manager Bruce Bochy gathered his players in the clubhouse for a meeting before the team's Tuesday afternoon game against the Mariners.

The Giants proceeded to end their home streak in decisive fashion, beating the Mariners 6-2 in the final game of their five-game homestand.

Third baseman Matt Duffy went 3-for-4 with a two-run homer and three RBIs, and right-hander Tim Lincecum held the Mariners to two runs over 5 2/3 innings.

"We had a little discussion about it today," Duffy said of the home struggles. "These fans are too good to for us to be playing the way we have been at home. We've been playing really well on the road, but for some reason or another, it hasn't translated, so we just picked up the focus a little bit. ...

"It's always good to finish a homestand or a road trip on a win and get a happy flight to wherever you're going and carry that momentum to the next series."

The Giants' nine-game skid tied for the second-longest home losing streak in franchise history since 1912, just two shy of an 11-game streak in 1940 at the Polo Grounds in New York.

Lincecum (7-3) allowed five hits and improved to 5-2 overall at AT&T. He struck out three and walked four.

Relievers George Kontos, Javier Lopez, Sergio Romo and Santiago Casilla combined to hold Seattle without a baserunner in the final 3 1/3 innings.

Pinch hitter Casey McGehee hit a two-run double during a three-run eighth inning when the Giants extended their lead to 6-2. Duffy had an RBI single and scored a run in the eighth.

The main message that McGehee took from the team meeting was, "Just kind of let's not freak out here," he said. "We started off the year with a little (losing) streak that was not what we wanted, and we came out of that. The world is not ending around us. Let's keep plugging along.

"Sometimes one big hit like Duff's is really all it takes to let everybody breathe a sigh of relief. Nice to play with a lead."

Mariners left-hander J.A. Happ (3-3) gave up three runs and seven hits in six innings, striking out five and walking two.

Seattle shortstop Brad Miller went 2-for-4 with his sixth homer run of the season, a solo shot. He drove in two runs.

The Mariners went 4-4 on their eight-game road trip, and they open a two-game home series against the Giants on Wednesday.

"It's perception vs. reality," Mariners manager Lloyd McClendon said of his team. "The perception is we're treading water, and the reality is we're not playing as well as we should be playing. Today was a perfect example. We did not get the one hit to get us over the top."

The Giants took a 2-0 lead in the second inning when catcher Buster Posey ripped a leadoff single to left and Duffy launched a two-run shot into the left field seats with one out.

With a 2-2 count, Happ threw a 92 mph fastball, and Duffy hammered it for his sixth home run of the season and third in his past 11 games. Duffy's home run was the first by a Giant during their five-game homestand.

"It's a good feeling," Duffy said. "I think the most important thing was getting on the board first. That's something we haven't been able to do the past week, but whenever you can give pitchers a cushion, they can go out there and attack the zone, and Timmy did a great job of that today once we gave him the lead. He was pretty aggressive in throwing strikes, and he knows he doesn't have to perfect at that point."

Miller cut the Giants' lead in half with a leadoff homer in the fifth. Lincecum threw him a first-pitch curve and Miller lined it over the left-center-field fence for an opposite-field homer. It was his first home run since May 17 against the Boston Red So
