"Any time you ask Bruce Bochy about the Giants' odd, record-breaking streak of solo home runs, the manager lets out one of his basso profundo groans.

"I really know what Earl Weaver meant when he said he liked the three-run home run," Bochy said. "We all do."

Weaver also had pitchers such as Jim Palmer, Mike Cuellar and Dave McNally. The old Baltimore Orioles manager would have enjoyed having Tim Lincecum on his side, too.

Lincecum busted another losing streak while striking out 10 in seven shutout innings, and the Giants got their three runs in three different innings to pull out a 3-0 victory over the Florida Marlins on Saturday at Sun Life Stadium.

A night earlier, Bochy called a clubhouse meeting after the Giants' 11th loss in 14 games, telling his second-place team to straighten up those slumping shoulders and play loose.

That's always a bit easier with Lincecum on the mound.

"Hopefully it'll get us on a win streak and lift morale in here," said Lincecum, who is 4-2 with a 1.11 ERA in six starts since the All-Star break. "Bochy told us we can't hang our heads. This is going to be the toughest part of the schedule going into September. We need to lighten the mood, just go out and have some fun.

"We know where the Diamondbacks are. It's different when you're in the lead. Once they took the lead, it's like we're pressing. We're trying to play catch-up instead of relaxing and playing good ball.

"Nothing comes easy, especially if you're thinking too hard about it. You've just got to go out there with intent and do what's asked of you."

The hitters didn't exactly bust out. Nate Schierholtz scored in the fifth after an error and a wild pitch, and Aubrey Huff's run-scoring double in the sixth was a pop-up down the line that left fielder Logan Morrison dropped.

The Giants' first run, the only one Lincecum would need, came on Jeff Keppinger's first home run as a Giant -- solo, of course. The Giants' 21 consecutive home runs with the bases empty extended a highly undesirable major league record."
