MIAMI — Tim Lincecum received intravenous fluids before his start Sunday night and was under orders to chug a gallon of his favorite electrolyte sports beverage afterward.
He had ice water in his veins, all right.

Dissatisfied with his previous start and disgusted with the pair of 10-hit outings on his record this season, Lincecum showed what happens when he gets ornery on the mound. He took a one-hitter into the eighth inning and trumped another inefficient night from the Giants’ offense, leading the club to a 3-2 victory over the Florida Marlins at LandShark Stadium.
Lincecum (5-1) also doubled and scored a run with an elegant slide across the plate in the fourth inning. The run proved useful in the eighth when Lincecum gave up a two-run home run to Chris Coghlan, the last batter he faced.
New setup man Sergio Romo got the next two hitters, and Brian Wilson allowed two hits before striking out John Baker to end it. It was redemption for Wilson, who blew a save last year when Baker, a Concord De La Salle High alum, hit a tying three-run home run.
Lincecum had no history against the Marlins. It was simply their misfortune to wander down the wrong alley on the wrong night.
The Giants had lost in three of Lincecum’s previous four starts. In the losses, he had opposed the Mets’ Livan Hernandez, the Padres’ Kevin Correia and the Nationals’ Craig Stammen, who was making his third major league start.
Those unexpected defeats had a cumulative effect on Lincecum’s mood.
“Last year, I showed what I think I can do (and) you want to get better,” Lincecum said. “When things don’t go your way, it’s frustrating. You put all this dedication into your sport and it doesn’t pay you back the same way.
“I’ve had games I’ve given up 10 hits. I don’t feel that’s me.”
Lincecum walked the leadoff man in each of his first three innings, but had much better rhythm from the stretch. Ross Gload led off the fourth with a line-drive single, and the Marlins didn’t get another hit until Baker singled to lead off the eighth.
Lincecum’s long locks were pasted to his neck after the first inning, but he wasn’t affected by the humid conditions or the 98-minute rain delay prior to the first pitch — the fifth consecutive night the Giants have been idled.
“All that and he pitches into the eighth inning,” Giants Manager Bruce Bochy said of his 168-pound right-hander. “What a great job. His command was back on target. The last game he wasn’t all that sharp, but tonight he was. He has that look to him. He can’t afford to lose much weight, but I thought he maintained his strength real well.”
Said Lincecum: “It looks like I’m working hard out there, which I am, but yeah, it’d be nice to shut that (talk) down. I’ve had my share of bad games in cold weather, too.”
Minus Lincecum and the bullpen, the Giants played a decisively bad game. They were 2 for 16 with runners in scoring position and ran into three outs on the bases; Bengie Molina and Pablo Sandoval were thrown out at the plate.
“To be honest, sometimes you win a game and you’re not sure if you won it or not,” Bochy said. “We squandered so many opportunities.”
Fred Lewis keyed an important run, though. A day after Bochy essentially declared left field an open competition, Lewis stretched a single into a double, then made an athletic hook slide while scoring on Juan Uribe’s blooper.
The ball beat Lewis to the plate, but he took a wide path and dragged his fingertips across the corner of the plate.
