"Dontrelle is out there yelling at me, `I'm with you, I'm with you. I know it's hot, but I'm with you,'" Burnett said with a smile. "He's sitting in the shade saying all that."
"I've been in a good zone lately," Burnett said. "We're going to go as far as our starting staff takes us."
"We've got a chance to do something great," Burnett said.
The hard-throwing right-hander, who threw a three-hit shutout in his last start to beat Arizona, has an ERA of 1.43 during his winning streak. It began after he became the subject of trade rumors, which ended only when the trade deadline passed July 31.
"Keep the rumors going," manager Jack McKeon joked. "As long as his name was out there being traded, the better he has pitched. So keep trading him."
Burnett, who threw 101 pitches, said he has been more successful since starting to rely more on his sinker. His strikeouts are down -- he had five Sunday -- but so is his pitch count.
He improved to 27-15 in the Marlins' ballpark, breaking the stadium record for victories he shared with Brad Penny.
"It's not really a big record, because nobody sticks around here for too long," said Burnett, a free agent after this season. "Records are like 3000 K's and 300 wins."
Juan Pierre celebrated his 28th birthday with two hits, scored twice and drove in a run. He also made a diving catch of pinch-hitter Randy Winn's fly to short center field with two on to end the game.
Alfonseca got Edgardo Alfonzo to ground into a bases-loaded double play in the eighth, scoring a run, and Pedro Feliz then struck out to end the inning. Jones pitched the ninth for his 25th save in 27 chances.
Brad Hennessey (4-5) allowed four runs and six hits in 4 2/3 innings. He has the worst run support of any Giants starter and left trailing 4-0.
"Sometimes you feel like you have to go out there and be perfect," he said. "You can't let that affect you."
Florida and San Francisco combined for nine runs in the series, with the Marlins winning two of three games.
"We had a shot at winning or losing all three games," San Francisco manager Felipe Alou said. "It was a matter of not being able to deliver a hit here and there."
The Giants fell to 2-4 on their season-high 13-game trip.
Florida scored twice more in the fifth. Pierre singled and took third on a two-out double by Miguel Cabrera, who ended an 0-for-13 skid. Carlos Delgado was intentionally walked, and Alou's strategy backfired when Hennessey hit Juan Encarnacion with a pitch to force in a run, then walked Mike Lowell to score another for a 4-0 Florida lead.
- Giants C Yamid Haad singled in the third for his first major-league hit. He had been 0-for-9. 3B Lowell robbed Haad of another hit in the fifth, making a barehanded grab to throw him out.
- The Marlins won the season series 4-2. Florida is 41-67 against San Francisco.
- Marlins SS Alex Gonzalez went 0-for-4 and stranded seven runners.
