MIAMI -- The rain didn't dampen Andrew Miller's spirits -- or his pitching.
Miller (2-2) was perfect through four innings, retiring the first 12 batters on just 33 pitches. He allowed one earned run and four hits in 5 2/3 innings and won for the first time in four starts.
Most of the game was played in a steady drizzle.
"It felt good to go out there and I cruised for a few innings," Miller said. "The big thing for me was I've been struggled a lot out of the stretch lately. I felt like when I was in the stretch I was making a lot of good pitches. I was able to command everything."
Down 5-2, the Giants loaded the bases in the ninth against closer Matt Lindstrom. Reliever Leo Nunez gave up Aaron Rowand's two-run single before striking out Edgar Renteria to end it and get his second save.
"We had the tying run on third and we were still fighting," Giants manager Bruce Bochy said. "I thought the guys did a good job of battling out there."
The start of the game was delayed 84 minutes because of rain.
"It's hard to pitch in the major leagues when it's perfect conditions," Marlins manager Fredi Gonzalez said. "I commend [Miller] on how well he handled the situation."
"You're going to miss some pitches and they're going to make you pay," said Sanchez, who had a season-high seven strikouts.
Torres bumped into first baseman Cantu while heading for second and second-base umpire Fieldin Culbreth immediately called interference. Torres continued to run but stumbled and fell between second and third and was tagged in a rundown.
Torres was awarded second base because of the interference call, but Miller retired the next two batters to end the inning with the game tied.
"We didn't give up and that's all you can ask for," Molina said.
Rowand singled in the sixth to extend his hitting streak to a career-high 16 games, the longest active hit streak in the majors.
