PHILADELPHIA -- Henderson Alvarez has found success by simply throwing low strikes.
Alvarez (5-3) allowed two runs -- one earned -- and seven hits. He is 3-0 with a 0.78 ERA in his last seven starts.
"I've been working hard to keep my pitches down in the zone," Alvarez said through an interpreter. "All my pitches, curveball, fastball and change."
The Marlins have won two of the first three in the four-game set. They had lost eight of their previous nine games in Philadelphia before this series.
Steve Cishek struck out the side in the ninth for his 18th save in 19 tries.
The Phillies are 1-4 since a season-high five-game winning streak that included a three-game sweep at Atlanta and two wins in St. Louis. They are just 17-23 at home.
Miami improved to .500 at 39-39 and trails NL East-leading Washington by only 2 1/2 games.
The Marlins had runners on first and second with two outs in the fourth when Marcell Ozuna hit a liner to left that should have ended the inning. But Brown froze on the ball instead of taking a step back and it sailed over his head for an RBI double.
"That play has to be made," Brown said. "I told A.J. I was sorry about it. It was a hard-hit line drive. I made a break on it in and that definitely was a big mistake. I'm definitely upset at myself."
Saltalamacchia followed with a two-run double to left-center to make it 3-0. He was 1 for 15 with nine strikeouts off Burnett before the hit.
"Salty put a great at-bat together and drove in a couple runs. He did a great job behind the plate, too," Marlins manager Mike Redmond said.
Brown, an All-Star last year when he led the Phillies with 27 homers, has played shaky defense. He is hitting just .217 with five homers.
Brown's RBI single in the sixth got them within 3-2. Marlon Byrd started the inning with his third hit and advanced on a groundout before scoring on Brown's liner to right-center.
Burnett began his career with the Marlins, going 49-50 in seven seasons. He is 2-2 with a 2.59 ERA in his last four starts after going 1-4 with a 7.25 ERA in his previous six.
Alvarez has allowed just four earned runs in his last seven starts. He started his turnaround against the Phillies on May 22 when he tossed four-hit ball over seven innings.
"He's pitching with confidence and he's starting to understand what he can do and how good he can be," Redmond said.
Alvarez pitched out of a jam in the second. He struck out Brown with one out and runners on first and third. He then retired Burnett on a bouncer to third to leave the bases loaded.
"Alvarez had real good secondary stuff and moved the ball around," Saltalamacchia said.
