"He's real capable of being an All-Star, he should be," Marlins closer Heath Bell said. "He's one of those guys that should be starting in a couple years. Maybe next year people start really seeing who he is and start voting him in."
Stanton's estimated 424-foot shot in the first off Cole Hamels (10-4), his 18th homer, gave the Marlins a 1-0 lead.
"Wait a couple more years, this kid is going to be very dangerous," Marlins manager Ozzie Guillen said.
Miami took a 2-1 lead on Stanton's RBI single in the third after Shane Victorino's sacrifice fly tied it in the second.
"You don't always need to hit it 400 feet to get an RBI," Stanton said.
Rosters for the All-Star Game in Kansas City on July 10 will be announced Sunday.
Marlins starter Mark Buehrle (7-8) pitched seven strong innings as he allowed two runs and seven hits. He struck out seven and walked one.
"[The Phillies] are a good team, they are getting guys back, which makes it scary," Buehrle said.
Jose Reyes had two hits, stole two bases and scored twice for Miami.
"Every time Jose is on fire, he makes things happen," Guillen said. "This kid is our igniter."
The Marlins' winning streak is their longest since sweeping a three-game series from Washington on May 28-30. They finished 8-18 in June after posting a 21-8 record in May.
"We need to put this month in the past and take July on," Stanton said.
Hunter Pence homered and had three hits for the Phillies, who have lost four straight.
"I think we can turn things around, but at the same time we've got to play a hell of a lot better," Phillies manager Charlie Manuel said. "We have to play over .600 baseball the rest of the way. I've seen us hit some big streaks, so it's possible, but I think everybody has to get to get it going right now."
Pence's solo home run in the seventh off Buehrle cut the deficit to 3-2, but Buehrle was able to finish the inning.
"Not too many people appreciate the way [Pence] plays," Guillen said. "He's a bad man against the Marlins. He can do everything."
Mike Dunn pitched a perfect eighth before Heath Bell came in to pitch the ninth. Bell allowed a one-out double to Carlos Ruiz before striking out Pence and getting Shane Victorino to ground out for his 16th save in 20 chances.
Cole Hamels (10-4) fell to 0-3 against the Marlins this season. He gave up three runs and seven hits in seven innings while striking out five.
"They've been a tough team to pitch against," Hamels said. "There's times I'm really able to control the pitch sequence and get them out, but when it gets into crunch time it's been tough to get the strikeouts or the double plays."
The Marlins Park crowd of 31,311 saw the fastest home game of the season at 2 hours, 20 minutes.
Reyes was the catalyst for the Marlins' third run as he led off the fifth with a single, then stole second and third base. Justin Ruggiano hit a sacrifice fly to deep center to score Reyes.
