"Last year, I had the opportunity to see him play from the other side," Reyes, formerly with the Mets, said of Stanton. "Now we're on the same team. It's unbelievable. I feel like every time he goes to home plate, he's going to hit a home run. That's the way that I feel."
Greg Dobbs added a two-run homer in the ninth inning, giving Miami four shots on the night. Bryan Petersen added a three-run triple in the eighth in a 13-hit attack.
The 13 runs were a season high for Miami. For only the second time this year, the Marlins reached double digits in runs, but this time it resulted in a win. On July 3 at Milwaukee, they lost 13-12 in 10 innings.
"We've waited three months to finally get one of these," manager Ozzie Guillen said. "It was fun. I think lately, we're starting to enjoy this game a little bit. There is more action with our offense."
The team's nine extra-base hits were the most since it had 10 against the White Sox in Chicago on May 23, 2010. The lopsided affair matched the second-largest shutout victory in club history.
"We are all swinging the bat well, and we fed off each other," Stanton said. "That's what made it all work."
The big offensive outburst provided Nathan Eovaldi with plenty of support to collect his second win in three starts since being acquired from the Dodgers as part of the Hanley Ramirez trade on July 25.
Eovaldi didn't allow a run while giving up four hits in five-plus innings, but he walked six, a season high. He hadn't walked more than three since issuing four free passes to the Rockies on June 3.
"It's always great to get early run support," Eovaldi said. "I got myself into trouble with a lot of leadoff walks, but I was able to make the pitches when they really mattered."
Stanton missed a month after undergoing surgery on July 8 to remove pieces of loose cartilage. He returned to the lineup on Tuesday and drove in a run on a sacrifice fly in Miami's 4-2 win.
"I don't know why I predicted that," Guillen said. "But yesterday, I saw his swing, and I knew this kid was pretty close to having a monster day. He did today."
In the 25 games the All-Star right fielder was out, the Marlins hit 13 total home runs. They connected on four -- three off New York right-hander Chris Young -- on Wednesday.
Young praised the Marlins slugger after his 4 1/3-inning outing.
"He's a great hitter, he's extremely talented," Young said. "The second home run, he crushed. The first one, he didn't even get and he still hit it out, he's that strong. Hopefully next time I face him, I've got a better idea of what I want to do, but it wasn't well-executed tonight."
Stanton said he was able to keep his timing through his DL stint by working off a pitching machine.
"I just turned it up faster than any pitcher can throw it," Stanton said. "That's how I got through."
The Marlins have won two straight for the first time since beating the Padres on July 28-29.
A sore right hand has bothered Reyes since he jammed it during an at-bat against Washington's Gio Gonzalez last Friday. Guillen considered resting Reyes on Wednesday, but the four-time All-Star shortstop insisted on playing.
If the hand was bothering him, Reyes didn't show it when he crushed a home run that landed in the second deck in right field in the first inning. It was his eighth homer of the season, and the blast prolonged his streak.
"I'll take it. A hit's a hit," Reyes said. "I don't hit too many home runs, but when I hit one, I'm going to enjoy the ones that I can."
Miami wasn't through in the first inning, as Stanton uncorked a two-run homer -- a towering drive to left that barely cleared the wall. It was Stanton's 20th shot of the season, and first since July 1 against the Phillies.
The Marlins broke the game open with four runs in the fifth, an inning where they relied on their speed and power.
Justin Ruggiano got it going with a one-out, ground-rule double. Reyes walked, and both runners moved up on a double-steal. The Mets played their infield in, and Carlos Lee floated a soft fly ball that fell for a two-run single. Had the infield been deep, the ball likely would have been caught.
Lee is quietly riding a 13-game hitting streak.
Stanton punctuated the inning with a laser shot to left, his second two-run blast of the game. Young was promptly lifted after allowing seven earned runs.
"It's good to get into a little groove there, and hit the ball hard in back-to-back at-bats," Stanton said. "I didn't feel too off last night."
