After he swung on his game-winning hit, Rollins gave the fan a message.
"I politely told him to shut the - up," Rollins said.
Rollins said the fan didn't cross the line by referring to any off-the-field topic.
"It was nothing like that, just a dumb comment," Rollins said.
Rollins hit a 2-2 slider for the game-winner.
"I was trying to drive the ball and was looking for a pitch that I could get, and it didn't matter if it was a curve or a fastball. I told myself, 'When you see it, you will recognize it,' " Rollins said.
The Phillies (5-6) have won the first two of the three-game series against the Marlins. Miami (5-7) has dropped six in a row.
Just as in Friday's 6-3 win, the Phillies jumped to a 2-0 first-inning lead, this time against hard-throwing Marlins righthander Nathan Eovaldi.
The first three batters hit the ball hard. Tony
Gwynn Jr. banged a leadoff double, followed by an RBI single by Rollins, and a run-scoring double by the scorching-hot Chase Utley.
Phillies righthander Jonathan Pettibone, who missed the final two months of last season with a right-shoulder strain and was sidelined for part of spring training by shoulder soreness, more than held his own in his first big-league start this year.
Pettibone lasted five innings, allowing two runs, one earned, on eight hits while striking out five and walking one. He threw 80 pitches, 49 for strikes.
"I felt pretty good," Pettibone said. "Early on it was more of me trying to get in control of my emotions, settling down, and not rushing."
With the bases loaded and two outs in the second, the Marlins scored their first run when first baseman Ryan Howard dropped a throw from Rollins on a Marcell Ozuna grounder to short.
The next batter, Giancarlo Stanton, hit a 3-0 pitch up the middle, where Utley fielded the ball behind second base and flipped it to Rollins for the apparent force. Second-base umpire Gary Cederstrom, however, called Ozuna safe at second and two runs scored.
The Phillies successfully appealed, with the replay showing Rollins beat Ozuna to the bag. The review took 2 minutes, 27 seconds.
"I knew I beat him to the bag," Rollins said.
The Phillies made it 4-1 on an RBI double by Utley down the first-base line and a run-scoring single by Howard in the third.
Stanton made it 4-2 in the fifth inning when he crushed a 1-1 change-up from Pettibone for a solo home run into Ashburn Alley that was measured at 470 feet.
In the seventh, Stanton tied the score with a two-run, line-drive homer to left off Justin De Fratus.
