The Marlins went on to beat the Braves, 5-4, in 12 innings at Turner Field.
As it turned out, Cameron's lone at-bat was his final moment in a Marlins uniform.
After the game, the club announced that it had released the 17-year veteran center fielder.
The Marlins are dealing with a number of outfield ailments. Left fielder Logan Morrison returned to South Florida to get an MRI exam on a bruised right knee, and he isn't expected to play until Friday, at the earliest.
Mike Stanton, who had the game-winning, pinch-hit RBI single in the 12th inning on Monday, is not ready to play on a daily basis in right field. Stanton has also been bothered by a tight right hamstring.
In addition to the hamstring injury, Cameron has also dealt with a sprained left wrist and sore knees.
With a limited number of healthy outfielders, the Marlins may be looking to call up either Chris Coghlan, who has been at Triple-A New Orleans, or reinstate Scott Cousins, who is on the 60-day disabled list with a back injury.
The 38-year-old Cameron has hinted that he may retire after the season.
A former Gold Glove Award-winning outfielder, Cameron broke in with the White Sox in 1995, and he opened this year with the Red Sox before being traded to the Marlins on July 5 for future considerations.
In 44 games with Florida, Cameron hit .239 with six homers and 18 RBIs. He is a career .249 hitter with 278 homers and 968 RBIs.
