After the game the Marlins optioned OF JordanBrown to Triple-A New Orleans and 1B Casey Kotchman (hamstring) will be reinstated from the 60-day disabled list on Monday.
Pinch-hitter JordanBrown hit a two-run double, and Ed Lucas and Jeff Mathis each drove home a run in the pivotal seventh as the Marlins won for the third time in 19 games.
One of them, Frank Jordan, had been beaten by Mr Brown four years earlier after scuppering his credibility by inviting two radio disc-jockeys to strip off and join him in the shower.
The home side offered greater resistance when they came out to bat for a second time, with Michael Carberry and Brown sharing a stand of 63 before Brown, on 30, hooked a ball from Chris Jordan to Matt Nicholson at long-leg.
