MIAMI, July 10 (UPI) -- Mike Cameron's two-run homer sparked a fourth-inning Florida rally Sunday that carried Florida to a 5-4 victory over Houston and a four game sweep.
Cameron, obtained in a July 5 trade with the Red Sox, erased a 3-1 Houston lead with a home run after Mike Stanton had led off the fourth with a walk.
John Buck then singled, went to third on Emilio Bonifacio's hit and come home on Omar Infante's sacrifice fly, putting the Marlins ahead for good. Gaby Sanchez capped the rally with run-scoring double.
Chris Volstad (5-8) earned the victory, yielding three runs on seven hits through six innings, walking one and striking out five.
Four Marlins relievers combined for two innings of scoreless relief and Leo Nunez nailed down his 25th save as Florida posted its season-best fifth straight win.
Houston's Wandy Rodriguez (6-6) was tagged with the loss, allowing five runs on five hits before exiting after 5 1/3 frames.
Hunter Pence socked a solo homer and Ben Wallace added two hits, including a two-run double, as the Astros lost for the 17th time in 20 games.
