Halladay ended Jorge Cantu's major league-record streak of 10 games with at least one hit and one RBI, and Dan Uggla hit a solo shot for Florida.
Pitching in a steady rain, Halladay (3-0) shrugged off the conditions and allowed two runs and eight hits. He threw 100 pitches, struck out four and didn't walk a batter.
Florida took advantage of three infield hits to score four runs off David Herndon in the ninth before Ryan Madson got the two outs for his third save in three tries. Madson retired Cantu on a fielder's choice grounder with two runners on to end it.
