Olsen (2-0) struck out three and did not walk a batter. He threw 84 pitches, 62 for strikes.
Josh Willingham hit an RBI triple for the Marlins. He also stole two bases and scored once. Mike Jacobs added a pair of doubles for his fifth straight multihit game.
Atlanta starter Jair Jurrjens (1-2) gave up two runs and four hits in six innings.
Willingham scored the first run in the fourth when he walked with two outs, stole second and came home on Jacobs' first double. That snapped a streak of 10 consecutive Florida runs coming off homers.
The Marlins increased their lead to 2-0 in the sixth when Willingham tripled to drive home Dan Uggla, who led off with a double. Florida scored twice in the eighth inning when Braves reliever Will Ohman walked pinch-hitter Wes Helms and Hanley Ramirez with the bases loaded.
The Braves' only threat against Olsen came in the sixth when Kelly Johnson and Yunel Escobar opened the inning with singles. But Olsen got Chipper Jones and Mark Teixeira to fly out before Jeff Francoeur grounded out to end the inning.
