MIAMI — The Atlanta Braves made themselves at home all weekend at Marlins Park, including when Evan Gattis put a dent in the home run sculpture Sunday. Gattis broke a ninth-inning tie with a two-run homer, newcomer Shae Simmons made another key contribution and Atlanta completed a three-game sweep by beating Miami 4-2. "We played about as good a series as we've played in a while," Atlanta manager Fredi Gonzalez said.
