MIAMI -- The Atlanta Braves scored seven runs in the first inning and cruised past the Miami Marlins 12-2 on Tuesday night at Marlins Park.

First baseman Freddie Freeman and shortstop Andrelton Simmons each went 3-for-5 with two RBIs to lead Atlanta. Third baseman Chris Johnson also added two hits and two RBIs.

Right-hander Mat Latos, who made his debut with the Marlins, lasted just two-thirds of an inning as Miami's starter, allowing six hits, two walks, one wild pitch and seven runs, all earned. His ERA is 94.50, and he was booed by many of the 17,483 fans in attendance as he left the field.

Atlanta (2-0) will go for a sweep against Miami (0-2) on Wednesday.

Tuesday's win went to left-hander Alex Wood (1-0), who went five innings and allowed two runs. He worked out of a bases-loaded, no-out jam in the first and cruised until he gave up two runs in the fifth. It was the second straight game Miami failed to score with no outs and the bags loaded.

Braves relievers Brandon Cunniff and Cody Martin -- both right-handers -- made their MLB debuts. Cunniff pitched one scoreless inning. Martin was scoreless for two innings. Another rookie, Juan Jaime, closed out the game, pitching a scoreless ninth.

Atlanta batted around in the first inning and jumped out to a 7-0 lead. Lead-off man Eric Young walked and stole second to get things going, and the Braves got RBI hits from right fielder Nick Markakis (single), Freeman (double), catcher Christian Bethancourt (double), Johnson (double), Simmons (single) and Young (single).

Of the two outs Latos recorded, one was on a sacrifice bunt.

Miami had a chance to get back in the game in the bottom of the first inning, loading the bases with no outs. But the Marlins failed to score after clean-up hitter/first baseman Michael Morse struck out and third baseman Martin Prado bounced into a double play.

The Marlins scored twice in the fifth to cut Atlanta's lead to 7-2. After a leadoff walk by shortstop Adeiny Hechavarria, Miami got RBI from pinch-hitter Donovan Solano, who tripled to right-center, and second baseman Dee Gordon, who grounded out.

NOTES: The only change in either lineup from Monday was Atlanta sitting switch-hitting 3B Alberto Callaspo in favor of righty-hitting 3B Chris Johnson. The Braves plan to rotate those two all season depending on pitching matchups. ... The Braves have five rookies on their roster: 2B Jace Peterson, LHP Andrew McKirahan, RHP Brandon Cunniff, RHP Cody Martin and RHP Juan Jaime. In Monday's Opening Day win, Peterson got his first major league hit, put down a successful sacrifice bunt and scored a run. ... Veteran OF Cameron Maybin, acquired from San Diego on Sunday, made his Braves debut Monday, going 0-for-1 off the bench. ... Lost amid Miami's loss Monday were the two scoreless innings of relief pitching by the duo of LHP Mike Dunn (struck out the side) and RHP A.J. Ramos (two strikeouts).
