ATLANTA -- The Braves put together a two-run rally in the bottom of the ninth off Twins reliever Matt Capps to tie the game, and Mauro Gomez belted a two-run walk-off homer in the 10th to give Atlanta a 4-2 victory Tuesday at Turner Field.

Twins right-hander Nick Blackburn made quick work in his final spring tuneup, facing the minimum 12 hitters and needing just 30 pitches over four scoreless innings.

Blackburn, who will start Sunday in the finale of the opening three-game series at Toronto, benefited from two double plays. He allowed a single in the first to Braves leadoff hitter Martin Prado and walked Brian McCann to start the second inning. Both times, the Twins turned two.

The scoreless stint lowered Blackburn's spring ERA to 1.73 over seven starts. He pitched six scoreless innings in his previous outing against the Philadelphia Phillies.

The Twins scored in the second inning when Michael Cuddyer singled to left field. The ball was booted and allowed Jim Thome, who had doubled, to score. Joe Mauer had a sacrifice fly in the third inning after a walk by Denard Span and single by Tsuyoshi Nishioka.

Atlanta went with all relief pitchers, each getting an inning. Peter Moylan pitched a perfect fourth inning, striking out two.

Braves manager Fredi Gonzalez used what could be his Opening Day lineup in Washington on Thursday.

Up next for the Braves: Rookie right-hander Brandon Beachy, who used a 1.13 ERA in four Grapefruit League outings to win a spot in the Atlanta rotation, is scheduled to face the Twins on Wednesday at Turner Field on MLB.TV at 12:05 p.m. ET in the final exhibition game for both teams.

Up next for the Twins: Scott Baker will start for Minnesota. The right-hander was 2-3 with a 3.38 ERA in five Grapefruit League starts.
