The Tigers won their third straight and pulled within a half-game of Toronto for the second AL wild-card spot. The Blue Jays lost at Boston 5-3.
The regular season is scheduled to end Sunday, but the Tigers might need to play beyond that. They were rained out against Cleveland this week and would have to make up that game if it impacts their playoff chances.
Daniel Norris (4-2) gave up one run, five hits, two walks and struck out eight in 6 2/3 innings.
The Braves, playing their final series at Turner Field before moving north to the suburbs next year, had won 10 of 11. Matt Wisler (7-13) was chased in the fifth when James McCann's RBI single made it 5-0.
