If the Tigers reach the postseason, they can look back at their dominance of the Twins as a determining factor.
Detroit won both games of the day-night doubleheader Thursday, pulling away to a 9-2 win in the day game, then holding on for a 4-2 win in the evening game.
The lopsided season series is now complete, with the Twins going 4-15 against the Motown Nine.
"Frustrating. Embarrassing," Twins second baseman Brian Dozier said. "If I was any smarter, I'd give you more words."
That dominance includes the Twins losing all nine home games to the Tigers. The only other time in club history they were swept at home by a division opponent was 1979, when the Rangers went 6-0 against them in the old AL West.
Dozier had an up-and-down day himself, smashing his 42nd home run in the first game but watching hitting streak end at 24 in the nightcap, thanks to Justin Verlander and the Tigers bullpen.
The Twins were down 1-0 in the first inning of the first game when Dozier drove an Anibal Sanchez pitch into the second deck to tie the score.
Every time Dozier connects he seems to reach another milestone. The home run pulled him within one of Mark Trumbo for the major league lead.
