Lopez (4-4) allowed three runs on three hits and a walk in a third of an inning to take the loss against the Tigers on Sunday.
Lopez entered Sunday's game to preserve a tie in the top of the ninth inning, but he gave up a home run to lead off the frame before allowing two more runs to come across prior to his removal. The right-hander allowed at least two runs in five of his last six outings of the regular season, and he'll likely pitch out of the bullpen during the playoffs.
