And Jean Segura missed his eighth straight game because of a strained right hamstring. He entered leading the NL with 44 steals but Mets outfielder Eric Young Jr. tied him by swiping two bases.
Young scored on Daniel Murphy's groundout in the third.
"It's going to be fun," Young said of challenging Segura for the title. "Regardless of the results, it's been fun the whole way, this whole season."
Jim Henderson gave up a homer, affirmed by video review, to pinch-hitter Josh Satin before striking out three for his 27th save.
"Henderson was a little bit off today," Roenicke said.
The Brewers scored four times in the second in front of a sparse crowd that barely made any noise except for the startled "oohs" when Wright was hit.
Gee walked Khris Davis to start the inning. Caleb Gindl singled to left-center and, after an out, Juan Francisco drove in a run with a slow-rolling grounder up the middle. Jeff Bianchi added another RBI with a soft blooper to left. Scooter Gennett capped the inning with a two-run single.
Lifted for a pinch hitter in the sixth, Gee gave up four runs and seven hits. He walked two in finishing the season at 199 innings, an encouraging sign after missing much of last season following surgery to remove a blood clot from an artery in his pitching shoulder.
