Greinke started Wednesday's game against Pittsburgh on three days' rest as the Brewers needed a win to lock up the No. 2 seed in the NL.
The decision to bring Greinke back on short rest is probably due to his home success. He went 11-0 with a 3.13 ERA at Miller Park during the regular season, and the Brewers won all 15 of his starts at home.
Greinke was 5-6 with a 4.70 ERA on the road.
