The Tigers activated Greene (hamstring) from the 10-day injured list, and he's starting in left field and batting cleanup Tuesday against the Twins.
The 25-year-old outfielder has been sidelined since suffering a hamstring string Aug. 12 but is now back with the Tigers for the final month of the season. Greene went 1-for-6 with two walks in two rehab games and will look to shake off the slow start to August that saw him bat .214 (6-for-28) with two extra-base hits and 12 strikeouts.
