Apparently they saw something out of the 28-year-old, with a career .218 batting average, that no one else could.
In his Astros debut on Friday night, Greene saw limited action as a pinch runner in the bottom of the ninth. With Houston down 3-2, the newcomer stole second, his 10th of the season, and then took third as a result of a wild pitch by Brewers' closer John Axford.
Greene was then driven home by Steve Pearce to even the game up at three a piece. Two batters later, Pearce scored the game-winning run.
It would be hard to follow up his debut in which he was key in his new team's come from behind win, but Greene decided he would try anyways.
