MILWAUKEE -- Brewers infielder Taylor Green hit his first career home run in Wednesday's win over the Cubs, then made a friend."His name's Mike," Green said. "He's a great guy." Mike was sitting in the right-field bleachers at Miller Park and grabbed Green's eighth-inning, three-run shot, the cherry on top of an 8-0 Brewers win. Green, 25, met with the fan outside the clubhouse after the game and received the baseball as a memento. Mike didn't ask for anything in return. "I gave him a bat, though," Green said. Green's first career homer came in his 89th at-bat -- 52 this year after 37 at-bats in 2011. Twice a Brewers Minor League Player of the Year, Green's playing time this season has been tied directly to the Brewers' run of injuries. He's played some first base in place of Mat Gamel, lost for the season to a knee injury. And he has manned third for Aramis Ramirez, who missed a third straight start Wednesday with a quadriceps strain. "It's kind of bittersweet to get your opportunities like this, but it's part of the game," Green said. "You have to be ready for your opportunity." That opportunity came off the bench on Wednesday against former Cubs closer Carlos Marmol, whose season-long struggles have moved him to a middle-relief role. "He's got a good slider, and the one before I fouled it right off my shin, so I kind of thought he might be throwing it again," Green said. "He did. I was lucky enough to put a good swing on it." Green has a souvenir baseball to show for it.
