Tacoma Rainiers. On September 4, Green was called up to the Major League club. He appeared in six games for the Mariners and had seven at-bats, without recording a hit. Boston Red Sox After spending the 2008 season back in the Yankees minor league system, he signed a minor league contract with an invitation to spring training with the Boston Red Sox, and won a spot on the opening day roster. After teammates Julio Lugo and Jed Lowrie were both placed on the disabled list early in the season, Green became the Red Sox's starting shortstop. After Lugo returned from the DL, he and Green were on a day-to-day playing rotation. On June 21, 2009, Green hit a first pitch walk-off home run to lead the Boston Red Sox to a 6-5 victory over the Braves.

During his two innings of scoreless relief, Green walked 3 batters and allowed no hits and no runs on 35 pitches. He topped out at 90 mph on his fastball. He also threw one slider in the game.
