Answer
Boston Red Sox pitcher Daisuke Matsuzaka was a key member of the team's 2007 World Series victory. The Japanese right-hander started Game 3 of the series against the Colorado Rockies and pitched 5.2 innings, allowing only one run and striking out six batters. Matsuzaka's performance helped the Red Sox to a 10-5 victory and a 2-1 lead in the series.
