The best hitter in the Boston Red Sox lineup when there have been opportunities to drive in runs has been the one guy guaranteed to step to the plate at least once each game with the bases empty. That would be the leadoff man, Andrew Benintendi.
The 24-year old left fielder enters the day leading the majors with a whopping .524 batting average with runners in scoring position (minimum 25 plate appearances). Benintendi is 11-for-21 with four doubles, a triple, and a home run in those situations while ranking third in the majors with a 1.
