Dustin Pedroia drove in four runs and had three of Boston's season-high 20 hits, and Ryan Dempster took advantage of an early cushion that kept getting bigger for the Red Sox in their 11-4 victory over the Colorado Rockies on Tuesday night.
Mike Napoli added two RBIs and Jacoby Ellsbury, Daniel Nava and Jose Iglesias joined Pedroia with three hits apiece as the Red Sox gave Dempster an abundance of offense after scoring just two runs in his previous two starts combined.
Rockies starter Juan Nicasio (4-4) lasted just 2 and a third innings, giving up 7 runs. Michael Cuddyer went 2-for-5 and extended his hitting streak to 22 games.
Dempster (5-8) allowed two runs and six hits over six innings, leaving with an 8-2 lead and picking up his first victory since June 9.
