Todd Helton homered, doubled and drove in three runs in his final game at Coors Field, but the Boston Red Sox used Will Middlebrooks' two homers and career-high seven RBIs to beat the Colorado Rockies 15-5 Wednesday night.
Helton also had a sacrifice fly in his Colorado farewell. The first baseman is retiring at the end of his 17th season with the Rockies.
Middlebrooks hit his third career grand slam and a three-run homer. The Red Sox, who clinched the AL East title last week, moved two games ahead of Oakland for the best record in the league.
