(The Sports Xchange) - The Colorado Rockies did their part Sunday to keep the Los Angeles Dodgers from celebrating a division title, completing a three-game series sweep with a 12-5 victory. Rockies third baseman Nolan Arenado hit a go-ahead, three-run homer and had a career-high five RBIs, increasing his major-league leading total to 126. The Dodgers' magic number to clinch the National League West remained at two after the San Francisco Giants won at Oakland.
