Steve Pearce smashed two home runs as the Boston Red Sox romped to their ninth World Series crown on Sunday, pounding the Los Angeles Dodgers 5-1 with a ruthless display of hitting to clinch the Major League Baseball championship with two games to spare. Pearce's double-blast sandwiched home runs from Mookie Betts and J.D. Martinez to seal a 4-1 victory in the best-of-seven match-up as the Dodgers' quest for a first World Series title since 1988 ended in disappointment. The 35-year-old Pearce, who supported the Red Sox as a boy, only joined the club in June after an 11-year career in the Majors.
