2007: Win (4-0)
The Red Sox steamrolled the Los Angeles Angels in the first round of the playoffs and faced off against the Cleveland Indians in the ALCS. The Sox won Game 1, but lost the next three to leave them in a 3-1 hole entering Game 5.
Josh Beckett put the team on his back, pitching eight innings and allowing just one run with 11 strikeouts to send the series back to Boston. The Sox, now comfortable back at home, demolished the Indians over the next two games, winning Game 6, 12-2, and Game 7, 11-2, to win their second American League pennant in four seasons.
In the World Series, the Red Sox played the Colorado Rockies, who, after winning 14 of their final 15 games just to force a one-game playoff for the wild card, swept through the Philadelphia Phillies and the Arizona Diamondbacks to win the NL pennant. After sweeping both series, the Rockies had a long layover before playing in the World Series, which may have led to their ultimate downfall, as Boston won Games 1 and 2 in Boston.
When the series moved to Colorado, the Red Sox slammed the Rockies 10-5 in Game 3, giving the Sox a chance to sweep their second World Series of the new millennium. Up 4-1 in Game 4, the Rockies rallied to cut it to 4-3 in the bottom of the eighth inning, setting up Jonathan Papelbon for a chance to save the game and win the World Series in the ninth. The future Red Sox franchise leader in saves would deliver, striking out the final batter to give the Sox their second world championship in four years, becoming the first MLB team to win two World Series titles in the 21st century.
