The 2018 Major League Baseball postseason ran from October 2 to October 28, culminating in the Boston Red Sox defeating the Los Angeles Dodgers in five games to win the World Series—their ninth championship, tying the Oakland Athletics for third-most all-time. The American League was historically strong, featuring three 100-win teams: the Red Sox (108), Houston Astros (103), and New York Yankees (100). The playoffs opened with thrilling wild-card games, as the Colorado Rockies upset the Chicago Cubs in a 13-inning duel, while the Yankees blew out the Oakland Athletics. In the AL Division Series, the Red Sox eliminated the Yankees in four games, highlighted by a stunning 16-1 rout in Game 3—the Yankees' worst postseason loss ever—while the Astros swept the Cleveland Indians. The National League saw the Atlanta Braves make their first playoff appearance since 2013 (starting a seven-year streak), alongside the Dodgers' sixth straight appearance. Ultimately, the Red Sox's championship capped a dominant season, overcoming their historic rivals to claim the title.
