The first-place Boston Red Sox doubled the Houston Astros 6-3 on Saturday to clinch their second straight East Division title in a battle between two American League heavyweights. The Red Sox and American League West Division champion Astros will meet in game one of the first round of the playoffs on Thursday in Texas. This marks the first time since division play began in 1969 that the Red Sox have won back-to-back American League East crowns.
