World Series 2021: Atlanta Braves vs. Houston Astros by the numbers

The 2021 MLB season all comes down to this.

On Tuesday, the Atlanta Braves host the Houston Astros in Game 1 of the World Series on FOX.

The Braves punched their ticket by knocking out the reigning world champion Los Angeles Dodgers in the NLCS 4-2. On the other side, the Astros rallied back with three straight wins after falling behind 2-1 to the Boston Red Sox in the ALCS, claiming their spot on baseball's biggest stage.

Atlanta leads the all-time series 3-2, with two of those wins being sweeps (1997, 2001). This will be the teams' first time playing each other in a best-of-seven series.
