MLB standings 2021: Updated playoff bracket, magic numbers as of Sept. 12

The 2021 MLB season is rapidly winding down, and as it nears its finish several postseason races have drawn most of the focus.

All but two divisional races appear locked up. The Braves surged into first place in August and are holding to the top spot early in September with the Phillies and Mets not too far behind them. The Giants have quietly been the best team in baseball  for most of the season, yet find themselves holding off an incredibly talented Dodgers squad in the NL West.

Both the races for the wild card look to be fights to the finish. In the American League, the Red Sox and Yankees entered September clinging to the top two spots, but have faced pressure from the Blue Jays, Mariners and Athletics. The team that finishes second in the NL West is all but guaranteed to wrap up the first wild card, but the second spot is wide open as the Reds, Padres, Phillies, Cardinals and Mets are all within striking distance of one another.

MLB magic numbers for 2021
