Who can clinch a playoff spot next?

Atlanta Braves

The Braves are on the verge of becoming the first team to punch a ticket to this year's MLB playoffs. Atlanta can clinch a postseason berth with a win on Sunday.

What are this October's MLB playoff matchups as it stands now?

American League

Wild-card round: (6) Blue Jays at (3) Twins, (5) Mariners at (4) Rays

ALDS: Twins/Blue Jays vs. (2) Houston, Rays/Mariners vs. (1) Orioles

National League

Wild-card round: (6) Diamondbacks at (3) Brewers, (5) Cubs at (4) Phillies

NLDS: Brewers/Marlins vs. (2) Dodgers, Phillies/Cubs vs. (1) Braves

Breaking down the AL race

Despite spending a majority of the season atop the AL East, the Rays find themselves the top wild-card team in the American League after the Orioles took sole possession of first place in the division in late July. Two other members of the AL East are still in playoff contention, although the Boston Red Sox's chances are slowly dwindling. The Toronto Blue Jays, on the other hand, are locked in a close battle for the final wild-card spot.

Their competition? A Texas Rangers team that, like the Rays, led the division for more than 100 days this season but now finds itself fighting for a postseason berth. The Mariners, who usurped the Rangers atop the AL West, and Houston Astros are now vying for the division title, while the Minnesota Twins look to be a lock as the lone AL Central representative in October.

And what about when these teams get to the playoffs? Here's what their chances are for every round of the playoffs:

Breaking down the NL race

The divisional races in the National League aren't quite as close as the ones in the AL, as both the Braves and Dodgers have all but locked up the NL East and NL West, respectively. The Milwaukee Brewers have long held first place in the NL Central, but the Cubs are within striking distance of replacing them.

Now, the wild-card race is where it gets exciting. While the Phillies and Cubs have strong holds on the first two wild-card spots, four teams -- the Arizona Diamondbacks, Cincinnati Reds, Miami Marlins and San Francisco Giants -- are within a few games of each other for the final spot. Miami and Cincinnati are the big surprises, as neither team was thought to be a playoff contender entering the season. Meanwhile, Arizona finds itself in the wild-card hunt despite having led the Dodgers atop the division for parts of the first half.
