With only three days left in the 2013 baseball season, most of the playoff teams have been set and we can look back on a wild ride. Miguel Cabrera flirted with his second straight triple crown, the Dodgers won an astonishing 42 out of 50 games in one stretch, and Alex Rodriguez did his best to make sure the last handful of people who didn’t find him completely unlikeable were converted.

But as we can now see which cities will be celebrating October baseball, here’s a quick look at the baseball postseason from an equities perspective. Here are your baseball cities and the biggest public companies located in each.

Detroit

Yes, there are still things located in Detroit other than cars and misery. The Detroit Tigers, for instance, clinched their third-straight American League Central Division on Wednesday night with a 1-0 victory over the Minnesota Twins, making them the first team ever to clinch their division with a 1-0 road win.

And in terms of public companies, Detroit’s no mystery. It is as it’s always been and General Motors (GM) and Ford (F) are the two biggest companies on the block. Rounding out the traditional “big three” is Chrysler, which announced that it had filed the paperwork for an IPO earlier this week.

Boston

The Red Sox have been the story of the American League this year, going from worst to first after rising from the ashes of Bobby Valentine. Now, in their first year under new manager John Farrell, the Red Sox have clinched the AL East despite tough competition all year.

The Greater Boston area has long been a science and technology hub, with companies like Boston Scientific (BSX) . It’s also a center for the financial industry, with Fidelity Investments, and the Hanover Insurance Group, Inc. ($THG).

Oakland

Billy Beane’s worked his magic again and the Oakland A’s are back in the post season. And Oakland’s grateful, especially given how bad the Raiders look thus far. The city of Oakland has the headquarters for Nestle’s ($NESN) ice cream subsidiariesHaagen-Dasz and Dreyer’s. It’s also home to cleaning conglomerate Clorox (CLX) .

AL Wild Cards

While it’s not certain yet, the most likely wild card teams in the American League will be the Cleveland (somewhat racist nickname) Indians and the Tampa Bay (not the Devil) Rays. Cleveland is home to Olympic Steel (ZEUS) and its delightful ticker, as well as Sherwin-Williams Company (SHW) , KeyCorp (KEY) , and DDR Corp. (DDR) . It’s also the original location of Standard Oil. Tampa, which is the name of the city despite both its major sports teams referring to Tampa Bay, has TECO Energy (TE) , Outback Steakhouse owner Bloomin’ Brands (BLMN) , and Sykes Enterprises (SYKE) .

Atlanta

Despite everyone and their mother picking the Washington Nationals to win the National League East as Stephen Strasburg struck out every batter he faced and golden angels swooping down to carry each Bryce Harper drive into the stands, the Nationals are almost ten games out of first and Atlanta’s had the division basically wrapped up since the end of May. The Braves have combined a solid rotation with a flame-throwing bullpen and cruised into the postseason. Atlanta, meanwhile, is home to the Coca-Cola Company (KO) , founded in 1886 and now worth over $170 billion. It’s also the city Equifax (EFX) , The Home Depot (HD) , and Delta Airlines (DAL) .

St. Louis

It’s not final yet, but the St. Louis Cardinals certainly seem set to beat out the Pittsburgh Pirates and win the NL Central. The Cards have won the World Series twice in the last six years, but that’s apparently not enough for them as they’re back at it again this year. St. Louis, meanwhile, is home to the single company that might benefit the most from the sport of baseball, Anheuser Busch InBev (BUD) . You’ll also find the headquarters for Arch Coal (ACI) , Stifel Financial Corp. ($SF), and Wachovia Securities (which merged with Wells Fargo ($WFC) in 2008).

Los Angeles

The Dodgers appeared to be out of contention in late May. Ravaged by injuries and poor performance, Dodgers fans seemed destined for another year having to watch ace Clayton Kershaw continue to be the best pitcher in the National League and have in not matter. That was before Cuban phenom Yasiel Puig was called up and the Dodgers transformed into the hottest team in baseball.

Los Angeles is a city most directly associated with the entertainment industry, but it’s actually the home to some 23 Fotune 500 companies. Sure, you have the Walt Disney Company (DIS) and DirecTV (DTV) . But you also have the Northrop Grumman Corporation (NOC) , Ingram Micro (IM) , and Health Net Inc. (HNT) .

NL Wild Cards

Unlike the American League, the National League wild card has been settled for months. And both teams are in the same division. The Cincinnati Reds and Pittsburgh Pirates have been duking it out with the Cardinals all summer. For the Reds, it’s certainly nothing new to be headed to the postseason in October, but the Pirates are enjoying their first trip to the playoffs since Barry Bonds had a normal-sized head. In fact, this season represents the Pirates first winning season in over two decades.

Cincinnati is now the home to $200 billion consumer goods conglomerate Proctor & Gamble (PG) as well as American Financial Group ($AFG), and Cintas (CTAS) . Pittsburgh, meanwhile, has always been known for the steel industry and remains the home of United States Steel (X) as well as several other of America’s most recognizable corporations like the H.J. Heinz Company ($HNZ), Alcoa ($AA), and PNC Financial Services Group ($PNC).
