The first half of the Major League Baseball season is almost over. And big market teams are leading the way:

Of the top 10 teams in playoff position, seven teams come from the top seven North American markets by population figures, according to the Census Bureau and Canada population sources. They are, 1) the New York Yankees and New York Mets, 2) Los Angeles Dodgers, 3) Chicago Cubs, 5) Houston Astros, 6) Toronto Blue Jays and 7) Philadelphia Phillies.
The three other teams in the top 10? Detroit, Tampa, and Milwaukee. According to one source, they rank as the #17, #24, and #outside of the top 50 most populous metropolitan regions.
A few other thoughts about this list:
- Mexico City is the largest North American market. Of course, MLB only has teams in the US and Canada (one team).
- Missing teams from the other largest markets: Dallas-Fort Worth, Atlanta, Washington, D.C., Miami.
- Metropolitan population may not compare exactly with market size. This listing of MLB market sizes has a slightly different order.
- All seven teams in the big markets play in stadiums in their city (not in the suburbs).
- The argument in baseball tends to go that the teams in the largest markets have the most money to spend. This could be connected to local media deals (the LA Dodgers with the biggest) or perhaps owners from certain places having funds or lots of fans attending games in certain places.
- But having money does not necessarily guarantee being in a bigger market or winning a World Series. One analysis:
Since 1995, 48% of the champions and 38% of the contestants in the World Series have had top 5 payrolls. 93% of the champions and 83% of the contestants have been in the top half of payroll. Only two low-payroll teams have won it all — the 2002 Anaheim Angels and the 2003 Florida Marlins. It has been two decades since that has happened.
The list of losing World Series teams in the bottom half of payroll for the season includes the 2007 Rockies, 2008 and 2020 Rays, 2010 Rangers, 2014 Royals, 2015 Mets, 2016 Indians, and 2023 Diamondbacks.
