Name the northernmost and southernmost cities having teams in major league baseball (whether in the United States or Canada).

Major League Baseball spans a vast geographic area across North America, from the Pacific Northwest to the tip of the Florida peninsula. Considering all 30 teams, the city that holds the distinction for the highest latitude is Seattle, Washington. Home to the Mariners, T-Mobile Park sits well above the 47th parallel north, making it the northernmost stadium in the league, including all Canadian franchises. This puts it significantly further north than other cities like Minneapolis or Toronto, which might seem contenders at first glance.

At the opposite end of the spectrum, venturing far south into the subtropical climate, we find the southernmost MLB city: Miami, Florida. The home of the Marlins, loanDepot Park, is situated just above the 25th parallel north. This puts it at a lower latitude than any other team in the continental United States, and indeed, the entire league. Its position on the southeastern coast makes it a unique outlier in terms of geographic location for professional sports in North America.

The considerable distance between these two coastal cities highlights the expansive reach of Major League Baseball. From the often-rainy, temperate climate of Seattle to the sunny, humid conditions of Miami, the league truly covers a diverse range of North American landscapes and weather patterns, a testament to its widespread appeal and entrenched presence across the continent.
