The MLB franchise New York Yankees played its first game in 1903 as New York “Highlanders”
That's interesting! Didn't they originally play as the Orioles too? 
Yeah but no relation to the modern Baltimore Orioles
It's funny how most MLB teams are named after people or types of people, and how many teams are named after birds. I wonder why. 
But case of Yankees is 1n 1903, Frank Farrell and Bill Devery purchased the franchise after it ceased operations and moved it to New York City, renaming the club the New York Highlanders. The Highlanders were officially renamed the New York Yankees in 1913
I didn't realize how much the Baltimore Orioles (the ones currently in Baltimore, not the original team) moved around before settling in Baltimore. Milwaukee, St. Louis, they were everywhere. 
The MLB  has some of the richest sports teams in the world, with teams like the New York Yankees being valued at over 4$ billion money is the major factor or all teams to move around
Wow, that's a lot of money. The Astros are worth over a billion dollars, and they are not nearly as good or well-known  a team. 
When determining the most successful baseball teams in the MLB and indeed the best teams in the world, the World Series will give us the answer.
So it seems like the team that has won the most World Series would be the 'best', but there are some teams that are much newer than others, like the Marlins. They've won twice but have only been around since the 90s
