Teams have many different uniforms they switch out. Many teams will change them periodically. Then, years later, they will bring them back.
One interesting fact, when the team is home, the name on the front of the jersey is Mets.
When they are in their road uniforms, it says New York across the front.
That is how you can tell if it is a home or road uniform.
I found that really interesting.
I hadn't paid attention yet and now I'm going to pay attention to these details on the uniform.
