Usually I'm on top of uniform/logo/color changes, but I've also been “away” for the last two weeks, so I missed a “change”.
The Mariners apparently announced earlier this month that they will be wearing their teal throwbacks as an alternative uniform next season up to twice a week at home:
(via MLB.com, example of the color)
Overall, I'm for this. When you think about it, once the Devil Rays became the Rays, the amount of green, or similar to green colors worn by Major League teams really dropped. Outside of the green trims for the Mariners, and the Oakland Athletics, I'm pretty sure no other team has green as a major color in their uniform design (not including the Padre camo look).
This green/blue/teal/something is also unique. When baseball teams wear odd colors, it is at least refreshing for the eyes. Uni Watch blog is saying that this uniform change will move the Mariners navy blue alternates to the road.
EDIT: I'm an idiot. I forgot the one team in our division that “wears” green: the Marlins. Thank you mysterious commenter for pointing that out.
The marlins have green, dont they?? 🙂
Wow. You are so right. That's embarrassing that I forgot that.
