The Mariners uniforms are making news for the second straight offseason.

The Seattle Mariners are headed for a very interesting uniform-related distinction in 2027 if things continue the way they are.

On Monday, the Tampa Bay Rays announced that they were bringing their road gray uniforms back in 2027, and they are paying homage to their original "Devil Rays" uniform. The uniforms will read "Tampa Bay" on the front, as a tribute to the organization's commitment to their home area - and its history.

With this news, the Mariners are now the only American League team without a "road gray" uniform. Of course, things can change over the offseason, but that's the situation for now.

The Milwaukee Brewers, as of this season, also don't have a road gray uniform in the National League.

Why is this?

Major League Baseball has worked with the "4+1" rule for a few years now, meaning that each team is allowed to have four uniforms in their set, plus one "City Connect" uniform.

As a result, the Mariners have the home white uniforms, the navy alternates, the teal alternates, the Steelheads alternates, and the allotted "City Connect."

This rule is the reason why the Mariners had to dump the Sunday cream alternates in the last offseason. They wanted to make room for the Steelheads uniforms, so something had to go.

The Rays had been using a white uniform, a Devils Rays white alternate, a navy alternate and a power blue alternate. It's unclear which one is going.

Could the Mariners change up their uniforms again?

Sure they could, and some fans are clamoring for it. The M's are slated to get new "City Connect" uniforms in 2027, so there will be some natural change, but there's always a chance that they could update to a fresher look in general.

The home white uniforms have remain unchanged since the early 1990s and are now more than 30 years old.

Also in the news for the Mariners

After allowing a solo home run and a walk in the bottom of the ninth inning of Sunday's 2-1 win against the Rockies, closer Andres Munoz left the game with manager Dan Wilson and the medical staff.

Munoz left a game in Washington in June with back problems, something he's dealt with before, but this injury was attributed to his left knee, according to Ryan Divish of the Seattle Times

Munoz has had an up-and-down year for the Mariners, recording 28 saves, but blowing 10 others. He has a 4.24 ERA in total.

The Mariners, 73-83, will take on the Houston Astros for the start of a two-game series on Tuesday at T-Mobile Park. The Astros are one game behind the Texas Rangers in the American League West race.
