This season has been one to celebrate, especially for the Mariners.
The team has been celebrating its 40th anniversary the entire season, and Saturday night hosted something extra special when the Astros came to town.
It was "Turn Back the Clock Night" at Safeco Field and the team was celebrating 1977 -- the first season of the franchise's creation.
And while the Mariners finished sixth in the American League West that year, the one thing they had was awesome uniforms when they played at the Kingdome.
In addition to the throwback uniforms, the fans and staff paid tribute to the disco era.
Mariner Moose himself was decked out in his Saturday Night Fever disco suit accompanied by some psychedelic ladies on his arms.
And so did Orbit...
Speaking of psychedelic -- this fan didn't waste any time getting his groove on sporting a disco ball around his neck.
Fans also participated by showing their flashback photos from their times watching the Mariners including some old school clothes and feathered hair.
The social media team blessed timelines with photos and video clips from around the Seattle area with the #Mariners77 hashtag.
Pretty groovy, isn't it?
