The Triple-A Fresno Grizzlies are an affiliate of the Houston Astros, and on Saturday they will tap into one of the most glorious uniforms in baseball history for a special throwback night.

Holy ! Our @Astros retro-inspired theme jerseys have arrived. We wear them Saturday night at Chukchansi Park. #MiLB pic.twitter.com/BQg70hxAYo — Fresno Grizzlies (@FresnoGrizzlies) July 16, 2015

Fresno will wear those 1970s-1980s-inspired uniforms against El Paso, which is the Padres' Triple-A affiliate. Just think, if the Chihuahuas bust out the old brown and mustard Padres uniforms, Saturday could be the greatest throwback jersey night in history.

To top that, the Grizzlies will auction off these game-worn beauties for charity after Saturday's game.
