Who wore it first

I think the cardinals have worn a similar uniform in the past

Twins with the heavy red script. White Sox actually had first powder-blue getups in late ‘60s.

Cards had a set from 1976-84, but Tech’s script reminds me more of the Twins.

Royals wore powder blue from 1973-91.

Close to a dozen teams had powder blue at one time between late ‘60s til about 1991.

Expos never had a gray uniform from their debut in 1969 til introducing one in 1992.

Brewers started with powder blue as the Seattle Pilots in 1969 and kept it through 2 or 3 uniform changes until switching to gray in 1985.
