There was a baseball team back in 1849, out of New York City called, the Knickerbockers. During the games, they would wear straw caps on their heads to give them cover from the sun. The headwear progressed and players then started to experiment with various versions of that, eventually leading to a uniform cap that showed up on the Detroit Tigers, in the early 1900s, sporting the team’s logo. According to Epic Sports, the stitched bill we’re used to seeing started around 1903, with the sporting goods company, Spaulding.
