All 30 Major League teams will wear special "MLB 150" patches on their uniforms for the entire 2019 season in honor of the 150th anniversary of the 1869 Cincinnati Red Stockings, the first openly all-salaried professional baseball team.
Every club will also sport MLB 150 patches on its caps on Opening Day, March 28 -- the first time a league-wide anniversary will be commemorated on caps.
The patch, which will be worn on the right sleeves of jerseys, features "MLB" in black and "150" in red surrounding the MLB logo.
"We're excited to recognize the 150th anniversary of professional baseball by honoring our history while celebrating the game and the great players of today," Commissioner Rob Manfred said.
