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. "The MLB 150 patch will be a continuous reminder on the field of the link everyone involved in the game today has with the storied history of professional baseball and MLB."

MLB previously honored the 1869 Red Stockings with commemorative 100th-anniversary patches in 1969 and the 125th anniversary season in 1994.
In addition to the league-wide patches, the Reds will also wear a series of 15 throwback uniforms throughout the season and feature a special commemorative logo on their caps and jerseys. MLB also announced on Tuesday that Manfred will be the grand marshal of the 100th Findlay Market Opening Day Parade in Cincinnati.
