Nike’s logo will be on the upper right chest of Major League Baseball jerseys next season, a far a more prominent position than the Majestic Athletic logo previously on sleeves. A 10-year agreement announced last January replaced a deal announced in December 2016 for Under Armour to take over from Majestic. Majestic had manufactured MLB batting practice jerseys since 1982 and had been the exclusive supplier of game uniforms since 2005.
