Under Armour will supply uniforms to MLB in 2020

Under Armour won’t begin supplying Major League Baseball uniforms until 2020, returning to the original schedule and abandoning a plan to accelerate the rollout a year earlier, according to officials familiar with the plans.

Major League Baseball and the Baltimore-based sports apparel and footwear brand decided that transitioning from Majestic Athletic to Under Armour as the official uniform provider by next season was not feasible. Under the new timetable, Majestic will continue making the uniforms in 2019.

Major League Baseball is the first of the major professional sports leagues for which Under Armour will provide all the game uniforms. The brand’s logo will appear prominently on one side of the jerseys’ chest area. Majestic’s logo currently appears on the sleeve.

Under Armour and MLB formally announced the 10-year partnership, then scheduled to start in 2020, in December 2016. Under Armour's partner in the deal, sports merchandise retailer Fanatics, was granted licensing rights to manufacture and distribute fan gear. At the time, Kevin Plank, Under Armour’s founder and CEO, called the agreement "a massive statement for our company."

In May 2017, the parties moved the timetable up to 2019, following the announcement that Fanatics had signed an agreement to buy Majestic’s plant in Pennsylvania’s Lehigh Valley and keep production of MLB uniforms and fan wear there. But that timetable proved too ambitious.
