Under Armour does not take over the MLB contract until 2020. I would expect Majestic to roll with this design until their contract expires. Under Armour will, almost certainly I would venture, run a new design for the 2020 season - shirts, jackets, and undershirts. My guess would be the UA will be more in tune with what actual umpires want and understand that what the MLB guys wear will trickle down and have its own, although rather small, market share among amateurs. Time will tell, I guess.
