It remains to be seen if MLB leaves Japan with a victory on the field, but the league feels like it's hit a home run on the business side of things.

MLB and Under Armour announced a new partnership between the two sports entities on Friday morning at Under Armour's Harajuku location. Under the deal, the sports apparel company will be licensed to produce various MLB products including T-Shirts, polo shirts, sweats and more.

The timing of the announcement was no coincidence.
