If you watched the Masters on Sunday, you know Jordan Spieth had a very good day. You could argue his main sponsor, Under Armour, had a better one.

They signed Speith to a 10-year deal back in January, Bloomberg notes, guaranteeing Under Armour is the only brand name Spieth will wear on the course.

A key provision?

Under Armour doesn’t make golf clubs, which means Speith didn’t have to change clubs to make the deal — no small thing.

And by the way, I haven’t had a pimento cheese sandwich yet.
