OK, so "old" might be a stretch, but Spieth will be in his 30s when his new Under Armour deal expires. Considering the phenom won a PGA Tour event when he was 19 and just became the legal drinking age this past summer, though, a 31-year-old Spieth is a little hard to imagine.
On Wednesday, Under Armour announced a 10-year contract extension with the young star. Spieth, currently No. 9 in the Official World Golf Ranking after dominating wins at the Australian Open and the Hero World Challenge, first signed with Under Armour in 2013 shortly after turning pro.
The terms of the 10-year deal weren't disclosed, but there is more news from the apparel company. ESPN's Darren Rovell reported Under Armour will release its first golf shoe to the public by spring of this year.
In 2013, Nike signed Rory McIlroy to a 10-year contract. That deal was rumored to be worth $200 million, but it also included McIlroy switching golf equipment.
