The marquee group at The PGA Championship this week contains Rory McIlroy & Jordan Spieth, the number 1 & 2 ranked golfers in the world respectively. They'll do battle out on the course with both men looking to one-up the other; however, this isn't the only place that battle will take place. Off the course, Nike (Rory's sponsor) & Under Armour (Spieth's sponsor) will be trying to get the upper hand in the marketing battle that largely centers around both player's clothing.
