Paul Dunne earned Under Armour a crazy amount of money on Sunday

Sign this lad up.

Under Armour made a shrewd move, in 2013, when they signed up Jordan Spieth to a 10-year clothing and sponsorship deal. The Texan now has two Major wins and is one shot off the lead at The Open Championship. Spieth just happens to be behind 22-year-old Irishman Paul Dunne. Playing collegiate golf out of the University of Alabama, the Wicklow native shares The Open lead, at -12, going into today's final round. Dunne has already been mistaken for Spieth by fans at St Andrews and that could well be down to the fact that he is kitted out in similar Under Armour gear. While Dunne does not have any deals signed with the Baltimore-based sports clothing company, he was supplied with some nifty polo tops, pullovers and windbreakers. His surge to the top of The Open's leaderboard earned Under Armour an awful lot of free advertising on Sunday. https://twitter.com/darrenrovell/status/622828922158321664 In fact, and this just crossed our mind, Under Armour are getting more gratis advertising from us for merely writing this article. Crafty. The TV coup has been lauded in The Baltimore Sun, who have a unique way of describing Dunne's appearance.

Jeff Barker writes: 'Dunne, who has a slight build and bears a resemblance to actor Topher Grace, is the surprise of the tournament. Through 54 holes, his 12-under par ties him for the lead with Jason Day and Louis Oosthuizen.'

Ladies and gentlemen, Paul Dunne.
