Graeme McDowell: Paul Dunne has that Spieth maturity to him

Graeme McDowell thinks Paul Dunne seems like a wise-old owl.

Irish amateur Paul Dunne will turn professional later this year after taking the 144th Open Championship by storm and major winner Graeme McDowell believes the 22-year-old has the talent to succeed immediately.

Dunne began the final round at St Andrews in a share of the lead looking to become the first golfer from the unpaid ranks to win the Claret Jug since Bobby Jones in 1930.
