Aaron Baddeley gives hope to Open contenders with closing 64

Australia's Aaron Baddeley gave hope to Jordan Spieth's rivals as the final round of the 146th Open Championship got under way at Royal Birkdale.

Spieth held a three-shot lead over fellow American Matt Kuchar and was an odds-on favourite to join Jack Nicklaus as the only players to win three of golf's major titles before the age of 24.
