Todd Hamilton beats Ernie Els, winning the 133rd Open Championship

Little-known American Todd Hamilton beat Ernie Els in a play-off to clinch the Open title at Royal Troon.

The pair tied at 10 under when Hamilton bogeyed the last but he bounced back to win the four-hole play-off by a shot.

Masters champion Phil Mickelson was third on nine under, with England's Lee Westwood fourth on his own at six under after a closing 67.

Tiger Woods finished at three under and local hero Colin Montgomerie ended up a disappointing two over after a 76.

The 38-year-old Hamilton won his first major title after Els pulled his tee shot en route to a bogey at the short 17th, the third extra hole.

The pair shared pars at the first and second holes and Els was unable to force a tying birdie on the 18th.
