The three-time Major winner, whose victory in this tournament in 2008 at Oakland Hills was the first by a European golfer in the event since Scotland’s Tommy Armour in 1930, is set to tee off at Valhalla in today’s first round (1:35pm Irish time) alongside fellow former champions Phil Mickelson and Tiger Woods.
