Reaction from Phil Mickelson after he became the oldest player to capture a major title in the history of men's golf on Sunday by winning the PGA Championship at Kiawah Island in South Carolina at the age of 50. On a dramatic final day at Kiawah Island, Mickelson held his nerve as his challengers dropped away and after a one over par final round 73, Mickelson finished on 6-under for the championship, two shots clear of fellow American Brooks Koepka and South Africa's Louis Oosthuizen. Four players tied for third on two under par, including European Ryder Cup captain Padraig Harrington, who is only 14 months younger than Mickelson. It was a 6th major crown for 'Lefty' and his second PGA Championship title - Mickelson's first came back in 2005.
