KIAWAH ISLAND, S.C. (Reuters) - Jack Nicklaus and Tiger Woods offered their congratulations to Phil Mickelson on Sunday after the 50-year-old became the sport's oldest major champion by winning the PGA Championship.

Nicklaus holds the record for most men's majors with 18 and Woods is second on the all-time list with 15, and while both have won far more than Mickelson's six his performance clearly impressed them.
