Tiger Woods and Gary Player led the tributes following Phil Mickelson's historic victory at the PGA Championship at Kiawah Island's Ocean Course in South Carolina on Sunday.
Mickelson carded a final-round of 1-over 73 to finish on 6-under and win by two strokes over fellow countryman Brooks Koepka and South Africa's Louis Oosthuizen.
Mickelson, who turns 51 next month, became the oldest player to win a major - erasing American Julius Boros 1968 PGA Championship at the age 48.
Mickelson went on to claim his sixth major championship title and second at the PGA Championship win.
