NEWTOWN SQUARE, Pennsylvania - Englishman Aaron Rai emerged from obscurity to win the PGA Championship on Sunday, firing a sizzling 65 at Aronimink Golf Club to capture the Wanamaker Trophy.

The 31-year-old started the tournament as a 300-1 outsider but kept his composure throughout the final round. He picked up four birdies on the back nine, including a monster 68-foot putt at the 17th, to become the first Englishman in 107 years to win the PGA Championship.

Rai, known as one of the kindest and most respectful players on tour, credited his humble upbringing in the English Midlands as the son of immigrants from India and Kenya. His father quit his job to focus on Rai's golf from age four, instilling a habit of wearing two gloves and putting head covers on irons as a reminder of how precious the clubs were.

Two-time major champion Jon Rahm, who finished tied for second, praised Rai's character. Rai also thanked his wife, Indian professional Gaurika Bishnoi, and his family for keeping him grounded.

'To be the first one in such a long time from England is an amazing thing,' Rai said. 'I'm very proud to be from England, I'm very proud of India and Kenya as well.'
