Shane Lowry clinched victory at the BMW PGA Championship on the final hole at Wentworth, pipping Jon Rahm despite a historic final round from the Spaniard.
Following the suspension of play on Friday due to the passing of Queen Elizabeth II, the tournament was reduced to 54 holes.
Rahm's round of 62 on Sunday gave him the clubhouse lead on 16 under par, and it could have been even lower had he not narrowly missed some birdie attempts early on.
His total of 29 on the back nine, which included two eagles, was the lowest in the tournament's history, despite a bogey on 15.
It looked likely that Lowry would overtake him when the Irishman also reached 16 under with six holes remaining, hitting an eagle on the fourth, and birdies on the seventh, eighth, 10th and 12th.
However, Lowry – the 2019 champion at The Open Championship – went on to par the next five, leaving a nervous wait to see if he could take advantage on the par five 18th.
Lowry did just that after an excellent approach shot that left him with two putts for birdie, which he executed to seal a sixth DP Tour win of his career.
Rory McIlroy finished joint-second with Rahm after carding a final round of 67, while overnight leaders Viktor Hovland and Soren Kjeldsen both slipped to T5 after only being able to go round in 70.
Patrick Reed had set the bar early in the day with his impressive round of 63, before Rahm overtook him, and the American also finished joint-fifth alongside Thomas Detry on 14 under, with Talor Gooch able to earn outright fourth after an eagle at the 18th.
A round of 65 from Lee Westwood saw him climb to T13, where he was joined by world number 443 Matthew Southgate, who carded his second round of 67 in a row.
