Unflappable American Brian Harman romped to a six-stroke victory at the 2023 Open Championship as he held a high-calibre chasing pack at bay on the greatest day of his career at the rain-drenched Royal Liverpool on Sunday.

The 36-year-old PGA Tour stalwart, an avid hunter back home in Georgia, offered hope for those wanting a thrilling conclusion to the 151st championship, with a few early errors.

But the left-hander proved elusive prey for his bedraggled pursuers as he closed in on his first major, turning the final day into a procession as he plotted his way around the bunker-laden layout with a one-under 70 for a 13-under total of 271.

Rarely has an Open been concluded in such appalling weather conditions, but the diminutive Harman did not care one iota as he spurned the offer of an umbrella to be presented with the Claret Jug, rain streaming off his shaven head.

“I’m looking at the forecast and then get out there and it’s like Armageddon, it was really tough,” Harman, who will celebrate back home by taking his new tractor for a ride, told reporters.

“I haven’t historically done very good in the rain. It’s just always bugged me, but I was really proud of the way that I struck the ball today.

“Hats off to the fans. Damn sure I wouldn’t have been out watching golf today.”

Few of the thousands huddled under a sea of umbrellas would have tipped world number 26 Harman to win before the tournament.

But he proved that the old adage “drives are for show and putts are for dough” still applies as his magic touch on the greens kept him out of reach.

Spain’s Jon Rahm, Austria’s Sepp Straka, South Korea’s Tom Kim and Australian Jason Day were tied for a distant second place with pre-tournament favourite Rory McIlroy and Emiliano Grillo a further shot back.

In control

Harman had seized control of the tournament with a sensational second-round 65 on Friday and never loosened his grip.

He began Sunday’s climax five shots clear of compatriot Cameron Young and six ahead of Rahm, who had roared into contention with a course record 63 on Saturday.

It needed someone to shoot very low or a Harman collapse to make things interesting, and when the American bogeyed the second hole and the fifth, after driving his ball into a gorse bush, Masters champion Rahm briefly closed to within three strokes.

Harman’s previous best performance at a major was in the 2017 US Open when he led by one stroke after 54 holes only to be overhauled by fellow American Brooks Koepka.

But this time, with the largest three-round Open lead since McIlroy won on the same course in 2014, he responded to every setback in style with his trusty putter again proving to be his weapon of choice.

Birdies at the sixth and seventh eased any nerves, and Harman reached the turn with his five-shot lead intact as Straka and Kim emerged as his unlikely challengers.

Incessant rain dampened the spirits of those trying to reel him in, although four-time major winner McIlroy had threatened to spice things up with three birdies in his first five holes.

Once again, however, the Northern Irishman could not sustain his charge as his near 10-year wait for a fifth major goes on.

Likewise, Young, Rahm, Day and England’s Tommy Fleetwood were all unable to hole the putts that would have at least asked some questions of Harman’s nerve.

Soggy end

McIlroy’s fire was doused in the deluge, although his 68 was his best round of the week. Local favourite Fleetwood looked like a drowned rat as his challenge came to a soggy end with a triple-bogey after finding the dunes at the back of the 17th.

Harman’s third bogey of the day, at the 13th, opened the door ever so slightly and Straka momentarily got within three strokes when he holed his fifth birdie of the day at 16.

But rock-steady Harman responded by sinking a curling birdie putt at the 14th and when he rolled in another at the 15th the Claret Jug was as good as in the bag.

The treacherous par-three 17th and long 18th could have been nerve-racking for a player who had not tasted a victory of any sort since 2017. But not even a Merseyside monsoon could rain on Harman’s parade as he enjoyed a victory march down the last.

He was denied a fourth successive round in the 60s, but after rolling in his par putt his poker face finally cracked into a smile as he bumped fists and embraced his caddy Scott Tway.
