South Korean golfer Byeong-Hun An had a round to forget on the opening day of The Players Championship at Sawgrass, carding a remarkable octuple-bogey at the famous 17th hole on Friday (NZ time).
Lining up at the tee already at +1 for his first round, An's first effort flew 124 yards - hitting the edge of the green and landing in the water.
To make matters worse, An's next effort didn't fare any better, finding the water again.
With the best he could hope for on the par three now a bogey, An's third attempt left him fishing his ball out of the water for a third time, before a remarkable fourth straight effort also ended up in the drink.
An's fifth attempt, now up to his ninth shot thanks to four penalty strokes, finally managed to find the green, but two missed putts meant he'd have to settle for an eleven - eight shots over par for the hole.
To his credit, An took to Twitter after his round, poking fun at his poor day at the office.
"We all have bad days in our life and we just have to learn to move on.....," An wrote.
"But it was a horrendous f****** tee shot on 17th."
An finished his opening round at +11, in a four way tie for 150th place alongside American duo Kyle Stanley and Jimmy Walker. Meanwhile, Sweden’s Henrik Stenson fared even worse, finishing at +13 over for his day’s work.
Staggeringly, An' woes aren't the worst in the course's history, after American Bob Tway shot a nonuple-bogey (nine shots over par) on the same hole back in 2005.
