England's Oliver Smith carded quite possibly the wildest round of golf of all time during the first round of the Galvin Green PGA Assistants' Championship at Coxmoor Golf Club in Nottinghamshire.
Smith got off to a shocker of a start with a nine at the opening par-4, and he then exchanged a bogey at the second with a birdie at the third.
But to his credit he rattled off four birdies in a row to go out in a very respectable 1-over 36, and then instantly moved into the red when making a hole-in-one at the par-3 10th.

But that was where it all went wrong for Smith, who after making par at 11, then bogeyed the 12th and made a disastrous 11 at the par-5 13th.
Three pars followed thereafter, before he finished off with two bogeys to sign for a back-nine 43 and 8-over 79.
Here's a look at his dramatic scorecard...
"This would've led to a difficult post round conversation with the coach I imagine," tweeted European Tour pro Eddie Pepperell.
Smith's playing partner, Mathew Webb of Bedlingtonshire Golf Club, tweeted that Smith maintained his sense of humour despite the chaos of his scorecard.
"He's a good lad banter all the way. When he made the 1 he went wild then after the 11 I said 'I haven't seen 3 1's on a card before'."
