Raul Ballesteros, the 25-year-old nephew of Seve, had his lowest round on the European Tour today - and came off bitterly disappointed.
After 16 holes of the Spanish Open at San Roque, Ballesteros - who has yet to earn a tour card and is playing on a sponsor's invitation - was an unbelievable nine under par and four clear of the field.
But he finished bogey-double bogey for a 66 - still his best by two - and lost the lead to Portugal's Jose-Filipe Lima and England's Graeme Storm.
Colin Montgomerie, meanwhile, stood six-under before bouncing into a bush off a cart path and double-bogeying the fifth, his 14th, for a 68.
"I've had a couple of 61s at my home course Pedrena, but I've never been nine-under on tour before and I got a bit nervous," commented Ballesteros.
"But that's golf. These things happen. Before the 17th I was thinking nothing could go wrong."
Ballesteros, with a best finish of only 33rd in 32 previous tour appearances, turned in 32 and then started the front nine with five more birdies in seven holes.
He missed the green at the difficult short eighth, however, and on the next chipped from one side of the green into the lake on the other.
Irish pair Stephen Browne and Peter Lawrie are both very much in touch with the leaders as they finished their rounds two shots off the lead on five-under-par.
