Apparently whilst everyone was getting carried away with Rory McIlroy's blistering course record at Quail Hollow last week, Ishikawa shot a 58 (12 under on the day)


Teenager Ryo Ishikawa carded a 12-under-par 58 - the lowest score ever on a major tour - to win the Crowns tournament in Nagoya.

The 18-year-old began the last day six shots behind leader Shigeki Maruyama but made 12 birdies to record a five-stroke victory at 13 under par.

"It's absolutely unbelievable, I don't know where all those birdies came from," said Ishikawa.

"Seeing my score improve by 12 strokes at the end... it's like a dream."

The previous Japanese Tour record of 59 was set by Masahiro Kuramoto in the first round of the Acom International in 2003.

There have been three 59s on the US Tour, set by Al Geiberger, Chip Beck and David Duval - who recorded the feat in 1999.

In Europe, the current record is 60 which has been equalled 14 times.

American Jason Bohn had a 58 on the Canadian Tour while Shigeki Maruyama recorded one in US Open qualifying.

Annika Sorenstam also had a 59 on the LPGA Tour.

In Nagoya, Japan's Hiroyuki Fujita and Australia's Paul Sheehan finished tied in second place on eight under.

Ishikawa, who missed the cut at the Masters in Augusta after finishing four over par, captured the Japanese golf Tour's order of merit in 2009.

"The record hasn't sunk in at all at this point. It will take a bit of time. Winning such a big tournament so soon in my career is also amazing," said Ishikawa, whose victory at the Crowns tournament represented his seventh career title.
