Japan teen sensation Ryo Ishikawa compared the horror conditions at the Scottish Open on Sunday to the typhoons back home - after he was blown away in his final round. The 18-year-old hit an eight-over 79 on a day of rain and high winds at the scenic par-71 course on Sunday. Ishikawa had started the week with a promising 67 and looked to have a reasonable chance of becoming the youngest winner of this European tour event. But as conditions worsened so did his scores - culminating in Sundays weather that sent him an untimely reminder of back home. 'The rain and wind were almost like the typoons in Japan,' he said. 'So it made it really difficult and it made it hard to play. It was the worst I have played in. I couldn't make any distance with my driver and the cross-wind made it hard as the ball was pushed away. 'It was conditions I wasn't used to playing in.' Ishikawa began his day at three-over and was keen to put in a good score to boost his confidence ahead of next week's Open Championship at St Andrews. He started with two bogey fives, but redeemed himself immediately with an excellent eagle three at the par-five third. But that was the only highlight of his day and further bogeys at the fourth, eighth and ninth saw him reach the turn in 39. The youngster famously posted a 58 back in May and while that round was sprinkled with birdies, bogeys were the order of day at Loch Lomond. He dropped a further five shots in the closing nine holes to end the tournament on 11-over par and well down the leader board. It was a disappointing end to the week - although the scoreboard was littered with scores in the high-70s and 80s - and he now turns his attention to St Andrews when he makes his second appearance in the Open. Last summer at Turnberry, he partnered Tiger Woods and again failed to cope with the Scottish wind and, along with the World Number One, bowed out at the halfway stage. But he has shown this year that he can compete on the biggest stage and will go into next week's event fresh from an excellent showing at last month's US Open. He wowed the crowds at Pebble Beach and was tied for second after the second round before finishing joint 33rd. He will look to build on that showing at St Andrews and is confident his experience at Loch Lomond will help him cope with anything next week throws at him. He added: 'This event will prepare for me next week. I won't be surprised by any weather conditions now after that. 'I am looking forward to it now. I missed the cut last year and my first aim is to play the final two rounds. I have played St Andrews once before and the fairways were very wide. It was interesting experience and I'm looking forward to going back.'
