Rose remains four ahead of Harrington

Justin Rose is in sight of becoming the European Tour's youngest number one for 18 years after an amazing rollercoaster ride at Valderrama on Saturday.

Third behind Ernie Els and Padraig Harrington in the Order of Merit race entering the season-ending Volvo Masters, the 27-year-old goes into the final round with a commanding four-stroke lead over Harrington and Yorkshire's Simon Dyson.
