Sweden's Robert Karlsson and Henrik Stenson won the 54th World Cup of Golf by three shots on Sunday after a masterful nine-under-par 63 in the final round foursomes. European number one Karlsson and world number 12 Stenson, the highest-ranked players at the $5.5 million tournament, overhauled joint overnight leader Spain with nine birdies in a blemish-free round to finish at 27-under and share $1.7 million. “It's fantastic to win for Sweden ... it's been a while,” said Karlsson after matching Per-Ulrik Johansson and Anders Forsbrand's feat in Rome in 1991. Spaniards Miguel Angel Jimenez and Pablo Larrazabal, who shot a stunning 63 of their own in Friday's foursomes, were second after a final round 70. Australians Richard Green and Brendan Jones, who shared the lead with Spain after the third round, carded a disappointing 76 to drop to a share of third alongside Japan's Ryuji Imada and Toru Taniguchi on 18-under. Defending champion Scotland finished tied for 19th with its par 72 on Sunday concluding a poor weekend for Colin Montgomerie and Alastair Forsyth.
