Lee Westwood won the Ballantine's Championship on Sunday with a flawless final round of golf to retain his position as world number one. The Englishman proved his class at the Blackstone Golf Club near Seoul, carding five birdies on his way to a superb last round 67 and 12 under par for the tournament, a shot clear of Spain's Miguel Angel Jimenez.
Westwood did not drop a single shot on his last round but faced an agonising wait in the clubhouse as Jimenez came up the easy par five 18th breathing down his neck.
But the Spaniard's hopes of forcing a playoff were dashed when he overhit his second shot into a bunker behind the green and missed the birdie putt he needed from 15 feet. Westwood needed a top five finish at the Ballantine's to stop Germany's Martin Kaymer overtaking him as number one after just a week on top and the win is his on the European Tour since November 2009. He has now recorded back-to-back tournament victories following his triumph at the Indonesian Masters last week.
