Northern Ireland teenager Rory McIlroy will take a four-stroke lead into the final round of the European Masters after a blistering third round of 66 on Saturday. Victory on Sunday would make the 19-year-old, who has led this Alpine event from the start, the third youngest winner in European Tour history. South African Dale Hayes was only 18 when he won the 1971 Spanish Open, while Seve Ballesteros was just five days younger than McIlroy at the 1976 Dutch Open. The Northern Irishman, who carded a 63 in Thursday's first round, stands at 13 under par for the tournament. His closest challengers, all on nine under, are England's Robert Dinwiddie, French pair Christian Cevaer and Jean-Francois Lucquin, Spaniard Alejandro Canizares, Argentina's Juan Abbate and also Julien Clement, a Swiss player ranked 779th in the world. Australia's defending champion Brett Rumford, joint top at halfway with McIlroy, threw down the gauntlet with an opening 40-foot eagle putt. But McIlroy had already hit his approach to the par five to three feet, made the putt for a matching three and by adding six birdies went on to score a 66 to the Australian's 73. Reid leads Sorenstam In Denmark, English rookie Melissa Reid eagled the last two holes for a 7-under 66 and took a six-shot lead over Annika Sorenstam going into the last round of the Nykredit Masters. Reid, who finished runner-up twice on the Ladies European Tour this year, has a 36-hole total of 133. That's 13-under par on Simon's Golf Club course. Sorenstam, making her last appearance in Europe as a pro golfer, shot a 68 Saturday and shared second with Martina Eberl of Germany (73). Sorenstam, who started on the back nine, eagled the long 12th - her third hole. She also had three birdies. The 37-year-old Hall of Famer from Sweden, winner of 10 majors and 72 LPGA titles, will retire at the end of the season to start a family and pursue business interests. Villegas moves ahead Colombia's Camilo Villegas fired a five-under-par 65 to seize a one-shot lead after the first round of the weather-hit BMW Championship on Friday. Villegas, chasing his first PGA Tour title, was hotly pursued by Americans Kenny Perry, Steve Stricker and Tim Herron, Australian Stuart Appleby and Argentine Andres Romero, who all shot rounds of 66. The third and penultimate event of the PGA Tour playoff series, the BMW got off to stuttering start with first-round play pushed back a day after the remnants of Hurricane Gustav swept across the Bellerive Golf Club on Thursday. The players face a grueling Saturday with 36 holes scheduled to get the $7 million event back on course for a Sunday finish. Fiji's Vijay Singh opened with a level-par 70 to stand five shots off the pace. Sergio Garcia and Mike Weirare in contention with the Spaniard shooting two-under 68 and the Canadian 69. South African Ernie Els and world number two American Phil Mickelson also opened with 68s while British Open and PGA championship winner Padraig Harrington was among a group of 15 players one shot further adrift.
