Argentina, South Africa and Sweden hold a three way share of the lead at the end of day one of the World Golf Championship World Cup currently being played in Barbados, with the Australian team of John Senden and Mark Hensby four shots behind and tied for 13th. South Africa&aposs team of Rory Sabbatini and Richard Sterne finished their round of seven-under 64 by making birdie at the par-three finishing hole, as did the Swedish team of Henrik Stenson and Carl Pettersson with Angel Cabrera and Andres Romero recovering from a bogey on the first to fire five straight birdies on the back nine and join the leaders after a day of golf played in grueling conditions. On a blustery and often rainy day in Barbados winds accelerated up to 75kmph and players were tested in the conditions, much the same as the last World Cup. Senden and Hensby had a fairly steady round including four birdies and one bogey and are four shots behind the leaders with a group of three. Senden, the recent MFS Australian Open winner and Hensby, a member of this years Presidents Cup team are paired at the World Cup for the first time. Stephen Dodd and Bradley Dredge paired together for victory last year for Wales and are close to the top of the leaderboard again. They teamed for a six-under-par 65 and share fourth with Bernhard Langer and Marcel Siem of Germany. The American duo of Stewart Cink and J.J. Henry re-kindled some of their Ryder Cup magic on Thursday. They combined for a five-under-par 66 and are part of a group including Luke Donald and David Howell of England and the Korean pair of S.K. Ho and Charlie Wi all tied for sixth place. Overall 15 teams, or nearly two-thirds of the field, finished within four shots of the lead in Thursday&aposs fourball format. Friday&aposs second round will feature the 24 nations in foursomes, or alternate shot action, before the format switches back to fourballs on Saturday. The competition will end with foursomes on Sunday.
