AN astonishing miscalculation by Anders Forsbrand cost Sweden a lucrative place in the final of the GBP1 million Alfred Dunhill Cup yesterday morning. Leading Fred Couples by one shot with two holes remaining in the decisive anchor match against America, the Swede found a watery grave at the 17th when he pulled his approach 40 yards left of the green . . . and into the Swilcan Burn. The result was a double-bogey six which enabled Couples, who had trailed since the 13th hole, to eke out a tense two-stroke victory, 67-69 in the medal matchplay format. Although Jesper Parnevik produced the best round of the week, a six-under-par 66, to beat Payne Stewart by two, John Daly's three-shot triumph, 68-71, over Joakim Haeggman saw the Americans through. Instead of vying for the GBP300,000 first prize, the sunken Swedes had to content themselves with GBP91,000 between them. In the final, the US took on England who had emphatically seen off the challenge of Ireland in the opening semi-final. For the second day in succession the start of play was delayed as overnight frost took its toll on the course. But when the semi-finals did get under way at 10 am, the English trio of Mark James, Peter Baker and Nick Faldo were soon into their stride, taking advantage of the relatively mild temperatures and lack of wind. Mancunian James, putting behind him his undistinguished 79 on Saturday when he lost to South Africa's Fulton Allem by eight strokes, made four birdies on the front nine to build up a commanding lead which Ronan Rafferty was unable to bridge. ''It must have been 15 degrees warmer out there than earlier in the week and it's the best I've played for a month or so,'' said James, whose 67 was three shots better than Rafferty. With James safely back in the clubhouse, attention turned to Baker, whose narrow triumph over Ernie Els had enabled England to scrape through to yesterday's knockout stages. Three shots ahead of David Feherty with four holes to play, Baker appeared to be in control. But he pulled his drive into sand at the 15th to drop a stroke and over-struck his approach at the 17th which ran across the road. While Baker took five, Feherty made a miraculous up-and-down from the notorious Road Hole bunker to reduce the deficit to one. But the genial Northern Irishman was unable to conjure a birdie at the last and Baker clung on. Said Baker: ''It was nice to getthe winning point again.'' Faldo, although not at his best, was never seriously threatened by Paul McGingley. His two-under-par 70 was four better than the 1991 Walker Cup representative.
