LYTHAM ST. ANNES, England — Ernie Els felt something special could happen at the British Open, and it did.All because of a collapse by Adam Scott that no one imagined. Four shots ahead with four holes to play — after eight straight holes with nothing worse than par — Scott bogeyed them all and had to fight back tears on the 18th green Sunday as the magnitude of his meltdown began to sink in. Els, who started the final round six shots behind, finished off a flawless back nine with a 15-foot birdie putt for a 2-under 68 that looked as if it would do little more than lock up another runner-up finish at Royal Lytham & St. Annes.
