Ernie Els opts out of European Open

Ernie Els has changed his mind about playing the European Open at The London Club in Kent the week after next.
At the start of the month it was announced that the former Open and US Open champion would be competing in the event for the first time in 15 years, but a spokesman for Els' management company confirmed today that he had pulled out.
"It is nothing sinister and purely a scheduling thing," said Martin Hardy. "Ernie occasionally gets a few twinges in his knee and looked at his preparations for the US Open."
The 39-year-old South African will play in next week's BMW PGA Championship at Wentworth - the course he has re-designed and where he has won a record seven World Match Plays - before returning to the United States for The Memorial in Ohio on June 4-7.
That comes two weeks before the second major of the year at Bethpage Black on New York's Long Island.
Els had surgery on his knee after a boating accident in 2005.
