German Martin Kaymer won the International in Munich - but only after losing a six-shot lead and being forced into a play-off by Dane Anders Hansen.

After three days of superb golf Kaymer struggled to the turn in 38 and ran up a triple-bogey eight on the long 11th, putting two balls in the lake short of the green.

But the 23-year-old, now sixth in the Ryder Cup race, birdied two holes later and then, needing another on the par-five last to match Hansen's 15-under-par total, was on in two and almost made a 40-foot putt for eagle and the title.

Back they went to the same hole and while Hansen was in two bunkers Kaymer hit a massive drive and an even better approach to seven feet. When the twice European PGA champion three-putted for a bogey six, Kaymer had three for it, but two-putted for birdie.

Paul Casey, John Bickerton and Mark Foster tied for third on 13 under.

Hansen, who had knee surgery under a month ago and was originally told he could be out for four to six weeks, had been eight behind at the start of the day, but closed with two 67s.

Gary Murphy (seven-under) finished as the leading Irish player with Peter Lawrie another five back.
