The shot was the three-wood Montgomerie played off the final tee of the final game in this year's Ryder Cup at Valderrama.
To beat the Americans, Montgomerie had to halve with Scott Hoch. They were all square with one to play and while Hoch drove into trouble, Europe's No 1 found the middle of the fairway.
From there he was able to hit a nine-iron on to the green and moments later he gave captain Seve Ballesteros the victory he so badly wanted.
"It's the best tee shot I've ever struck in my life," Montgomerie said. "I always use a three-wood at the hole. The idea is to hit it high over the trees and land it soft. I managed that and also got the length I was looking for. The ball travelled 280 yards."Reuse content
