Fifteen-arrow record holder Schloesser, nicknamed "Mister Perfect", had won both of the previous encounters between the two, but opened with three eights in his first five arrows.

Elmaağaçlı, shooting flawlessly, hit five consecutive 10s to take a six-point lead.

Then, however, as the wind picked up ahead of his last shot in the first end, the Turk fumbled with his arrow and, as the clock ticked down, ultimately failed to get it on to the rest in time.

The horn sounded and his shot registered as a miss, to gasps from the crowd.

Schloesser was duly galvanised and hit three 10s to edge further ahead, eventually winning 139-135 in one of the lowest-scoring men's finals ever seen on the World Cup circuit.

“I ran out of arrows,” Elmaağaçlı said. 

“I had to use an arrow I knew was ‘bad’, and it fell off the rest and I wasn’t able to shoot it."

Schloesser, in turn, has been handicapped by using a new back tension release system rather than his normal trigger one.

There were less surprises in the corresponding women's final as Colombia's world number one Sara Lopez secured a third successive World Cup victory following wins in Medellin and Mexico City.

She won 147-145 over Danish opponent Sarah Sonnichsen.

Sonnichsen had already enjoyed golden success by this point, however, forming part of the Danish team which won a shoot-off 29-28 over Russia after a 227-227 draw.

Iran enjoyed a narrow 229-228 victory over United States in the men's final.

Finals using the Olympic recurve bow are due to take place tomorrow.
