Timothy Mack (right) and Toby Stevenson celebrate their medals

Stevenson, jumping in his distinctive protective headgear, failed with three attempts at 5.95 after Mack had cleared with his second of three attempts.

Italian Giuseppe Gibilisco took the bronze with a season's best 5.85.

Mack first attracted international attention when he won the 2001 Goodwill Games in Brisbane.

"It's pretty unbelievable," he said. "I can't put it into words, it kind of seems like a storybook."

Mack said 2001 had represented a turning point in his career.

"We were trying to figure out what it was that kept me from jumping higher than anybody else.

"Basically it took three years for all that to come together."
