Valentin Vacherot beat his own cousin Arthur Rinderknech in the Shanghai Masters final.

Vacherot took a three-set win, 4-6 6-3 6-3.

He succumbed to Rinderknech in the first set but hit back to claim the second and take the match into a decider.

He kept his momentum going into the third set, getting three break points in the first game. Excellent serving from Rinderknech saved the first two break points, but then Vacherot found the angle to win a brilliant rally.

Vacherot held serve to consolidate the break. Rinderknech continued to falter, barking in frustration after a double fault in the next game. But he hauled himself to deuce and took the game.

But Vacherot stayed dangerous and another break saw him control the deciding set. Rinderknech, visibly wilting, could not turn the tide and Vacherot secured a tremendous upset victory.

Both had pulled off stunning upsets to win their respective semi-finals.

Qualifier Vacherot - the world No 204 - beat a limping Novak Djokovic 6-3 6-4, with the Serbian fourth seed taking medical timeouts during both sets.

Vacherot became the lowest-ranked player to reach an ATP Masters 1000 final since the series was introduced in 1990 to set up this contest with his own cousin.

Rinderknech knocked out former US Open champion Daniil Medvedev 4-6 6-2 6-4 in the semi-finals to complete their extraordinary family double.
