Australian Open: A bizarre umpiring blunder has marred a third-round Australian Open men's doubles match between Marcel Granollers/Horacio Zeballos and Yannick Hanfmann/Dominik Koepfer.

At set point in the second set tie-breaker, Hanfmann's return to a Granollers serve flicked the let cord. Zeballos, positioned at the net, played a half-volley off the let cord, causing the ball to spin up and over the net.

When the ball cleared the net, it spun back over, and Granollers, in a bizarre move, caught it. Simultaneously, Koepfer's racquet slipped from his grip as he lunged forward in an attempt to play the ball on the opposite side of the net, exercising his right to do so.
