Wawrinka takes dig at Nadal with 'uncle umpiring' barb

Swiss tennis player Stanislas Wawrinka has reportedly taken a dig at world number one Rafael Nadal following his defeat to the Spaniard at the ATP World Tour Finals, saying that the match umpire had failed to stop Nadal from receiving coaching from his uncle Toni during the game.

Wawrinka, who lost 7-6(5), 7-6(6) in the most enthralling contest of the season-ending tournament so far, can still reach the semi-finals on his first appearance in the elite field if he beats David Ferrer in his final Group A match on Friday and could even set up another showdown with Nadal in the tournament.

According to Sport24, although Wawrinka said that he has nothing personal against Nadal or his uncle, he however, said that everyone is aware that Nadal's uncle is always trying to help his nephew, adding that it went too far during their game.

Wawrinka further said that umpire failed to stop Toni from coaching Nadal before every point, and hinted that the official did not give any second warning to the Spaniard just because he was Nadal.

The report mentioned that Nadal was warned for taking too long between points as he tried to fend off a Wawrinka onslaught at the end of a high-quality opening set.
