Wawrinka, Tsonga engage in mid-match spat in Melbourne
The Swiss player had aimed a ball at his French opponent, who did not take kindly to it. "Are you looking for trouble?" asked Wawrinka.
Update:
Stan Wawrinka and Jo-Wilfried Tsonga were involved in a heated exchange during their Australian Open quarter-final on Tuesday.
The Swiss player appeared to aim a volley directly at Tsonga during a rally and the Frenchman reacted with an icy glare at the changeover.
Wawrinka responded by accusing Tsonga of giving him the evil eye, leading to a war of words between the players during the break between games.
