Stan lets his racket speak

Former Aussie Open champ Stan Wawrinka engaged in a war of words with Jo-Wilfried Tsonga before winning the only argument that mattered on Tuesday, storming into the semifinals with a 7-6 (2), 6-4, 6-3 win over the Frenchman.

Wawrinka bickered heatedly with the 12th seed during a change of ends after the first set before putting his aggression to better use, wrapping up the one-sided match in two hours and 15 minutes at Rod Laver Arena.

Fourth seed Wawrinka will next battle compatriot Roger Federer who beat German giant-killer Mischa Zverev.
