MELBOURNE (Reuters) - A ruffled Rafa Nadal fumed after being called for multiple time violations but composed himself to fend off a gallant Kei Nishikori and reach the quarter-finals of the Australian Open on Monday with a tense 7-6 (7-3) 7-5 7-6 (7-3) win.
Nadal's fidgeting, shorts-tugging preparation before serves is a famous quirk of the Spaniard's game but it fell foul of watchful Greek umpire Evanthia Asderaki, and at exactly the wrong moment.
