Wimbledon 2013: Bernard Tomic overcomes absence of his coach and father to progress

Australian sees of Sam Querrey over five sets

Bernard Tomic overcame the absence of his coach and father, as well as an apparent bout of exhaustion, to make it through to Wimbledon's second round.

The 20-year-old Australian saw off Sam Querrey on a sun-drenched Court Three, taking a decider after letting a two-set lead slip.

Midway through the fourth set he called for medical assistance, appearing to be struggling with the heat and the speed of the match - the five sets took just two hours and 10 minutes - before completing a 7-6 (8/6) 7-6 (7/3) 3-6 2-6 6-3 win.

Tomic is also having to contend with having no-one in his corner at the All England Club. His dad, John Tomic, who is also his coach, has been charged in Spain with assaulting his son's former practice partner, Thomas Drouet, but claims he was acting in self-defence.

The ATP have banned John Tomic from attending tournaments in a coaching capacity until the matter is resolved, with Wimbledon officials going one step further and preventing him from attending even as a spectator.

Bernard Tomic certainly looked like he could do with an arm around his shoulder today as he struggled to cope in the fourth, but once that was put to bed he broke Querrey's serve in the eighth game of the decider and then sealed the win.
