My mate, who's a top British coach, was at Wimbledon back in 06. The day before the first round, he saw Alex out practising his serve on the Aorangi practice courts. He had eleven old tennis balls - the type you'd use to throw for your dog - in a Tesco bag. He was tuning up for his big match the next day. Against Nadal.
I remember Bogdanovic, only seen him play once, Queens 2010.
