After a few rallies with some of the female players last week, he had a practice match with world No60 Carlos Berlocq on Friday which encouraged the Slovak to take a punt and enter.
Yesterday he beat 89th ranked Pere Riba 6-4 6-2 - the Spaniard who was ranked as high as 65 in May last year and was the fifth seed in qualifying. In Riba's defence, he only arrived in the country at lunchtime yesterday but must have been shaking his head when he saw his opponent.
"I think these guys are fine with it - it's tennis. You have to deal with it. They know I am not someone who has just come out of the blue sky. I have something behind me," says Hrbaty, adding that he was nervous yesterday, especially in serving out the match - but managed to send down two aces to win.
"I thought if I have the time and opportunity why not give it a try? To beat a top-100 player is not that bad. I really played well and pushed him all the way."
Today Hrbarty will face Russian born Kiwi Artim Sirtak (434), who beat American Denis Kudla (276) 6-3 6-7 (5) 6-0 .
"I have practised with him a few times," says Hrbarty of Sirtak. "He has a big serve and can hit hard. It will depend how tired I am and how solid he is. Normally if he plays well and I haven't practised that much then I should not stand a chance, unless I play really well like [yesterday]. In my situation it is hard to be consistent."
If Hrbarty beats Sitak, he will likely face Frenchman Adam Mannarino (ranked 87 in the world), the third highest player still standing. If he then qualifies for the big show, he will need to juggle commentary with court time and he is promising some special features out there.
"If I qualify maybe you will have the experience of something that has never been seen before on the ATP tour."
Hrbarty declined to elaborate but it's understood that Sky is contemplating putting microphones on court - probably beside Hrbarty's courtside seat. That would need to be approved by the ATP. It is believed they have also asked tournament organisers to put a potential Hrbarty match on centre court.
