A nasty stomach bug has undermined Thanasi Kokkinakis’s Wimbledon debut and the talented teenager says it stinks.

Kokkinakis is recovering and hopes to be back to full health for his first-round clash with Argentina’s 24th seed Leonardo Mayer on Monday after spending two days laid up suffering from Giardia lamblia.

The 19-year-old said he’d been violently ill and couldn’t stop farting for days.

“It’s been pretty messy,” he said.

“It’s been getting better day by day. I threw up 13 times on Monday night. It was pretty incredible. I never had anything like it.

“I spent the last two days in bed, not doing a whole lot.

“I’m back up and at it now. I should be ready to go.”

Kokkinakis has been a breath of fresh of air since bursting onto the scene two years ago when he won the Wimbledon junior doubles title with Nick Kyrgios and then lost the Australian Open and US Open boys’ finals.

But on Friday the youngster, dubbed by Pat Rafter as the “role model” of Australian tennis, politely warned journalists that his flatulence could still strike at any time.

“I passed wind a lot and that’s definitely happening. It was pretty ugly,” Kokkinakis said.

“I felt so bloated. I don’t wish it upon anyone, really.

“But it’s getting better. They gave me some pills and I should be alright.”

The untimely illness forced Kokkinakis to miss his scheduled opening match at The Boodles, a pre-Wimbledon exhibition tournament, but he managed to play two sets against American John Isner on Thursday.

He admitted it was tough to strike a balance between practising and conserving his energy for his Wimbledon opener.

“Because you don’t want to do too much because you want to be fresh,” he said.

“But you want enough to that you’re not slightly underdone.

“I feel like I’ve had good training coming into here, Queen’s as well.

“I’ve just got to trust what I’ve done after French Open.”
