The curious case of John Millman, whose game gets better as his battered body gets older, is a real-life tennis fairytale.

At 26 and two years after he thought the opportunity had seemingly passed him by, Millman will make his Wimbledon debut.

The Queenslander had never even set foot inside the All England Club gates before qualifying last Thursday.

“It’s one of those things you dream about and I’m just glad I could make it a reality. It’s an amazing feeling,” Millman said ahead of his first-round clash with Spanish 19th seed Tommy Robredo on Monday.

“To be honest, I got a bit lost trying to get here. I’ve still got to find my bearings.”

Until now, the journeyman’s biggest thrill in an injury-riddled career featuring just two previous grand slam main-draw appearances – both ending in first-round losses at the Australian Open – was taking a set off Roger Federer in front of his home supporters in Brisbane in January.

Millman will share this magical experience with his mother Shona and father “Big Ron” after shouting his folks a trip to SW19.

He said “mum was getting a little bit tipsy with my sister” while at home monitoring his final-round qualifying encounter through live scoring on the internet.

But she still managed to book her flight and will be at Court 11 for the last match on day one the championships (starting about 3am Tuesday AEST).

“I’m getting a bit of a pay day this week so definitely it’s the least that I can do for my parents.

“It’s a pretty special place, not just for me but for them. To watch their son, I think it’s going to be really exciting.”

Millman, who has overcome knee issues, two serious shoulder operations and a year out of the game to make it this far, is guaranteed a cheque for STG29,000 ($A59,000).
