British number three Jamie Baker says Wednesday's meeting with Jo-Wilfried Tsonga at the Aegon Championships will be the biggest match of his career.
Baker and second seed Tsonga are third on Centre Court at Queen's Club after the 25-year-old Scot beat Oliver Golding in the first round.
"This is definitely my biggest match," said Baker. "I've never played somebody ranked as high in a competitive match."
"This is what I train for - to play against people like him."
With world number 203 Baker was the only Briton to join defending champion Andy Murray in the second round.
It was just his second ATP World Tour level win since turning professional in 2004 and earned him an encounter with one of the sport's leading players.
Tsonga, ranked fifth in the world, reached the Australian Open final in 2008 and has made the quarter-finals or better at three of the last four Grand Slam tournaments.
The Frenchman is back in action for the first time when he had four match points.
"I think I've just got to enjoy the match," said Baker, who won a Futures event in Mexico in April and is set to enter the world's top 200 for the first time after Queen's.
"I was watching Tsonga play Djokovic and I said to the person I was with, 'I wonder what I'd actually do if I played one of these guys'. I guess I'm going to have to think about that tonight.
"He's an unbelievable athlete. I played him in a Challenger [in Lanzarote in 2007] and the next January he got to the Australian Open final."
Baker is preceded on Centre Court by fellow Scot Murray, who begins his grass-court campaign against world number 65 Nicolas Mahut.
The Frenchman beat Rafael Nadal en route to the final of Queen's in 2007 and is undaunted by the prospect of facing home favourite Murray, the top seed and two-time champion.
When asked if he believed he could cause an upset, Mahut replied: "Yes, of course. Otherwise I wouldn't come on the court.
"I beat Rafa here, I was one point away from beating [Andy] Roddick when he was the top five. I know I can do well. I know I can beat top players on this surface. I believe in myself.
"But I know it's a challenge to play against a top-four player. He's the favourite. I just have to enjoy the crowd, enjoy the Centre Court and play my game.
"If he plays well then it will be very difficult for me. But it will be his first match on grass and that's not easy, so you never know."
