Heather Watson faces a daunting challenge when she takes on in-form world number four Agnieszka Radwanska at the Australian Open on Friday.
The British number one, 20, has reached round three in Melbourne for the first time after two dramatic three-set wins.
And she will need to recover quickly to test Radwanska in the opening match at the Hisense Arena at 00:00 GMT.
Radwanska has won all 11 matches she has played in 2013 and picked up titles in Auckland and Sydney along the way.
She also beat Watson in their
only previous meeting at Wimbledon last year
for the loss of just two games.
"That killed me," admitted Watson. "I was so upset. I was playing at home in front of everyone and I just got wiped off the court. Yeah, that wasn't a great experience."
Radwanska, 23, remains wary of an opponent who has risen through the rankings since last summer and is now projected to move to around 40 in the world after the tournament.
"Definitely she's a great young player coming up and I remember that game in Wimbledon," said Radwanska.

"I was really playing well at Wimbledon, I had some great results there. This is a little bit different, a different surface and different story."
Radwanska is smaller than many of the leading players at 5ft 8in and uses court-craft as much as power.
"She's a very different player to most of the girls," said Watson. "She is consistent, has great feel, so it's going to be another physical match.
"I've played her before and I think the first time I played her I just went guns blazing and didn't know what to do. I just went for it way too much.
"This time I am coming in a different player and I am going to approach it differently. I feel more experienced, more confident in my game and this is my second third round [at a Grand Slam] now, so I have been here.
"I'm just looking forward to playing her again."
Asked if she feels she is in the form of her life, Radwanska said: "I hope not, then I can be playing even better.
"I'm definitely happy I can play my best tennis at the beginning of the year, which is always tough after a few weeks just practising.
"I didn't really expect that I could win this many matches in a row. Hopefully I can keep going."
