This was a dangerous one - not only had Dellacqua just reached the biggest semifinal of her career at the grass court lead-up tournament in Birmingham, but Radwanska came in with a 24-19 career record against left-handers, hardly the domination one would expect from a World No.4, and former No.2.
The Turning Point
There were a few turning points early on - Radwanska went up early in the first set, but Dellacqua clawed her way back into it, and she was back on serve at 4-5, hoping to push the set into overtime.
Radwanska turned the heat on from there, breaking to take the set and absolutely racing through the second set at love - dropping just eight points in those six games - to close the match out, 6-4, 6-0.
By The Numbers
For the match, Radwanska's stat sheet was impressive - she put together a +11 differential of winners to unforced errors (19 winners to 8 unforced errors). But once that first set was tucked away that stat sheet went to another level - she ripped seven winners to just one, yes one, unforced error.
Radwanska's win over Dellacqua was her 30th career match win at Wimbledon, by far the most she has at any one Grand Slam (she has 24 at the Australian Open, 18 at the French Open and 16 at the US Open). This is also the only one of the Grand Slams she has been to the final of, in 2012.
"It's always great to be out on Centre Court, especially here, where I have my best Grand Slam memories," Radwanska said. "Wimbledon is the only Grand Slam where I did the final, so of course I have the best memories here on Centre Court. I was really looking forward to playing there again.
"I think the surface has a lot to do with it. Grass is a surface I've really liked since the beginning. I've been playing here since 2005. Unfortunately the season on grass isn't that long.
"But that's why I really wanted to do well here."
And like always, Radwanska was given a warm reception from the Centre Court crowd.
"It means a lot that the people like my tennis and like watching my game," she added. "When people say I make tennis entertaining and they love watching me, it's the best thing I could hear."
