CARLSBAD, CA, USA - The Radwanska sisters both moved through to the quarterfinals for a second week in a row, following up their joint Stanford run at the Southern California Open in Carlsbad.
"I had never played Jelena before and it was a very tough match," Radwanska said. "There were tough conditions today - it was pretty warm out there - so I'm happy that I fought until the very end."
"I was really happy with my game, especially in the second set," Radwanska said. "I started to play much better in the second set, and much more aggressively. I'm really happy to win in two sets."
It goes without saying that the Radwanskas are two of the closest siblings the WTA has ever seen.
"We're really, really close," Agnieszka said. "It's always been like that. Of course we fought a lot when we were kids, but kids always fight, and since then we get along so well. All our life we went to the same schools, practiced together on the same courts, and now we always share a hotel room - I can't imagine playing the same tournament as my sister and not sharing one! That would be so weird."
Don't let the closeness fool you though - the sisters have very different games and personalities.
"She's more quiet on the court, and I'm definitely more emotional," Urszula said. "Sometimes I can scream or throw my racquet. But that's just me - that's my character. I just always want to win!"
"I am more calm on the court," Agnieszka said. "She's more demonstrative on the court, for sure."
So far, big sister has exceeded little sister in career accomplishments - but there was another very famous sister act that began that way, and over time, little sister has surpassed big sister...
"She just needs more time," Agnieszka said. "Right now it's great to see her in great shape, playing well and feeling healthy - she keeps playing better and better, so I'm sure her time will come."
"People expect the same kind of success from me as she has, and they ask me if I'll be as good as she is, but it's just different," Urszula said. "I'm just trying to focus on my game and improving as much as I can, and I think I'm getting there. Maybe I'm just going to it in a different way. It's hard to say.
"But Aga motivates me. I want to be as good as she is. I hope one day I'll be where she is now."
