While all the other winners breezed through in straight sets, Schiavone and Date-Krumm went to war against each other, putting their incredible variety on display in front of a packed center court crowd. Schiavone came out stronger, going up 4-2 in the first set, but Date-Krumm got back into the match with six straight games, taking that first set, 6-4, and moving ahead by 2-0 lead in the second set.
But from 64 20 down Schiavone reeled off five games of her own and, after getting a critical break in the seventh game of the third set, kept holding serve until she crossed the finish line, 46 64 64.
"Kimiko was playing very well at the start - she deserved to win the first set," Schiavone said. "I played much better in the second set, then the third set was close - I think we had a really good fight."
At the end of the day though, Schiavone maintained her perfect record against the Japanese: 4-0.
"She sees the court like no one else can. She played so well this week. But I don't think she likes playing against me - all of my high shots and my low shots, I don't think she likes facing those."
"To get through to the semifinals here is great," Pavlyuchenkova said afterwards. "I don't think I was playing my best tennis in this match, but it was enough to get through, so I'm happy about that."
"I'm already tired when I think about her!" Pavlyuchenkova said about playing the Italian. "If I try to imagine her game, especially on this court and in these conditions, I know it'll be really tough. I have to prepare myself physically and mentally for a really tough match. I just have to play my game."
"The first couple of games were really long, but then I started to play better and everything was working," Radwanska said. "It was really great to play in front of all the fans here today. Some of the rallies we had were really entertaining and they were cheering a lot, so I hope they enjoyed it!"
Arruabarrena was just too consistent for young South Korean wildcard Jang Su Jeong, 60 64.
"That's the first time I've played her, and she played well all week and the crowd was supporting her a lot, but I just tried my best and I played well," Arruabarrena said. "I was sick earlier this year but I'm feeling really good physically right now, and I'm looking forward to playing against Aga now."
