It appeared the 39-year-old Raymond and 19-year-old Robson would have their hands full with No.4 seeds Ekaterina Makarova and Elena Vesnina. The Russians, who won their biggest WTA title earlier this month at Indian Wells, came into the clash having won 20 of their last 21 matches. However, from 3-3 in the first set, Raymond and Robson won three straight games and from 5-3 down in the second set won four straight games despite having a set point against them at 5-4 for a 63 75 victory.
"With this format, when you get to a super tie-break, anything can happen," Raymond said. "For us, it was great to break back in the second set and serve it out to get it done in two.
"Laura brings so much energy to the court. It's fun to play with somebody who could be my daughter. This is almost a new world to her. She has such a great future ahead of her. Maybe I can teach her a little bit about doubles with my experience. It's fun practicing with her and playing matches."
Raymond certainly does bring experience to the table, as the former doubles No.1 has 79 WTA doubles titles to her name, including three in Miami.
"It's very different playing with a doubles specialist than with another singles player," Robson said. "In the past 12 months, I've teamed up with five or six different people, because I can't get into anything other than the Slams.
"It has been exciting. I thought we played awesome today. Lisa hasn't missed a volley all week. I think we're getting along really well on court. Lisa has the experience and wise words. It's been really fun. I think we're going to keep getting better and better."
The competition will get even tougher in the semifinals for Raymond and Robson in the form of Sara Errani and Roberta Vinci. The top-ranked Italians closed out their 61 64 defeat of seventh-seeded Bethanie Mattek-Sands and Sania Mirza by taking the final four games.
Now 21-3 on the year, Errani and Vinci are two wins away from their 17th WTA title as a duo and 20th as individuals. They are also both still alive in singles and will play quarterfinal matches Wednesday.
The doubles quarterfinals from the bottom half of the draw are also on Wednesday's schedule, with No.5 seeds Liezel Huber and María José Martínez Sánchez taking on Svetlana Kuznetsova and Flavia Pennetta, and No.3 seeds Nadia Petrova and Katarina Srebotnik squaring off with No.8 seeds Julia Goerges and Yaroslava Shvedova.
