"We've known each other for a long time and know each other really well," Muguruza said. "We practice together in Barcelona. She has what I don't have and vice versa."
Muguruza and Suárez Navarro first teamed up in Miami in March, and in their very first match knocked off doubles superstars Sara Errani and Roberta Vinci before eventually falling in the quarterfinals. Their next event saw them knock off another Grand Slam-winning duo, Hsieh Su-Wei and Peng Shuai, en route to a runner-up showing.
Muguruza and Suárez Navarro scored a win over former Wimbledon champions Kveta Peschke and Katarina Srebotnik during a semifinal run at the French Open - their first Grand Slam together. After a third round outing at Wimbledon, they picked up their first WTA doubles title last week in Stanford, getting past Paula Kania and Katerina Saniakova in a match tie-break in the final.
"We fought a lot and believed that we could win even when the score was tight," Muguruza said. "We play well together and will try to play all the tournaments that we can."
That title put the Spaniards in prime position to grab one of the eight berths for October's BNP Paribas WTA Finals Singapore presented by SC Global. They are currently tied for seventh place on the Road To Singapore leaderboard, with Errani and Vinci the only team already to clinch a spot.
"We first played together in Miami and played really well," Suárez Navarro said. "In the Stanford final, we started a little bit nervous, but are very happy to get our first title. We want to go to Singapore, but we need to do well in the rest of the US tournaments. It's not easy. We'll see what happens."
It is not outside the realm of possibility for Muguruza and Suárez Navarro to qualify for singles in Singapore too, as Muguruza currently is in 18th place on the singles leaderboard and Suárez Navarro in 14th place.
