The No.8-seeded Makarova was the first of the two to take the court and she was the unfortunate one, dropping serve four times - and never getting a break point of her own - to lose to two-time Grand Slam champion Svetlana Kuznetsova in straight sets in just an hour and 10 minutes on the court, 6-2, 6-1.
The No.9-seeded Radwanska had a much better day, storming out to a 6-4, 3-0 lead and, after letting Lara Arruabarrena catch up to 3-all in the second set, closing out the Spanish wildcard, 6-4, 6-3.
"Clay is not really my favorite surface, and every win for me is a good win," Radwanska said. "I know Spaniards are very dangerous on clay, so I knew I'd have to run a lot today. We had a lot of good rallies. I think we had a really good match, so I'm happy I could win in straight sets today."
Other winners were Irina-Camelia Begu, who fought off double set point down 6-4 in the first set tie-break to beat Kurumi Nara, 7-6(6), 6-1, WTA Rising Star Sloane Stephens, who edged fellow American Bethanie Mattek-Sands, 3-6, 6-1, 6-4, Casey Dellacqua, who won a tight two-setter against Italian wildcard Francesca Schiavone, 6-4, 7-6(5), and Kaia Kanepi, who outslugged Madison Keys, 6-4, 6-3,
Badosa Gilbert, a 17-year-old Spanish prodigy, is now through to her second WTA main draw - she played Miami this year on a wildcard and made it to the third round before falling to Karolina Pliskova.
"I don't feel a lot of pressure - I just came here to have a nice time," Badosa Gilbert said. "I made it through qualifying now, and being able to play the main draw is just something great for me."
The press asked Badosa Gilbert what her dreams for the future are. "Normally I don't have ranking goals - I just try to do better and better in my tennis," she said. "But I'm dreaming of getting as far as possible in the WTA. I want to win Wimbledon. That's my dream. I would like to win Wimbledon."
