World No 2 Iga Swiatek advanced into the third round at the Miami Open on Friday surviving a second set dip to beat France's Caroline Garcia 6-2 7-5.
Swiatek had beaten Garcia with ease at the same stage at Indian Wells earlier this month but she faced a little more resistance at Hard Rock Stadium.
Swiatek was 3-1 down in the second set and had to save a set point, when serving at 5-4 down before rallying to win the last three games.
"My energy level got down really fast. So I tried to wake myself up, keep the intensity from the first set, follow through and go for it," Swiatek said.
Swiatek lost to Mirra Andreeva in the semifinals at Indian Wells with the 17-year-old Russian going on to win the title.
Andreeva is in action later on Friday when she takes on fellow-Russian Veronika Kundermetova.
In the men's draw, fourth-seed Novak Djokovic faces Australian Rinky Hijikata while second-seed Carlos Alcaraz launches his bid against Belgian David Goffin.
