Radwanska said she wasn't expecting such a tough challenge at the start of the match. She said Puig ''was playing with amazing intensity, I was really in trouble in that first set.''
She also had her left ankle treated by a trainer, but shook off any injury concerns, saying, ''pain is my second name.''

Lauren Davis was a little hungry after edging Maria Sharapova in a tight, second-set tiebreaker on Rod Laver Arena, so she decided to have a little snack in her courtside chair.
Some players go for a banana in those moments, but not Davis. She pulled out a jar of almond butter and ate a couple spoonfuls before starting the third set.
Davis said she needed an energy boost because she hadn't had lunch before the match. She says, ''I usually put the almond butter on the banana, but I thought that was a little too much this time.''
As for Sharapova, who won the third-round match 6-1, 6-7 (5), 6-0, she sticks to energy bars and gels for her on-court snacking.
She says, ''I don't do bananas anymore.''
Roberta Vinci has lost 6-0, 4-6, 6-4 in the third round of the Australian Open to Anna-Lena Friedsam in her first Grand Slam tournament since beating Serena Williams in the U.S. Open semifinals.
Williams' loss to Vinci ended her bid for a calendar-year Grand Slam in 2015, just two wins short after claiming the titles at the Australian Open, French Open and Wimbledon.
After producing one of the biggest upsets ever in women's tennis, Vinci lost in the final to fellow Italian Flavia Pennetta.
