Anhelina Kalinina rallied from a set down Thursday to record a 5-7, 7-5, 6-4 victory over Caroline Wozniacki in the second round of the Miami Open at Miami Gardens, Fla.
The 32nd-seeded Kalinina was trailing 5-2 in the second set and stood one point away from losing before saving the match point. She won that game as part of five straight to even the match at a set apiece.
In the third round, the Ukrainian won three of the final four games to cap the comeback victory in a marathon match that lasted 3 hours and 18 minutes.
Wozniacki, the former World No. 1 who recently came out of retirement, was plagued by seven double faults. Kalinina had a 5-1 edge in aces.
Kalinina's next match will come against the winner of Friday's expected matchup between second-seeded Aryna Sabalenka of Belarus and Spain's Paula Badosa.
Sabalenka's former boyfriend, Konstantin Koltsov, died earlier this week in Miami. The former NHL player was 42.
Miami-Dade Police Department called it an "apparent suicide" with no foul play suspected.
Sabalenka said earlier this week she plans to play in the tournament.
