Teodora Kostovic vs Kaitlin Quevedo Preview

Teodora Kostovic is coming off a straight sets win over Darja Semenistaja, which took 17 games to decide. Kostovic edged out a tight first set 6-4 in 48 minutes, but the second set was largely one-sided as the Serbian rounded out an emphatic 6-4, 6-1 win in an hour and 18 minutes. In the victory, Kostovic hit 1 ace and committed 3 double faults. She landed 50% of first serves in play and won 69% of first serve points (18/26).

Kostovic won 62% of second serve points (16/26) and saved five of six break points in the match. The 19-year-old is through to her first WTA Tour quarterfinal, having also beaten Victoria Luiza Barros earlier in the tournament. Kostovic improves to 32-22 for the season at all levels, and is expected to rise up to 158th in the rankings at the very least.

Kaitlin Quevedo is also through to her first WTA Tour quarterfinal. Quevedo beat 16-year-old Brazilian wild card Leme Da Silva in straight sets to progress. Quevedo dominated the match from start to finish against her inexperienced opponent. She rallied from a break down to win the first set 6-2 in 33 minutes. She led 4-0 in the second set when she momentarily dropped her serve, but quickly regained her composure to break again and seal victory in her next service game. 

In the victory, Quevedo hit 1 ace and 3 double faults. She landed 58% of first serves in play and won 63% of first serve points (22/35). Quevedo won 52% of second serve points (13/25) and saved three of five break points. Quevedo improves to 36-19 for the season, having beaten Tikhonova earlier in the tournament.

Teodora Kostovic vs Kaitlin Quevedo Prediction

Neither player has dropped a set on their way to the quarterfinal of the Sao Paulo Open, with Quevedo perhaps showing more ruthlessness with two emphatic scorelines. Kostovic’s win over Semenistaja was impressive, though, suggesting this is going to be a tough assignment for Quevedo, who, despite her better hard-court resume, will need to dig deep for a result.
