Julia Riera of Argentina defeated Mexico’s Renata Zarazúa 6-4, 1-6, 6-2 on Wednesday to reach the semifinals of the WTA 125 tournament in Cali, Colombia, Infobae reported. The world No. 137 needed 2 hours and 10 minutes to get past Zarazúa, the second seed and No. 97 in the WTA rankings.

Zarazúa answered in kind in the second set: Riera again fell behind 0-4, and this time the Mexican held her advantage to win the set 6-1 and level the match. In the decider, Riera dropped serve early to go 0-1 down, but she broke in the second, fourth and sixth games, led 5-1, and after failing to close the match on her own serve, broke again in the next game to seal a 6-2 set and the victory.

Seventh career Top-100 win for the Argentine

Riera, a 137th-ranked player from Pergamino, defeated the 97th-ranked Renata Zarazúa to reach the semifinals. The quarterfinal victory over the second seed followed straight-set wins over local wildcard Valentina Mediorreal, 6-1, 6-1 in one hour and one minute, and Austria’s Julia Grabher, 6-2, 6-4, earlier in the week, according to El Tiempo de Pergamino and Diario Núcleo respectively.

The tournament, officially the WTA 125 Cali – Reto Win 2026, is played on clay at Club Campestre de Cali and offers $115,000 in prize money, El Tiempo de Pergamino reported. Riera’s week in Colombia is not limited to singles: paired with Spain’s Irene Burillo Escorihuela, she also advanced in the doubles draw to face the team of Dalila Jakupovic of Slovenia and Nika Radisic of Croatia, Diario Núcleo reported.

Giovannini’s run ends against US Open champion Andreescu

Riera is now the only Argentine left in the singles draw. Compatriot Luisina Giovannini, ranked 191st, lost to Canada’s Bianca Andreescu, No. 109, 6-1, 6-3 in the quarterfinals, Infobae reported. Giovannini had won two matches earlier in the tournament, including a 6-2, 6-3 victory over Jazmín Ortenzi, ranked 180th, before her exit.

Andreescu, born in Mississauga, Canada, reached No. 4 in the world in 2019, the season in which she won the US Open by defeating Serena Williams in the final, Infobae noted. With Giovannini’s defeat, Riera became the last Argentine standing; Match Tenis went further, describing her as the only South American player remaining in the tournament.

Semifinal opponent: Spain’s Leyre Romero Gormaz

The two semifinalists have never met before, and Romero Gormaz has dropped only one set all week, Match Tenis reported.
