California, Mar 12 (UNI) China's Zheng Qinwen stormed into her first WTA 1000 Indian Wells quarterfinal with a decisive 6-3, 6-2 victory over Ukraine's Marta Kostyuk in Monday's fourth-round clash, marking her seventh career appearance in the last eight at this tournament tier.
The eighth-seeded Chinese star needed just 80 minutes to dispatch the 18th-seeded Kostyuk. "I needed to balance controlled aggression today," Zheng analyzed post-match.
"Kostyuk was more aggressive but she also had more unforced errors. I wasn't playing at my best level but it was enough for me to advance."
