Top-ranked Iga Swiatek survived in her return to hard courts Wednesday night in the Cincinnati Open, outlasting Varvara Gracheva 6-0, 6-7 (8), 6-2. Playing for the first time since finishing third for Poland in the Paris Olympics on clay, Swiatek set up a third-round match against Marta Kostyuk — a 6-3, 7-5 winner over Lulu Sun. “For sure, the transition is probably the hardest, from like the slowest surface to the fastest surface,” Swiatek said.
