Elena Rybakina advances to semis in Rome

Seventh-seeded Elena Rybakina advanced to the semifinals by recording 10 aces and she ultimately prevailed Wednesday when top-seeded Iga Swiatek withdrew due to a right thigh injury in third set of their quarterfinal match at the Internazionali BNL d'Italia in Rome.

Rybakina's 2-6, 7-6 (3), 2-2 victory put her in the semifinals of a clay-court event for the first time in her career.

Swiatek appeared to injure her right knee at end of the second-set tiebreaker. After losing a point in which she changed directions quickly on back-to-back hits, the Polish star grabbed the knee and stood still for nearly 10 seconds.
