Keys knocks out No. 1 Swiatek at Western & Southern Open
MASON, Ohio (AP) — American Madison Keys upset No. 1 Iga Swiatek 6-3, 6-4 on Thursday to reach the Western & Southern Open quarterfinals. Swiatek, a two-time Grand Slam champion, hasn’t gotten past the round of 16 in four tournaments since winning the French Open in June. The win was the 24th-ranked Keys’ first in six matches against a top-ranked opponent. She had never won a set against a No. 1 player. Keys is scheduled to next meet Wimbledon champion Elena Rybakina, who easily advanced with a 6-2, 6-4 win over Alison Riske-Amritraj.
