Carlos Alcaraz and Iga Swiatek, the top-ranked players in tennis, got past adverse weather conditions and challenging opponents on to reach the Western & Southern Open quarterfinals. Alcaraz overcame two rain delays totaling 2 hours, 35 minutes and 14th-seeded American Tommy Paul, who beat him last Friday in the Canadian Open quarterfinals, for a 7-6 (6), 6-7 (0), 6-3 win Thursday in a match that lasted 3 hours, 9 minutes. Swiatek adjusted to a stiff wind and came from behind to advance to a matchup with 10th-seeded Marketa Vondrousova of the Czech Republic with a 3-6, 6-1, 6-1 win over China’s Zheng Quiwen.
