MASON, Ohio (AP) — Four-time Grand Slam champion Naomi Osaka was eliminated by Shuai Zhang, 6-4, 7-5, in the first round of the Western & Southern Open. The tournament outside Cincinnati lost another big name, Coco Gauff, when she retired from her match against qualifier Marie Bouzkova with a left ankle injury. Gauff had her ankle taped after the first set and dropped out after the first game of the second set. The marquee match scheduled for Tuesday night at this hart-court U.S. Open tuneup was Serena Williams against Emma Raducanu, last year’s champion at Flushing Meadows. Williams announced last week that she is transitioning away from tennis.
