LONDON (AP) — Madison Keys was stunned in straight sets by 37-year-old qualifier Tatjana Maria in the Queen’s Club semifinals on Saturday.
Maria, a German mother of two, beat Keys 6-3, 7-6 (3) for her first career victory in four meetings with the reigning Australian Open champion.
Queen's is a grass-court tournament players also use to prepare for Wimbledon later this month.
Maria, ranked 86th, toppled the eight-ranked American, who hit 10 aces but failed to get a break.
Maria will face either Olympic champion Zheng Qinwen or the eighth-seeded Amanda Anisimova in the final.
Maria has three career titles, with her last coming in 2023 at Bogota.
