NEW YORK (AP) — Serena Williams has lost what is expected to be the last match of her transcendent tennis career. The 23-time Grand Slam champion was eliminated from the U.S. Open in the third round by Ajla Tomljanovic 7-5, 6-7 (4), 6-1 before an electric crowd at Arthur Ashe Stadium on Friday night. Williams turns 41 this month and recently told the world that she is preparing to retire. She has remained purposely vague about whether this appearance at Flushing Meadows definitely would be her final tournament. But everyone assumes it will be. Williams gave away leads in each set against the 46th-ranked Tomljanovic and bowed out of the singles bracket about 24 hours after she and her sister, Venus, lost in the first round of doubles.
