Venus Williams’ comeback is headed to the U.S. Open next month. She will enter the redesigned mixed doubles tournament with Reilly Opelka via a wild-card entry. The 45-year-old Williams returned to the tennis tour last week after more than a year away. She and Opelka were among the 14 teams announced Tuesday by the U.S. Tennis Association for its mixed doubles event on Aug. 19-20. Eight of the pairings received direct entry into the field based on having the highest combined current singles rankings. Six were given wild cards by the USTA. The players with spots in the bracket include nine who have won at least one Grand Slam singles title.
