Serena and Venus Williams knocked out of US Open doubles by Lucie Hradecka and Linda Noskova

NEW YORK — In their first match together in over four years, and 25 years after their debut as a pair at the tournament, Venus and Serena Williams were unable to rediscover their signature magic and lost to Lucie Hradecka and Linda Noskova 7-6 (5), 6-4 in the first round of the US Open doubles on Thursday night.

In front of an adoring capacity crowd — the third in four days for Serena — that included Billie Jean King, NBA commissioner Adam Silver and Vogue editor Anna Wintour, the sisters had the primetime night slot on Arthur Ashe, something rarely seen in doubles. The pair clearly enjoyed playing alongside one another but struggled to find momentum after losing the tightly contested 72-minute first set in a tiebreak. After going down a break and falling into a 3-0 deficit to start the second set, they fought back to win three of the next four games, but it ultimately wasn't enough.

Hradecka even apologized to the crowd after the victory during an on-court interview, acknowledging it wasn't the result the fans wanted.

The US Open is expected to be Serena's final tournament before she «evolves» away from tennis. Venus told reporters earlier this week that it was Serena's idea to team up together one last time, jokingly calling her younger sister «the boss.» Together the duo has won 14 major doubles titles, including two in New York, and three Olympic gold medals. They had last joined forces at the French Open in 2018 and reached the third round.

Since Serena, 40, announced her impending departure from the sport with an essay in Vogue last month, fans have been flocking to catch a glimpse of the 23-time major champion in her matches and even during practice sessions. Both of her singles matches on Monday and Wednesday
