Venus Williams made a quiet exit from the U.S. Open singles on Tuesday after losing 6-1, 7-6 (7-5) to Belgian Alison Van Uytvanck in front of a half-empty Arthur Ashe Stadium.

The subdued scene was in stark contrast to what unfolded on Monday, when a raucous star-studded crowd filled the world's biggest tennis venue to cheer on her younger sibling Serena to a 6-3, 6-3 win over Danka Kovinic in her Flushing Meadows opener, and then celebrated the 23-time Grand Slam winner's career.

Serena had signaled her intention to retire in a Vogue article in early August, saying she was "evolving away from tennis" but never confirming the U.S. Open as her final event.
