Pershing Square founder Bill Ackman made his professional tennis debut. In a doubles match at the Tennis Hall of Fame Open, he and his partner lost in straight sets in a match that lasted just 67 minutes. Some tennis greats were sharply critical of the match.

"Bill Ackman used his vast wealth to worm his way into a professional, ATP-sanctioned tennis tournament at the Hall of Fame at the age of 59," journalist Glenn Greenwald posted on X. "His level was so abysmal that it forced the professional players on the court to pat the ball to him, enraging the tennis world."
