Billionaire Bill Ackman likes to win at everything, but professional tennis was a step too far.

The 59-year-old hedge fund titan made his pro-tennis debut Wednesday, entering a competitive ATP doubles tournament alongside four-time Grand Slam champion Jack Sock.

In a little over an hour it was all over, a straight-set defeat to Bernard Tomic and Omar Jasika. Former World No. 1 Andy Roddick, now a podcaster, described it as “the biggest joke I’ve watched in professional tennis.”
