Sue Barker believes "tennis was the loser" in a controversial US Open final - but said Serena Williams had a point when she criticised the umpire.
A series of incidents, which included the beaten American calling Carlos Ramos a "liar" and a "thief", saw Williams penalised twice.
Afterwards the American said it was "sexist" to have been penalised a game.
"The umpire was following the rules by the book but Serena has a point," said BBC Sport tennis presenter Barker.
Williams, who was beaten 6-2 6-4 by Naomi Osaka in New York, was given a code violation for coaching, followed by a penalty point for racquet abuse and finally a game penalty after accusing the umpire of lying.
