Carson, Calif. — Two-time Olympic gold medalist Claressa Shields of Flint defended her middleweight titles with a dominant unanimous decision over Belgium’s Femke Hermans on Saturday night.

Shields won every round on every scorecard to improve to 8-0 in her two-year pro career in the opening fight of the last HBO boxing telecast.

Cecilia Braekhus also defended her welterweight titles with a dominant unanimous decision over Aleksandra Magdziak-Lopes in the main event.

A small, chilly crowd at the famed outdoor arena at StubHub Center south of downtown Los Angeles witnessed the final show in the 45-year history of HBO’s boxing coverage.

The premium cable network has been a driving financial force behind the sport for decades, but its management has decided to bow out of the game amid stiff competition from Showtime, ESPN and new streaming service DAZN.
