CBS Sports reported 2.25 million average viewers for the Fever's victory Sunday over the Chicago Sky, a budding rivalry between the teams and rookies Caitlin Clark and Angel Reese.

The game peaked at about 3 million viewers, making it the most-watched WNBA game on any network in 23 years, CBS said.
