During the game against the Washington Mystics this week, she showed that fiery side during a play on offense.

Lip-readers think they uncovered what a clearly frustrated Caitlin Clark said during the matchup when Ariel Atkins fell backward into Aliyah Boston following Clark attempting to create space to receive the basketball.

Less than a week after Clark made history with the first-ever triple-double recorded by a rookie in WNBA history, the Indiana Fever star could be seen going off on a ref after she was called for a questionable foul.

Clark picked up an offensive foul for pushing off of a Mystics defender. However, as she walked back to her side of the court, Clark could be seen yelling at the referees about the call, as she appeared to tell them, “Don’t fall for that. No, you fell for it.”

She also called the opponent ‘soft.’

Clark ended the game with 29 points, 13 rebounds, and five assists, however, Indiana Fever lost to Washington 89-84, according to the New York Post.

The loss dropped the Fever to 9-14 on the year.
