WNBA superstar Diana Taurasi allegedly took her frustrations out on a locker room door after losing to the Chicago Sky in the 2021 Finals … with the future Hall of Famer reportedly slamming it until it was completely wrecked.

The incident allegedly happened after the Phoenix Mercury lost 80-74 in Game 4 of the championship series — with the Sky securing its first title in franchise history.

According to The Next Hoops, Taurasi was apparently so pissed by the loss, she started banging the door … almost cracking it in half.

If it went down as reported, it’s a wild fit of rage from Taurasi, but it’s not the first time she had controversy this series — in Game 3, she shoved a referee while trying to help her teammate, Sophie Cunningham, get off the ground. The 10-time All-Star was fined $2,500.

There may be another fine coming soon … the Mercury players declined speaking with the media after the Finals loss, which could result in a financial penalty.

However, Mercury head coach Sandy Brondello did speak at the postgame press conference saying, “there’s a lot of disappointment in that locker room, as it should be.”

“But, I am proud how we worked just to get here.”

As for the Sky, Kahleah Copper was named Finals MVP and the champs had a huge rager with Chance The Rapper to celebrate!! Congrats on the huge win!!
