Thomas is no stranger to putting up triple-doubles. She entered the playoffs with a league-leading 23 triple-doubles over her 12-year career—no other player has more four. This was the fifth postseason triple-double of her career.
Chants of “MVP” rained down on the court as Thomas closed out the game from the free-throw line for the Mercury and officially sent home the reigning champions. Her teammates clearly agree with the assessment of the crowd.

With the win, the Mercury advance to the WNBA semifinals, where they will face off against the Minnesota Lynx. Game 1 of the best-of-five series tips off on Sunday.
