“Sancho was our top free-agent target outside our own roster and we are truly excited that she chose Phoenix,” said Mercury General Manager Jim Pitman. “The last two WNBA MVPs have been elite frontcourt players from Western Conference teams and their clubs have won championships. It takes elite defensive frontcourt players to compete with that, and to pair Sancho with Brittney Griner is ideal for us. Sancho has won everywhere she has played, our goal is to win a championship, and we are confident this move gets us closer.”
