Phoenix Mercury vs Golden State Valkyries Preview

With 10 games left to play, the Golden State Valkyries face a grueling schedule, with two games each against the Minnesota Lynx and the Mercury and a game against the New York Liberty.

They have surprised everyone this season, setting the record for most wins by an expansion team. However, Golden State’s bid for a playoff spot seems to be falling apart. The team finds itself in seventh, ahead of the Seattle Storm (17-18) in eighth by a game and a half. Any slip-ups during this final stretch could sink their playoff hopes.

The Phoenix Mercury are in a better position, holding the fourth seed, with four games separating them from the Seattle Storm (17-18) in eighth. Expect Phoenix to lean on Satou Sabally and Alyssa Thomas as they look to make a final push for a playoff spot.

Phoenix Mercury vs Golden State Valkyries Prediction

The Mercury are favorites to defeat the Golden State Valkyries at Chase Center. Heading into Tuesday’s game, Phoenix has split its last 10 games. Meanwhile, Golden State is 7-3 in its last 10. But the gulf in quality between both sides is too big to overcome with momentum alone.
