Ninth-seeded Westmont upset top-seeded Arizona Christian, 75-63, in the quarterfinals of the Golden State Athletic Conference Tournament on Thursday at Hope International.

Ajay Singh followed up Wednesday night’s 25-point performance by once again leading the Warriors, this time with 21 points. Nate Meithof was close behind with 17 points of his own, and Jared Brown, who made three shots from beyond the arc, added in 11 points.

Jalen Townsell, who scored nine points, led the Warriors in the rebound battle with 10 of his own.

The Warriors made 30 of 58 shots (51.7%) and held Arizona Christian to a 37.9% clip from the field (25-66).

“It’s crazy to think that we have had three practices all year with our full squad,” said coach Landon Boucher. “Tonight was just our third game all season being as full strength as possible. Right now, we’re rolling with what we have and making the best of it.

“The guys are having a lot of fun together and I’m really proud of them.”

Westmont will play Ottawa University of Arizona in the semifinals.
