SPOKANE, Wash. (AP) — Silas Melson has struggled with his shooting at times this season, but not on Thursday night against Portland.

Melson scored a career-high 23 points, making seven 3-pointers, as No. 15 Gonzaga routed Portland 103-57 for their fifth consecutive win.

Melson hit 7 of 12 from 3-point range and Gonzaga shot 52 percent from the field while holding Portland to 30 percent.

Rui Hachimura added 20 points for Gonzaga (15-3, 5-0 West Coast), which has romped through the bottom of the West Coast Conference so far. Killian Tillie added 15.

“Rui is playing much better now,” Few said of the sophomore from Japan. “He’s not making silly mistakes and defensively he is much improved.”
