Top-seeded Western Washington and third-seeded Seattle Pacific both won handily Friday to reach the semifinals of the NCAA Division II West Regional tournament at WWU’s Sam Carver Gym in Bellingham.

The GNAC regular-season champion Vikings rode the 29 points of guard John Allen to a 102-87 whipping of Chaminade while Jobi Wall, Cory Hutsen and David Downs combined for 59 points in the Falcons’ 85-59 defeat of Grand Canyon.

Other first-round games Friday saw Cal State San Bernardino beat Dixie State 75-69 and Cal Poly Pomona down Chico State 69-61.

Western (28-2), the defending national champion, will meet CSUB (20-8) in one tournament semifinal Monday while Seattle Pacific (26-3) will oppose Pomona (28-2) in the other.

SPU beat the Vikings last weekend for the GNAC tournament title, but was seeded third in the region behind Western and Pomona. CSUB was seeded fifth.

In the national rankings this week, the Falcons were No. 2 and Western was No. 4. The Vikings won both regular-season meetings with SPU before falling in the GNAC tourney title matchup.

At 7:30 p.m. today, Western’s top-seeded women and Mabton senior Trishi Williams will open regional play against Academy of Art from San Francisco.

The Vikings, 25-3 and ranked fifth nationally, won the GNAC regular-season and tournament titles. Williams was named MVP of the conference tourney.
