The Portland State Vikings tuned up for the Pacific Coast Softball Conference championship series with a 1-0 home victory Tuesday over Oregon State.

Former Beaver Karmen Holladay, a junior from Corvallis, hurled a complete-game three-hitter as the Vikings snapped a nine-game losing streak in the series.

Holladay, who transferred to PSU last fall after three years with OSU, ran her scoreless innings streak to 18 innings and improved to 2-0.

Oregon State (18-26) got a hit in each of the first three innings, but the Vikings' defense - led by shortstop Arielle Wiser - turned away the Beavers with several key plays.

PSU had four hits, all off OSU starter Tina Andreana (5-15), who went five innings. Leadoff batter Jenna Krough went 2 for 3 for the Vikings, who scored on Carly McEachran's RBI single in the fourth inning. Her hit scored Crysta Conn, who led off the frame with a double and moved to third on a sacrifice bunt by Danielle Lynn.

Portland State (32-16) won for the ninth straight time. The Viks are 19-1 in their last 20 games.

PSU will play host to Loyola Marymount Friday and Saturday at Erv Lind Stadium in a best-of-three series for the PCSC title and an automatic berth into the NCAA tournament.
