A win Friday assures Oregon State of no worse than a tie for the Pac-12 crown. The first pitch is scheduled for 4:05 p.m.
Oregon and UCLA trail the Beavs by two games in the Pac-12 standings.
Oregon State is 43-9 overall, with a 22-5 mark in Pac-12 play. Washington State (21-30, 8-19) has been in a tailspin, losing 10 of their last 12. They are 7-15 on the road on this season.
WSU can put runs on the board but they've struggled with their pitching, especially in later innings.
Matt Boyd (10-3, 2.15) is expected to get the start for the Beavs on Friday.
This weekend's games are scheduled for 1:05 p.m. Saturday, and 12:05 p.m. on Sunday.
The Beavers have a microscopic 2.02 team ERA headed into the weekend.
Oregon State is also 20-3 at home this season.
The Beavs are rated No. 3 in the nation by USA Today and Collegiate Baseball and No. 4 by Baseball America. OSU is also No. 4 in the nation in the NCAA RPI.
Oregon State is a virtual lock to host a four-team, double-elimination regional next week.
And they seem all but assured of hosting a super regional if they advance through the regional. Eight teams emerge from the super regional to the College Baseball World Series in Omaha.
The regional pairings will be announced on Monday -- the selection show is slated for 9 a.m. and will be broadcast on ESPNU.
New Zealand's top baseball prospect, pitcher Makauley Fox, has committed to Oregon State, according to New Zealand's Stuff website. Fox turned down a number of MLB offers in favor of Oregon State. The 6-3 lefty pitched in November jumped onto the radar after he tossed five shutout innings for the New Zealand Diamondblacks against Thailand in the World Baseball Classic qualifiers.
