Washington State is back in the NCAA postseason for the first time since 2010 after winning the Mountain West Tournament on Sunday evening, and the Cougars will open their regional slate Friday in Eugene with Mountain West Pitcher of the Year Nick Lewis taking the mound.
Lewis will start Friday at noon against Oregon State on + as part of the Eugene regional, a four-team, double-elimination bracket that includes host Oregon, Oregon State and Ivy League champion Yale.
The win that punched Washington State’s ticket was sealed in relief by Scott Rienguette, who threw 3 2/3 scoreless innings and struck out six to help close out the Mountain West title game on Sunday evening.
The numbers underline why this feels like more than a weekend victory for Washington State: the program had not reached the NCAA postseason since 2010, and the Mountain West Tournament triumph ends that drought with immediate consequences — a noon matchup with an Oregon State club that finished the regular season 43-12 and ranked 18th in the RPI.
Oregon arrives in Eugene as the regional host after finishing 40-16 and ranked 15th in the NCAA RPI. The Ducks are set to open Friday at 5 p.m. against Yale, which earned its spot by winning the Ivy League Tournament over Brown.
Yale’s profile in the bracket is starkly different: the Bulldogs sit 144th in the RPI, did not play a Quad 1 or Quad 2 game this season, went 3-6-1 in Quad 3 contests and 27-7 in Quad 4. That contrast creates a classic regional mismatch on paper, but the double-elimination format gives underdogs room to make it messy.
The regional also carries an immediate intra-state drama. Washington State split a two-game set with Oregon State at Bailey Brayton this season, losing the first game 18-0 in seven innings and rallying to win the second 7-6. Those results — a blowout and a narrow comeback — leave a clear fault line heading into Friday’s noon meeting on +.
There is friction around hosting, too. Oregon State finished with an independent record of 43-12 and 18th in the RPI yet did not land a regional in Corvallis, a fact that has left the program visibly upset and handed Oregon the home-site advantage for this bracket.
That combination — Washington State’s long-awaited return, Oregon’s strong resume, Oregon State’s hunger after being denied a host site, and Yale’s low-RPI but tournament-tested entry — makes the Eugene regional one to watch beyond simple seeding. For Washington State, everything narrows to Lewis’s start on Friday: his outing will determine whether the program can survive the opening squeeze and begin to press through a double-elimination format that punishes early losses.
If Lewis matches the expectations that earned him Mountain West Pitcher of the Year honors, Washington State has a live path through a loaded regional; if he doesn’t, the Cougars face the familiar pressure of a one-loss hole and a season-ending trip home. Either way, Lewis on the mound in Eugene is the single most consequential moment for a program playing its first postseason game in 14 years.
