PULLMAN – Washington State baseball (17-29) posted a 10-2 series-clinching win over Air Force (18-30) at Bailey-Brayton Field on Sunday afternoon, according to a statement by Washington State Athletics.

The Cougars collected 12 hits as Ollie Obenour and Will Cresswell each homered to back pitcher Nick Lewis, who worked seven innings, struck out a career-high eight and did not issue a walk to earn the win. Obenour, Cresswell, Griffin Myers and Jack Weise each tallied two-hit games as WSU pulled away with a seven-run fourth inning. Cresswell tripled and homered while Obenour, Cresswell and Myers each drove in two runs.

Lewis only allowed a two-run homer in the fifth before Trevor Stowe worked a scoreless eighth, Jake Robinson retired the only batter he faced to start the ninth and Ingmar Hutzezon retired the next two hitters to seal the win.

Cresswell led off the second inning with a triple off the right field wall and scored on Griffin Myers' sacrifice fly to left field for a 1-0 lead. WSU pushed their lead to 2-0 after Johnstone doubled to right-centerfield that saw a Coug runner thrown out at the plate, but Johnstone moved to third on a wild pitch and scored on Cresswell's sacrifice fly to centerfield.

In the fourth inning, Jack Weise worked a walk and Kyler Northrop blooped a single into centerfield before Roy doubled to left centerfield that scored Weise and was misplayed by the centerfielder, allowing Northrop to score for a 4-0 lead. Obenour followed with an opposite-field two-run shot just inside the right field foul pole for a two-run shot and 6-0 advantage. WSU pushed the lead to 9-0 with a Griffin Myers RBI-bloop single down the left field line and two more runs came across on an Air Force fielding error.

Cresswell answered an Air Force two-run home run in the fifth with an opposite-field solo homer to right field in the sixth for a 10-2 lead.

The Cougars move onto preparing for their road game against Seattle U. The Cougs won two of three games in a weekend series back in March.
