EUGENE, Ore. (Interstat) — Trey Morris pitched 6 2/3 innings of no-hit baseball and Jacob Galloway drove in five runs as Oregon State defeated Washington State 10-1 in a playoff game Sunday evening at PK Park.

The Beavers, who improved to 45-13, broke the game open early with a five-run second inning and never looked back. Morris struck out nine and allowed only one earned run on zero hits before leaving with one out in the seventh inning. Washington State’s only run came in the bottom of the seventh on a double by Trevor Smith that scored a runner who had reached on a walk and advanced on a groundout.

Oregon State pounded out 15 hits and scored in five different innings. Galloway went 4 for 4 with a walk and five RBIs, including a two-run single in the third inning that extended the lead to 7-0. Catcher Josh Proctor added two hits in three at-bats, including a double, and scored three times. Second baseman AJ Singer had two hits and an RBI, and Easton Talt drove in two runs while going 2 for 4.

Washington State, which fell to 31-28, managed seven hits but stranded eight runners. Smith drove in the Cougars’ only run with his double in the seventh, and designated hitter Spencer Hartman had two hits. The Cougars used five pitchers, with starter Brock Blatter taking the loss after allowing four hits and one earned run over four innings, striking out four.

The game began with Oregon State starter Morris in complete control. He retired the first two batters of the game on a flyout and a strikeout before allowing a single to Hartman. He then struck out Priest to end the inning. Morris worked around a walk and a hit-by-pitch in the second inning, striking out two more to escape a bases-loaded jam.

The Beavers’ offense gave him all the support he needed in the second. Proctor walked, advanced on a bunt single by Haight, and scored on Galloway’s single through the right side. Galloway then stole second, and after a groundout, Inge walked to load the bases. Talt walked to force in a run, and Singer singled to shortstop to drive in two more, making it 4-0. A flyout ended the inning but Oregon State had seized momentum.

In the third, Oregon State added four more runs. Vazquez singled, Proctor doubled, and after a groundout, Galloway singled up the middle to drive in two. Krieg doubled, Galloway scored on Inge’s single, and Talt hit a sacrifice fly to bring home Krieg. The lead grew to 8-0.

Morris continued to dominate. He retired the side in order in the fourth and fifth innings, striking out two more. Washington State’s first hit off Morris came in the fourth when Robinson singled, but a fielder’s choice and two groundouts kept the Cougars off the board.

The Beavers tacked on another run in the fourth when Porter scored on Galloway’s third RBI single. In the eighth, Vazquez scored on a sacrifice fly by Galloway, and a throwing error allowed an unearned run to score, making it 10-0.

Washington State finally broke through in the seventh. Obenour singled, advanced on a bunt groundout and a groundout, and scored on Smith’s double to left center. Tanner Douglas relieved Morris and got the final out of the inning. Douglas pitched 2 1/3 scoreless innings, striking out two and allowing no hits.

Oregon State’s Tanner Haight moved from the outfield to left field in a defensive shift, and the Beavers closed out the game without further damage. The Cougars put two runners on in the ninth on a single and a walk, but Douglas struck out Northrop to end the game.

The victory avenged a 3-2 loss to Washington State on Friday, May 29, and gave Oregon State its third win in the last four meetings between the teams. The Beavers also defeated the Cougars 18-0 on April 6 and lost 7-6 on April 7.
