CORVALLIS, Ore. – Andy Armstrong hit his first home run of the season and Adley Rutschman's seventh-inning grand slam helped send Oregon State to an 18-4 series-opening win over Washington State Friday night in front of 3,800 at Goss Stadium at Coleman Field.
Armstrong's solo home run came in the second and helped pushed the Beavers to a 7-1 lead after three full. Rutschman's grand slam – his second of the season and 14th overall home run – helped highlight the Beavers' nine-run seventh inning.
The 18 runs are the most for Oregon State in a conference game since defeating the Cougars, 19-9, in a three-game series finale in Pullman in 2008.
