WSU baseball tied No. 3 Oregon State University 7-7 Sunday in a game that was stopped in the top of the 10th inning due to lightning.

It was the first tie for WSU since 1992 and first in a conference game since 1936.

The Cougars (14-25-1) jumped on OSU (35-7-1) sophomore right-handed pitcher Grant Gambrell for five runs in the bottom of the first inning.

WSU recorded five hits in the inning and were helped by two throwing errors by the Beavers. Senior outfielder Blake Clanton recorded an RBI with a sacrifice fly and sophomore outfielder Danny Sinatro drove in two more runs with a bases loaded single to right field.

Junior right-handed pitcher Parker McFadden started on the mound for WSU. He lasted three and one-third innings, allowing one run on one hit while striking out four Beavers.

Sophomore right-handed pitcher AJ Block took over for McFadden with runners on second and third with one out in the fourth innings. Block got two batters to strike out swinging to escape the inning.

Block worked out of another jam in the fifth inning. After runners reached first and second with one out, he got a double play on a groundball to junior infielder Andres Alvarez to end the inning.

OSU junior outfielder Trevor Larnach began the top of the sixth with a solo home run off Block to cut the Cougars lead to 5-2.

The Beavers threatened to score again with runners on first and second and one out, but senior right-handed pitcher Ryan Walker forced an inning ending double play.

Clanton snapped a four-inning hitless streak for the Cougars in the sixth inning with a leadoff solo home run to right field, his sixth of the year.

The Beavers scored five runs in the top of the seventh inning to take the lead for the first time in the ballgame. Walker allowed six singles, two fielders choices and a walk as OSU took a 7-6 lead.

WSU answered in the bottom of the inning with a run of its own. Sophomore infielder Dillon Plew walked and reached third base on a single by Alvarez. Junior infielder Justin Harrer followed with a single to center to bring home Plew and tie the game at seven.

The game remained deadlocked for the eighth and ninth innings. The wind, which began to pick up in the sixth inning, changed from breezy to blustering as dark clouds moved in overhead. The game was called at the top of the 1oth inning with a runner on first base and the teams still level.

WSU will look to end a four-game winless streak 5 p.m. Friday against University of Southern California at Bailey-Brayton Field.
