CORVALLIS, Ore. – Ryan Dunn’s run-scoring single with one out in the ninth gave the 19th-ranked Oregon State baseball team a walkoff win over No. 5 Arizona, 6-5, on Friday in the series opener between the clubs at Goss Stadium.
Tyler Smith opened the ninth inning by reaching on an error on an infield fly that was mishandled by Arizona first baseman Robert Refsnyder. He then stole second on a Michael Conforto strikeout.
Dylan Davis was intentionally walked in order to have Arizona reliever Matthew Troupe face Dunn, who took a 3-1 pitch and found a spot in the left center gap for the game-winning hit.
The win sent the Beavers to a 15-5 overall record and 4-0 mark in Pac-12 play, the best start to league for OSU since the 2005 club went 5-0.
Arizona, meanwhile, dropped to 16-7 on the year and 2-2 in Pac-12 games.
Ben Wetzler started for the Beavers and would have improved to 5-0 this season had Arizona not scored four runs over its last two innings to tie the game at five.
The left-hander worked 6 2/3 innings, scattering four hits and a run with seven strikeouts. He lowered his earned run average nearly a half-a-run, from 4.06 to 3.58, after the start.
Dunn’s game-winning single was his third hit and second RBI of the game. He was joined offensively by Tyler Smith and Ryan Barnes, who had each two hits to help pace the club to 11 overall.
Oregon State found itself down one after Arizona scored in the first on a single by Seth Mejias-Brean. The Beavers, however, jumped on Arizona starter Kurt Heyer for three runs in the bottom half of the inning.
Smith, the Beavers’ second batter of the inning, drove home the first run on a double to left, then scored when Dylan Davis found the whole between short and third. Davis then scored when Ryan Dunn doubled to the left center gap.
OSU added solo runs in both the second and third innings. Michael Conforto, who came into the game with a league-leading 26 runs batted in, drove in No. 27 with a sharp single to center. He watched in the next inning as Ryan Barnes drove in OSU’s fifth run of the game with another single up the middle.
Arizona tied the game with two in the eighth off OSU reliever Cole Brocker and two in the ninth off closer Tony Bryant. Bryant finished with the win after 1 2/3 innings in which he picked up two strikeouts.
The Wildcats tied the game on an infield single by Alex Mejia that scored two. Mejia led Arizona with three hits.
Stephen Manthei took the loss to drop to 3-2 this season.
Arizona started Kurt Heyer, who was touched for 10 hits and five runs in 6 1/3 innings.
