CORVALLIS — Ben Mount held on for the save with the tying run at second base in the bottom of the ninth to help the USC baseball team secure a 4-3 victory over No. 2 Oregon State on Sunday.

Logan Odom, a former North Medford High standout, earned the win for the Trojans (22-29, 12-12). He gave up just two runs on five hits with three walks and eight strikeouts in 61/3 innings.

Josh Osich took the loss for Oregon State (38-14, 17-7) after giving up three runs (two earned) in 52/3 innings on six hits. Osich walked four and struck out five as the Beavers suffered their first conference series loss this season.

Matt Foat put the Trojans ahead with a solo shot off Osich in the second inning, his first home run of the season. Andrew Susac walked to lead off the fourth and scored on Ryan Dunn's double to right center.

With two outs in the fifth, Joe De Pinto hit a double to help USC retake the lead.

The Trojans were able to manufacture another run with two away in the sixth.

Oregon State put runners at second and third with an out in the fifth before Odom struck out Kavin Keyes. After a walk to Susac loaded the bases, Odom got Jared Norris looking as another strikeout left the bases loaded.

Brian Stamps and Barnes hit back-to-back doubles in the seventh to make it 3-2, but Kyle Richter came in to relieve Odom and recorded two outs to keep the Trojans ahead.

In the top of the ninth, the Trojans loaded the bases and scored what proved to be the winning run when Ricky Oropesa hit a sacrifice fly to center.

Oregon hosts Oregon State at PK Park in Eugene at 7 p.m. Friday.

WASHINGTON STATE 8, OREGON 7 — At Pullman, Wash., Matt Argyropoulos' walk-off in the bottom of the ninth won the game and the series for Washington State in a back-and-forth thriller.

The Ducks (29-26-1, 8-16) entered the bottom of the ninth nursing a one-run lead with Madison Boer on the hill. The right-hander had Washington State down to its last out with pinch runner Kyle Johnson at third, but Adam Nelubowich drove a two-out double off the wall in right to score the game-tying run. With Nelubowich at second, Argyropoulos hammered his walk-off hit into deep center field.

Boer was credited with the loss, allowing two runs on four hits in 22/3 innings.

Oregon's Danny Pulfer appeared to win the game for the Ducks in the top of the eighth, with a two-run double to left that scored Kyle Garlick and pinch runner Dylan Gavin.
