CORVALLIS — Tanner Robles turned in a dominant performance, striking out seven in 72/3 innings, and Lonnie Lechelt went 3-for-4 as the Oregon State baseball team defeated No. 23 Arizona 4-3 on Saturday afternoon at Goss Stadium.

"It was a great atmosphere this afternoon and Tanner threw an absolutely great game," Oregon State coach Pat Casey said. "He was very effective. Lonnie and the rest of the offense really responded with 10 hits and we came through defensively as well."

Robles picked up his third win of the season with the longest outing of his career, going 72/3 innings while allowing just two runs on two hits, and letting only five Arizona (28-12, 7-7 Pac-10) hitters to reach base. Robles also struck out a career-high seven while not allowing any walks.

Lechelt, meanwhile, collected three hits for the third time this season. He singled and scored in the second, doubled in the sixth and reached on an infield single in the eighth.

Chris Hopkins continued his hot hitting in this series, picking up another hit to extend his streak to five games. Hopkins' on-base abilities proved crucial for the Beavers as he scored two of Oregon State's (19-14, 7-7 Pac-10) four runs.

Eric Ammon and Ryan Ortiz both drove in runs for the Beavers.

Kevin Rhoderick picked up his eighth save of the year, pitching 11/3 innings to lock down the win for the Beavers.

Lechelt got the Beavers started on the day by singling into right field with one out in the second. After a wild pitch advanced him to second, Ammon followed up with his first double of the season, scoring Lechelt and giving the Beavers a 1-0 advantage.
