CORVALLIS — Beau Day went 4-for-4 and drove in two runs to send the sixth-ranked Oregon State baseball team to an 8-3 win over Utah Saturday afternoon at Goss Stadium.

Dylan Davis and Tyler Smith each had two RBI as well to help pace the Beavers to the series win over the Utes. Oregon State has now won its first four conference series for the second time in the last three seasons. It's the third time under head coach Pat Casey as the Beavers' 2006 club did it first.

"We struggled offensively on Friday but today was a different day," Casey said. "We got contributions form the entire lineup, and when you couple that with Andrew (Moore's start), it's tough to beat."

Day singled four times to pace the club offensively as Oregon State (27-6 overall, 9-2 Pac-12) had 13 hits as a team. It was easily a season-high for Day, who came into the game with two hits on the year.

His singles came in the second, fourth, fifth and seventh innings. He drove in a solo run during the Beavers' four-run fifth and another in the seventh.

Tied at one after the top of the fourth, the Beavers pushed ahead in the bottom of the inning when Smith doubled down the left-field line, driving in two. OSU, highlighted by a Davis double that also scored two, broke the game open with its four-run fifth. Kavin Keyes also singled in a run during the inning, and scored when Day singled up the middle.

Oregon State sent eight to the plate in the fifth.

The Utes (14-16, 4-10) managed solo runs in the fourth, sixth and seventh innings.

Andy Peterson had three hits in the win and Davis had two.

Moore picked up the win to improve to 7-1 this season. The right-hander made the start for the Beavers and worked 62/3 innings, scattering five hits and three runs while striking out five.

In four appearances at Goss Stadium this season, Moore is 3-1 with a 2.42 earned run average.

Dalton Carroll, meanwhile, was saddled with the loss for Utah. He worked four innings in a start, allowing eight hits and six runs. He dropped to 3-3 this season.

OREGON 10, CALIFORNIA 4 — At Berkeley, Calif., Scott Heineman hit two of Oregon's four home runs and had four RBIs to lead No. 16 Oregon to an easy Pac-12 win at Evans Diamond.

Heineman, who entered the game with one career homer, became the first Duck to hit two in a game since Aaron Jones had two at UCLA on April 5, 2012. His four RBIs broke the career high of three he set last Sunday at Arizona State.

Heineman finished 3-for-5 with three runs scored and an RBI double. Ryon Healy was 2-for-4 with two RBIs and three runs scored, while Brett Thomas went 2-for-5 with two runs scored and a RBI.

Oregon (26-8, 11-3 Pac-12) jumped on the Golden Bears early scoring five runs in the first and three more in the second. Healy got the Ducks on the board in the first, hitting a line drive over the first baseman's head to score Thomas, who led off the game with a double.

Cole Irvin (7-1) picked up the win allowing four runs on seven hits in five innings.

NORTHWEST 5-4, SOUTHERN OREGON 4-3 — At Portland, Northwest University scored two eight-inning victories at Normandie Park in Portland.

In the first game, Ricki Tacdol's walk-off single clinched it for the Eagles (7-23, 4-12 Cascade). Southern Oregon (14-19, 10-10) fought back from a 4-2 deficit in the top of the fifth when Sierra Anderson singled home Stephanie Vandenbusch and Alexa Gonzalez to tie the game at 4-4.

NU's Kelli Peckham went the distance for Northwest limiting SOU four runs on six hits.

In the second game, the Raiders battled back once again after Northwest had taken an early 3-0 lead. Eagle pitcher Vanessa Ahrendt held the Raiders hitless through five innings, but Southern Oregon tied the game in the top of the sixth when Gonzalez tripled in Lauren Keel and Vandenbusch singled in Gonzalez before scoring on a single by Ashley Lowe. Vanessa Ahrendt got the win for NU, going eight innings, giving up five hits and three Raider runs.

Karlie Stephens took the loss for the Raiders in relief. She surrendered one run on eight hits in 61/3 innings of work.
