CORVALLIS — John Tommasini drove in three runs and Michael Miller knocked in two more in his first start of the season as the Oregon State baseball team improved to 4-0 at Goss Stadium in 2009 by defeating Saint Mary's, 9-3, in the fourth game of a five-game homestand.

CORVALLIS — John Tommasini drove in three runs and Michael Miller knocked in two more in his first start of the season as the Oregon State baseball team improved to 4-0 at Goss Stadium in 2009 by defeating Saint Mary's, 9-3, in the fourth game of a five-game homestand.

Tommasini and Miller combined to go five-for-seven from the bottom two spots of the order and scored four of the Beavers nine runs.

"We got good production from the bottom part of our lineup, which has given us balance offensively as we are nearing the end of our homestand," Oregon State head coach Pat Casey said. "Sam Gaviglio had a good outing today and we got a good effort from our bullpen."

Adalberto Santos continued his hot hitting with an RBI single in the fourth inning that extended his hit streak to 12 games. Catcher Ryan Ortiz went two-for-four from the plate to give him a four-game hitting streak. Over those four games, Ortiz has hit .467 with five RBIs and five runs scored.

Stefen Romero also recorded two singles for his team-leading 10th multi-hit game of the season.

Former Ashland pitcher Sam Gaviglio received a win in his first start of his collegiate career, going five innings while allowing three runs. He did not walk a batter for the fourth time in five appearances and has only allowed one free pass all season. Gaviglio improved to 3-0 this season.

James Nygren came on in relief of Gaviglio and held Saint Mary's (13-10 overall) without a hit for two innings for his fifth scoreless outing of the year. Kraig Sitton and Kevin Rhoderick threw one inning each to finish the game off and combined to strike out five hitters in the eighth and ninth innings while allowing just two baserunners.

The Beavers (12-5) held a 6-3 lead going into the bottom of the seventh inning when Romero drove a pitch into left field and Brett Casey followed with a walk to put runners on first and second for Miller. The Oregon State left fielder proceeded to pull the ball into the right field corner on a grounder past the first base bag and raced around the bases for a two-RBI triple that put the game away for the Beavers.

Brandon Berl started for Saint Mary's and took the loss to drop to 1-1 this season. He lasted just three innings, allowing five hits and four runs.

WASHINGTON 5, OREGON 1 — At Portland, for the second straight game, Oregon outhit its opponent but failed to put runs on the board, falling to Washington in the third-place game of the inaugural Rose City Invitational at PGE Park.

Oregon (9-11) got behind early surrendering four runs in the top of the first. Freshman starter Madison Boer walked Washington's Brendan Gardner-Young to lead things off, and gave up an RBI-double off the wall in right center to Julien Pollard.

Boer, who struggled to find the strike zone early on, walked Pierce Rankin, but looked to regain his control after retiring Kyle Conley and Troy Scott. A two-run double to the wall in center from Aaron Russell kept the inning alive for the Huskies, and Jake Rife then singled to right to bring Russell home for the fourth run of the inning.
