Beaver softball takes a pair from Portland St.

PORTLAND - Senior pitcher Marina Demore won her 19th game of the season while other Beavers climbed the single season charts as the Oregon State softball team took both ends of a doubleheader at Portland State on Tuesday night. The Beavers won, 7-2, in game one and took the nightcap, 4-3.

In game two, the Vikings jumped ahead with a three-run third inning to open the scoring. Oregon State began chipping away in its next at-bat. Freshman first baseman doubled home Elizabeth Santana on a ball into the right field corner to make it 3-1. Hampton now has 46 RBIs to move into a tie for third on the school's single season list. She joins Vanessa Iapala and Kelly Petersen at that mark. They both did it in 2004.

The Beavers (32-17) got their second run of the inning off a throwing error on a pickoff attempt. Senior Mollee Schwegler was at third pinch running for Desiree Beltran. Portland State tried to catch her off the bag after a pitch, but the snap throw to third got away to bring Schwegler home to trim the deficit to 3-2.

After leaving the bases loaded in the fifth, the Beavers fought their way ahead in the sixth. With Maggie Doremus at third and Lea Cavestany at second, designated player Ashley Sanchez beat out an infield single with two outs to tie the score. With runners at the corners, Santana hit the gap in left center to score Cavestany for a 4-3 OSU advantage.

Santana had two hits and three walks in the doubleheader, but she was a part of the biggest defensive play of the day, as well. In the bottom of the sixth with the tying run at first, a ball into the left center gap looked to be the potion to pull the Vikings even. Center fielder Hannah Bouska hit Santana with a perfect throw from the fence, and Santana fired a strike to catcher Ally Kutz to nail that potential tying run at the plate.

That would be as close as Portland State would come to tying the score, earning Demore her 19th win of the season. That ties her for 10th place on the single season wins list with Kelly Dyer (2008), Crystal Draper (1999) and Joan Harvey (1984).

Cavestany had five hits in the doubleheader, and her two-run homer in the seventh inning of game one put a capper on the Beavers' 7-2 win. It's her 10th homer of the season, making her and Hampton the first pair of Oregon State players with double digit home runs since 2007. That season, Cambria Miranda had 11 and Brianne McGowan had 10.

The two-run homer for Cavestany gave her 42 RBIs for the season. That moves her into ninth place on the school's' single season list, passing Santana's 41 RBIs from last year. It also gives the Beavers 48 home runs on the season, moving the team into a tie for fifth place with the 2004 squad.

The Beavers scored three runs in the second inning to answer Portland State's one-run first. Doremus scored with the bases loaded via throwing error on a fielder's choice attempt to force her out at the plate. Santana walked to force in the second run, and Beltran scored Cavestany on a fielder's choice later in the inning.

Hampton hit the first of her three doubles in the doubleheader to lead off the fifth. With Schwegler pinch running for her, Bouska also doubled off the top of the fence in center to drive her home.

Senior pitcher Tina Andreana won her fourth start in a row, limiting the Vikings to four hits while tying a season high with eight strikeouts. She allowed two runs, one earned.

The Beavers now travel to Eugene to face Oregon in a three-game Civil War set beginning Friday at 4:00 p.m.
