Meehra Nelson tossed a one-hit shutout and Oregon State’s offense started fast in a 9-0 nonconference softball win over Portland State on Tuesday at the OSU Softball Complex.

Nelson struck out eight batters in five innings — the game was called due to the mercy rule.

The Beavers (22-18) plated five runs in the bottom of the first to provide Nelson with more than enough run support.

McKenna Arriola and Shelby Weeks both singled and Natalie Hampton was hit by a pitch to load the bases.

A wild pitch allowed Arriola to score and Lovie Lopez delivered a single that drove home Weeks for a 2-0 lead.

Stephanie Merwin followed with a three-run homer to left center — her second homer of the season — to put the Beavers up 5-0.

The Beavers added to their lead in the fourth, scoring four times to put the game away.

Alysha Everett, who was named the Pac-12’s player of the week earlier in the day, had a sacrifice fly to drive in Jessica Garcia. Sammi Noland then delivered a two-run single before a wild pitch capped the scoring,

The Beavers finished with eight hits — all from different players — with Merwin (three) and Noland (two) delivering the big hits.

Nelson's only blemishes were a third-inning single and a walk.

Everett, who has been on a tear, was named the player of the week after driving in seven runs to help the Beavers pick up their first ever series win over UCLA.

It’s the second weekly honor this season for the Beavers and the first for Everett.

Everett finished the UCLA series batting .625 as the designated player. Of her five hits, one was a double and another her seventh home run of the season. The seven RBIs, along with one more on Tuesday, bring her April total to 20.

Oregon State returns to Pac-12 action on Friday with a 3 p.m. start against Stanford.

The Beavers and Cardinal meet again at 1 p.m. Saturday and noon on Sunday.

Oregon State and Portland State will meet again on May 3 in Portland.
