Oregon State made all the mistakes early, but costly ones from Hawaii late were the difference.

Rob Folsom drove in the go-ahead run on a sacrifice fly in the eighth inning and the Beavers came back from a three-run deficit to defeat Hawaii 10-6 last night in the season opener for both teams at Les Murakami Stadium.

A crowd of 3,168 witnessed an ugly game from the outset, as the teams combined for eight errors, five hit batters, three passed balls, a wild pitch and two catcher's interference calls on Oregon State's Andrew Susac in the same inning.

Eleven of the 16 runs scored were unearned.

Kevin Macdonald hit a grand slam and had five RBIs for the 'Bows, who dropped to 29-11 all-time in openers.

Stefen Romero, whose two-run homer in the ninth put the game out of reach, finished 3-for-5 with two doubles, four RBIs and three runs scored.

Oregon State scored seven unanswered runs after falling behind 6-3. The Beavers broke a 6-6 tie in the eighth inning after Hawaii center fielder Breland Almadova misplayed a fly ball at the wall in center, putting runners at second and third with one out. Reliever Lenny Linsky walked Dylan Jones to load the bases and Folsom drove a sacrifice fly to center that scored Carter Bell. A two-out wild pitch scored Parker Berberet to make it a two-run game as the Beavers took the lead despite only one hit in the inning.

UH trailed 3-2 in the fourth when the 'Bows loaded the bases on a Sean Montplaisir double and two catcher's interference calls. The second call put Greg Garcia on first, loading the bases with one out. Kolten Wong struck out swinging on a full count, setting the stage for Macdonald's two-out grand slam that cleared the fence in center.

Hawaii came out aggressive in the first inning, scoring two runs on only one hit. Garcia was hit by a pitch with one out and quickly stole second base. Wong lined a 3-2 pitch up the middle for an RBI single and UH took a 1-0 lead.

The Beavers' defense then came apart as Wong reached second base on a passed ball and advanced to third as Tyler Waldron's pickoff attempt bounced into center field.

Macdonald followed with a grounder to short, but Jared Norris couldn't scoop Bell's throw in the dirt at first as Macdonald was ruled safe on OSU's second error of the inning. Wong scored on the play to give UH a 2-0 lead.

David Freitas was hit by a pitch and Collin Bennett worked a 10-pitch walk to load the bases, but freshman Pi'ikea Kitamura bounced out to the pitcher to end the inning.

Oregon State took the lead in the fourth with back-to-back two-out hits off of Hawaii starter Nate Klein. Romero drove a 1-0 pitch to the wall in left field to drive in two runs and tie the game at 2. Klein fell behind Bell 1-0 and then served up an opposite-field base hit that gave OSU a 3-2 lead.

After UH went ahead 6-3, the Beavers tacked on a run in the fifth as Wong misplayed a two-out ground ball that allowed Brandon Hayes to score.

OSU added two more in the sixth as Romero doubled with one out and Bell was hit by a pitch, ending Klein's night. Jesse Moore came on in relief and drilled Hayes with a pitch, loading the bases. Pinch hitter Brent Warren laced an RBI single to left and Matt Boyd followed with a sacrifice fly to center to tie the game.

Klein finished the game allowing seven runs in 5 1/3 innings, but only two were earned. He walked none and struck out five.

Kraig Sitton picked up the win for the Beavers, allowing no hits and one walk while striking out two over the last 2 1/3 innings.
