SURPRISE, Ariz. -- The freshman tandem of Dylan Davis and Michael Conforto helped Oregon State break a 4-4 tie in the eighth inning of the Beavers' 9-4 win against Winthrop on Friday at Surprise Stadium.

Conforto drew a four-pitch walk from Winthrop reliever Michael Gilroy in the eighth with the bases loaded for the go-ahead run. Davis then drove a single down the left-field line, scoring two, to highlight the Beavers' five-run inning that sent them to their sixth win of the season.

The Beavers (6-4) scored five runs in the eighth to break open the game, with Ryan Dunn contributing his second of two sacrifice flies. OSU also scored on an error from a Danny Hayes sacrifice bunt.

Conforto saw his hit streak end at five games. Davis, meanwhile, posted his third multi-hit game of the season and finished 2-for-5.

The Beavers' rapped out 10 hits, with Davis, Ryan Barnes and Jake Rodriguez tying for the team lead with two. Conforto, Davis and Ryan Dunn drove in two runs.

Tony Bryant, who came on in the eighth and forced Winthrop to strand runners on the corners, got the win to improve to 2-0.

Gilroy gave up three hits and five runs in one inning and took the loss for Winthrop (1-9), dropping to 0-1.

The teams traded runs in the bottom of the seventh and top of the eighth. The Beavers broke a 3-3 tie when Dunn hit a sac fly in the seventh, but the Eagles managed to tie it in the eighth when Matt Lobacz grounded out to second, scoring Jason Driver.

The Beavers held a 3-0 advantage after six innings but Winthrop tied the game with three runs in the top of the seventh. Patrick Gamblin tied the game with a single that hit OSU starter Dan Child and deflected into right-center. Max Gordon made a heads up play and forced out Gamblin at second as he went for a double but not before the Eagles managed to score two to tie the game.

Rodriguez put the Beavers on the board in the second. Dunn hit a two-out double to left and scored when Rodriguez singled sharply to left off Winthrop starter Eric Ruth.

Oregon State added to the lead in the third when Conforto flew out to deep center for a sacrifice fly that scored John Tommasini, who had walked earlier in the inning.

The Beavers added another run in the sixth, scoring when Gordon, pinch hitting for Joey Matthews, executed a squeeze that enabled Hayes to score from third.

Child made his third start and worked a career-long seven innings. He gave up three hits and three runs -- all unearned. He struck out a career-best eight while issuing two walks.

Ruth went 5-1/3 innings in the start for Winthrop, and did not figure in the decision after the Eagles tied the game in the seventh. The righty allowed five hits and three runs while walking five and striking out five.
