Ryan Matranga hit a two-run single in the bottom of the ninth inning to cap a three-run rally for San Francisco, which evened the series against Hawaii with a 5-4 win today at Louis Guisto Field in Moraga, Calif.
Hawaii (3-5) led 4-2 with one out in the ninth when the Dons hit back-to-back singles off UH starter Kyle Von Ruden to chase him after 8 1/3 innings.

Lawrence Chew replaced Ryan and allowed the single to Matranga to give the Dons (1-7) their first win of the season.
Von Ruden allowed four runs — two earned — on seven hits with no walks and two strikeouts in the longest outing of his career.
Alan Baldwin drove in two runs and Alex Fitchett put Hawaii ahead 3-2 in the third inning with an RBI double.
Jacob Sheldon-Collins singled, walked twice and scored two runs and Eric Ramirez was 2-for-4 with a run and an RBI.
