Jacob Sheldon-Collins’ throwing error allowed Cal Poly to score the tying run with two outs in the seventh inning and Mark Mathias followed with an RBI triple to give Cal Poly a 3-2 win over Hawaii on Saturday night at Baggett Stadium in San Luis Obispo, Calif.

For the second straight game, Hawaii (12-22, 3-5 Big West) scored first and took a lead of at least two runs into the sixth inning.

The Rainbow Warriors were ahead 2-0 in the seventh when Jordan Ellis scored from first on a groundout to the pitcher. He took off after Tyler Brashears made the throw to first and Eric Ramirez’s throw home was wide of Chayce Ka’aua at the plate.

Tommy Pluschkell followed with a grounder to short but Sheldon-Collins’ throw to first was in the dirt and Ramirez couldn’t scoop it out, allowing Ryan Drobny to score. Mathias followed with the triple to give the Mustangs (13-18, 3-2) the win.

Brashears (4-4) took the loss, giving up three runs (one earned) in 6 2/3 innings on five hits with one walk and seven strikeouts.

Kyle Smith (3-5) allowed two runs on eight hits with two walks and two strikeouts to earn the win. Danny Zandona earned his sixth save striking out three in the ninth. Zandona has struck out eight of the 10 batters he’s faced in the series.

Eric Ramirez hit a two-out RBI single and Marcus Doi followed with a run-scoring double for Hawaii’s two runs. 

Ramirez finished 2-for-3 with a walk and Alex Sawelson went 2-for-4 with a double.
