PRINCETON, N.J. (Interstat) — James Beasley pitched six shutout innings and Jake Koonin delivered a two-run home run in the fifth inning to lead Princeton to a 5-1 victory over Siena on Wednesday afternoon at Bill Clarke Field.

Beasley allowed five hits and no earned runs while striking out one and walking two to earn the win for the Tigers, who improved to 14-24 overall. The right-hander’s outing was a bounce-back performance after he had allowed five earned runs in three innings against Wagner on April 22 and two earned runs in one inning against Penn on April 18.

Princeton broke a 1-1 tie in the bottom of the second inning on an RBI single by Grant Werdesheim, but the game’s decisive sequence came in the fifth. With one out, Werdesheim walked and then stole second base. Koonin followed by driving a pitch over the left-field fence for a two-run homer, giving Princeton a 4-1 lead. The Tigers added another run later in the inning when Brian Kaufman hit a sacrifice fly to center field, scoring T.J. Cernius.

Siena’s only run came in the seventh inning. With the score 5-1, Brandon Bergamotto singled through the right side to drive in pinch runner John Ramirez, who had reached on a single and advanced to third on a hit-by-pitch and a pickoff error. But the Saints were unable to mount a further rally, finishing with seven hits and stranding six runners.

Princeton also received strong relief work from Ethan Hsu, Charlie Wolf and Will Sword, who combined to allow one earned run over the final three innings. Hsu struck out one in a scoreless ninth.

The Tigers’ offense was led by Werdesheim, who went 2 for 2 with a walk, two stolen bases and two runs scored. Bennett Crerar also had two hits, both doubles, and Cernius singled and scored a run.

Siena fell to 16-24 on the season. The Saints got a solid two-inning relief outing from Ryan Lundari, who struck out three without allowing a hit. Evan Saulys started and pitched two scoreless innings before Matt Murtagh took over and allowed three earned runs in four innings.

Princeton took advantage of three Siena double plays and two sacrifice flies. The Tigers stranded six runners but capitalized on two Saints errors, scoring two unearned runs.

The game began with Siena taking a 1-0 lead in the top of the first when Bergamotto walked, advanced on a single by Nick Paradine and came home on a fielder’s choice. But Princeton answered in the bottom of the inning on a sacrifice fly by Kaufman.

The fifth-inning outburst proved the difference as Princeton’s bullpen held Siena to one run over the final four innings.

The Tigers, who had won two of three at Dartmouth over the weekend, improved to 3-4 in their last seven games. Siena had won three of its previous four, including a 7-4 victory over Massachusetts on Tuesday.

Princeton hosts Harvard for a three-game series beginning Saturday. Siena returns home to face Saint Peter’s in a three-game set starting Friday.

Interstat’s game simulator had projected a final score of Siena 6, Princeton 5, while Interstat’s ELO system gave Princeton a 66.20 percent probability to win.
