Binghamton (14-13, 6-3) managed just six hits, but worked seven walks and took advantage of three errors spanning their six innings at bat.
The Bearcats lone hit of the tone-setting second inning was a two-run single by Tommy Popoff to cap the scoring, while Andrew Heppner finished the decisive fourth with a three-run home run.
Aidan Paradine accounted for the lone Siena (9-19, 5-10) run with a solo homer in the fourth. The Saints registered just three hits in the contest.
