Hall ran a pick-and-roll with Kris Brewer, who missed a shot at the end of regulation, for the critical play that gave the Golden Flashes (6-2) a 59-53 lead. The Trojans (4-4) followed with a basket by Ben Dillard, but it took three offensive rebounds to get there and only five seconds were left.
Chris Ortiz added a final free throw for the win.
Ortiz had a key sequence earlier, drawing a charge and then converting on the other end go put Kent State up 56-53 before the teams went scoreless for three minutes.
Devareaux Manley added 12 points for Kent State and Hall had eight rebounds.
