Brian Walsh recorded a double-double with 14 points and 10 rebounds, while Zeke Marshall finished with 12 points and 10 boards for the Zips (1-2), who dropped their opener to Coastal Carolina before defeating Division III John Carroll on Monday.
Marshall opened overtime with a layup and added a pair of free throws to give Akron a four-point lead, but Forte buried a 3-pointer with under 90 seconds to play to trim the deficit to one.
After an empty possession from the Zips, Forte was fouled on a 3-point try and the freshman guard knocked down all three free throws to give Oklahoma State a 67-65 lead with 52 seconds remaining.
Alex Abreu then missed a layup at the other end and Smart converted a pair of free throws to give the Cowboys the decisive advantage.

A triple from Jake Kretzer cut the lead to two with 2:11 remaining and, after Brown missed a 3-pointer at the other end, Marshall drew the contact and finished the layup, but missed the potential go-ahead free throw to knot the game at 61-61 and send the game into overtime.
In the first half, a Brown 3-pointer gave the Cowboys a 30-23 lead late, but the Zips countered with the next six points and trailed just 33-32 heading into the locker room.
