Buoyed by nine second-half 3-pointers, Rochester broke open a close game and went on to down Jamestown, 101-89, in a Premier Basketball League game at Jamestown Community College on Sunday afternoon.

Corey Allmond led four RazorSharks in double figures with 30 points, including eight shots from beyond the arc; Jerice Crouch and Deverell Biggs each had 15 points; and James Helton chipped in with 10.

Jordan Bowling and Oswinn Hines paced Jamestown with 14 points apiece, Nathaniel Hill added 12 and Brandon Mcclester chipped in with 10 before a large crowd at the Physical Education Complex.

The Jackals trailed by only a point, 46-45, at halftime, but the Razorsharks hit several shots from deep early in the third quarter, which allowed the visitors to build a working margin which they maintained the rest of the way.
