Nehemiah Jones led a balanced Callaway scoring effort with 15 points, with 11 of those points coming in the second period.
Pedy Leverette added 13 points, Terry Godwin scored 11 and Dre Martin contributed eight points.
The Cavaliers trailed 16-15 after the first quarter, but they were up 41-26 at the half, and they led 55-41 heading into the fourth period.
The Rebels hung tough for awhile, but the Cavaliers stretched the lead to 20 with a couple of minutes remaining, and head coach Terry Hayes emptied the bench.
“They’re a much-improved ball team from last time,” said Hayes, whose team beat Haralson 68-30 in the first meeting. “Turnovers hurt us tonight, and we fouled too much. But give Haralson County credit.”
