Teldric Ross scored 15 points and Octavius Reed added 13 to lead the Cougars in the win over Greenville.
Kylan Hill led Clifton Ridge with 23 points against Manchester.
“Manchester is a monster. They have huge kids who are very quick and fast,” coach Charles David said. “Greenville also had some big kids, but they weren’t as mobile, and we were able to drive inside against them. But we couldn’t stop Manchester.”
