The Kings maintained a double-digit lead through most of the third quarter and led 51-41 entering the fourth.
The Golden Eagles chipped away in the final quarter and got to within 53-47 with 5:57 remaining after two free throws by Jon Mauk.
But Keisling and Bixler hit four straight free throws in the one-and-bonus to push the lead back up to 10. Oak Hill later got back to within six with 3:03 left but again Keisling and Bixler hit their free throws down the stretch and the Kings led by as much as 18 points late.
The Kings were 14 of 15 from the line in the final 5:50 and 20 of 24 for the game.
When the Kings have the lead late they go to their weave. And with three strong ballhanders — Keisling, Bixler and Blake Hadley — they weave a deadly web for their opponents.
“They just kept battling back. If we wouldn’t have went to the weave, this would have been a close one clear to the end,” Kitchel said. “Our offense kind of broke down at the end and they were getting to the basket.
“When we get a lead and we get down to the weave at the end, we’re a good enough free-throw shooting team that we can finish it.”
Bixler scored 27 points and Keisling had 24 to lead the Kings. They were both 3 of 4 from 3-point range as Cass was 9 of 18 as a team.
“We attacked hard and kicked and we made some shots in the first half and it turned out good,” Bixler said. “My teammates made some good passes. All the credit goes to them.”
Ohman added six points and added a steal in the final three minutes when the game was still in doubt. His younger brother Evan Ohman added a big blocked shot in the fourth quarter that led to more Cass points. Hadley chipped in five markers.
