Danville (3-9, 1-1 45th District) grabbed the lead in the second quarter and wouldn't let go, holding off a run by host Boyle (2-9, 0-3) at the start of the second half and putting the game out of reach in the fourth quarter.
"In the last game against Lincoln County, in the third quarter I knew we could do things like this if we put it all together for four quarters," said Danville forward Darius Baughman, who had a game-high 18 points and 13 rebounds.
Boyle had won the last six meetings in the series, which made Friday's victory even sweeter for the Admirals.
"That's what really got me into it, knowing we were playing Boyle County," Baughman said. "That automatically gets you hyped."
Boyle coach Andy Moberly said that's understandable, but he said it's something his team doesn't fully grasp.
"I've seen it three times now this season with Lincoln (County) and Casey and Danville," Moberly said. "I asked our kids, 'Do you understand what it means to wear 'Boyle County' on your chest? Because in this area, who do they want to beat the most?'"
Cold shooting costs Boyle
The Rebels shot just 25.4 percent (18-for-71) from the field Friday and were 2-for-23 from 3-point range and 12-for-22 at the free-throw line.
"The thing I can't put my finger on is why we're not shooting the ball well," Moberly said. "I don't know how to make them a better shooting team. It's between their ears."
Pippen said the Ads were content to let the Rebels fire away from the perimeter.
"We wanted to keep them on the perimeter," he said. "Lucky for us they didn't shoot well from the perimeter, because that's the chance you take."
Boyle got plenty of chances to atone for its misses thanks to 23 offensive rebounds, but the Rebels got only 11 second-chance points. Danville had nine second-chance points from 13 offensive boards.
Danville outrebounded Boyle 50-46, and no one was bigger on the boards than Baughman, who had seven rebounds in the first quarter to help the Admirals get untracked after they fell behind 12-4.
Baughman also hit seven of 14 shots from the field in his best game this season.
"Darius can be as good as he chooses," Pippen said. "He's had this in him all along."
Phillip Dunn also had a double-double for Danville with 16 points and 12 rebounds, along with seven assists. Eric Caldwell added 13 points for the Admirals, who shot 45.1 percent (23-for-51) from the field.
Boyle's best scorer, Blake Jones, was held to just seven points on 3-for-15 shooting. He was 1-for-8 from 3-point range.
"We've got to have other people step up and focus on putting the ball in the basket," Moberly said.
Derek Vonckx led Boyle with 15 points and six rebounds, while Jones and Andrew Bertram had seven rebounds each.
Danville took a 22-14 lead with an 11-1 run in the second quarter, and the Ads pushed the lead to 12 by halftime.
Boyle scored eight straight points at the start of the second half to pull within 34-30, but a 14-4 Danville run soon made it 48-34, and the margin never reached single digits again.
"I think this will build some confidence," Pippen said. "Our kids understand if we work this hard and we continue to improve, the sky's the limit."
