Marcus Prigge recorded his third double-double in four games with 21 points and 21 rebounds. He also had three assists and two blocks in Stockbridge's victory.
"He just did it all," Stockbridge coach Joe Wenzel said. "I can't remember the last time I saw a kid with 21 points and 21 rebounds. We did have good contribution from everyone. The guards closed out the game and knocked down some free throws."
Kaleb Grammer and Jonathon Mason each scored 12 points and Skeeter Ballagh had 10 points in Stockbridge's win.
Stockbridge led 17-16 after the first quarter, and it outscored Jackson Northwest 19-11 in the next eight minutes to widen its lead.
"Our intensity was a little better than it has been. We took good care of the ball and only had 12 turnovers," Wenzel said.
Jackson Northwest's Malik Greene finished with 18 points, and Josh Kelly had 10 points.
"We got into a little bit of foul trouble and we're not very deep right now because of injuries," Jackson Northwest coach Justin Brown said. "And they started to go on a little bit of a run. We missed four out of six free throws in the fourth quarter and most were front ends of a one-and-one. Free-throw shooting has hurt us all season and tonight was no different."
