The ball appeared to escape Simeon hands twice during the Wolverines' mad scramble, but Kendall Pollard eventually gained control and found D.J. Williams underneath for a dunk with 22 seconds to play.
Morgan Park swarmed Simeon during the fourth quarter in an attempt to take back the Chicago Public League Red-South battle Wednesday, but Simeon escaped with a 53-51 victory at Chicago State.
A fight broke out between the teams following the game, but it was broken up quickly.
Williams' dunk put Simeon ahead 52-49, and Morgan Park (16-2, 3-1) was called for a technical foul with 12.7 seconds to play because coach Nick Irvin called a timeout when the Mustangs didn't have any left. Jabari Parker missed two free-throw attempts, but Williams made 1 of 2 free-throw attempts after being fouled on the possession.
Morgan Park's Kyle Davis scored on a tip-in for the final score.
"We didn't come out with the energy like we (should have)," Irvin said. "We knew they couldn't take pressure, and it took us a while to get into it."
Simeon coach Robert Smith didn't speak to the media after the game.
Parker had 13 points and seven rebounds to lead the Wolverines (13-2, 6-0). Senior Russell Woods had 13 points, eight rebounds and two blocks, putting together one of his best games of the season in the face of rulings that declared three Simeon reserve players ineligible Tuesday. One of those players was Woods' friend and fellow transfer from Leo, Sean Moore.
DePaul-bound guard Billy Garrett Jr. scored 23 points, including a 3-pointer with 34 seconds to play to pull Morgan Park within 50-49. He also made a 3-pointer and followed with two free throws with 3 minutes, 17 seconds to play to cut Simeon's lead to 48-46.
Simeon wore about two minutes off the clock before Illinois recruit Kendrick Nunn hit a pull-up jumper with 57 seconds to play.
Simeon outworked Morgan Park on the boards for much of the first half to pull to a 26-23 halftime lead, and Woods showed the Wolverines weren't going to let up, scoring off a rebound to start an 8-2 third-quarter run.
