The Tigers would have one more opportunity to tie the score after Zeglinski made just one of two foul shots with 19 seconds remaining, but Turner missed a 3 and Mike Scott hit two free throws with 5 seconds left to seal the win.
Hamilton had a career high 21 points for the Tigers (10-4), who had their winning streak end at seven games.
