Marcus Denmon saw the opening on the fast break on a previous trip downcourt. With No. 8 Missouri getting all it could handle from Old Dominion and just over a minute left, he went there again. Denmon scored 17 of his 19 points after halftime and hit the go-ahead 3-pointer with 61 seconds to play Friday night as the Tigers survived a scare with a 75-68 victory over the Monarchs.
