FRISCO, Texas (AP) Justin Johnson scored seven straight Western Kentucky points to open up a slim lead and the No. 3 seed Hilltoppers fought past second-seeded Old Dominion 57-49 in the semifinals of the Conference-USA Tournament on Friday.

Western Kentucky (24-9) takes on fourth-seeded Marshall (23-10) in Saturday's championship game.

The Hilltoppers led Old Dominion 47-44 with 3 1/2 minutes left when Johnson went up against the Monarch's leading scorer Trey Porter. Johnson made two free throws after being fouled by Porter, drove for a layup after rebounding a Porter miss, and answered Porter's dunk with a 3-pointer.
