The Lions (4-14, 1-1 West Coast Conference), won for the first time at home in eight games this season and notched their first victory since December 8th. The Pilots (6-11, 1-1) dropped to 4-8 on the road.
Deadwiler, Johnson and Counts combined to score 33 of LMU's 46 second half points. Counts made six-of-six free throws in the final 1:28 to seal the victory -- the Lions first home win since February 2007.
Deadwiler's basket with 10:47 remaining gave LMU a 51-45 lead. Portland cut the Lions lead to 57-55 with 6:12 to play on a basket by Kramer Knutson but the Lions' defense stiffened and the Pilots didn't score another basket until just over a minute to play.
The Lions' win marked only the fourth time in the last 11 games LMU has beaten Portland.
