SLU continued its hot 3-pointing shooting as Liddell buried another three-ball at the 13:26 mark and Lisch banked in a 3-pointer with one second remaining on the shot clock to vault the Billikens to a 16-5 advantage at 11:58 of the first half.
Reed sandwiched a pair of free throws in between a Paul Eckerle 3-pointer and another 3-pointer from Liddell to put SLU on top 24-10 with seven minutes left in the frame.
Samford cut the deficit to 10 at 24-14 on a Josh Davis 3-pointer and free throws from Josh Bedwell and Bryan Friday. However, SLU answered with a Brett Thompson lay-in and a Lisch mid-range jumper to take a 28-16 lead into the final media timeout in the frame.

Samford turned on the shooting late in the stanza and ended up scoring at a 31-percent clip in the opening session.
SLU opened the second half on a 15-2 run, punctuated by a pair of jumpers by Thompson and a Kwamain Mitchell 3-pointer. Brian Conklin collected a Kyle Cassity pass and layed one in to put SLU on top 50-31 with 12:20 remaining in the game. A pair of free throws and a 3-point bucket by Lisch gave the Billikens a 22-point lead at 10:13, their largest of the night.
