In the season opening contest, the Tigers overcame a slow start and a four-point halftime deficit by shooting 69.2 (18-of-26) in the second half and 52.6 percent for the game (30 of 57).
LSU committed only nine turnovers while forcing 20. The Tigers also out-rebounded EA Sports, 34-27.
EA Sports was led by former Florida State forward Anthony Richardson and former Southeast Oklahoma forward Anthony Walton who each had 10 points. The exhibition team shot only 37 percent from the field (17 of 46).
EA Sports scored the game's first eight points on a pair of three-pointers -- from the experimental 20-foot, 9-inch arc -- before the Davis' power layup gave the Tigers their first points of the game at the 16:25 mark.
Midway through the first half, LSU cut the lead to four, 17-13, on a tip-in of a missed three-pointer by redshirt freshman Tyrus Thomas and then a fast-break dunk by Darrel Mitchell off a steal by freshman point guard Ben Voogd.
LSU worked within three points after a dunk by reserve forward Magnum Rolle, but five straight by the exhibition squad included a three pointer by Robby Collum and a sleek give-and-go by Bernard Rock to push the lead to 29-21 with 2:46 to play in the first half.
The Tigers scored six of the half final eight points to trail 31-27 at the break.
LSU brought the game to a tie for the first time at 34-34, and earned their first lead of the game at 40-39 on a second-chance basket by Davis.
A pair of free throws and a three-pointer by Darrel Mitchell with just more than five minutes to play extended the LSU lead to 11, 59-48. Davis scored four more and the Tigers never looked back, leading by as many as 19 down the stretch after a 23-6 run.
LSU returns to action on Nov. 15 at 7 p.m. in an exhibition against a high scoring team from LSU-Shreveport.
