LSU (11-17, 3-10 Southeastern Conference) snapped a 10-game losing streak, dating back to a Jan. 12 victory over Arkansas. The Tigers ended their misery by scoring their most points since a season-opening win over Northwestern State.
Mississippi State (14-13, 6-7) lost despite shooting 56 percent from the field (28 of 50) and outrebounding LSU 38-32. Riley Benock missed an 18-foot jumper at the buzzer that would have tied it.
LSU trailed by 13 early, but used a 25-8 run to take a 45-41 lead by halftime. The Tigers shot 8 of 14 (57 percent) from 3-point range in the first half.
LSU ended more than month of losses thanks to an offensive explosion compared to past games. The common theme during the 10-game losing streak was an anemic offense that never scored more than 61 points and averaged just 54.5 points per game.
But LSU pushed past the 61-point mark with more than 12 minutes remaining, and five players finished in double figures. Ralston Turner and Garrett Green both scored 12 points and Andre Stringer added 10.
LSU forced 18 Mississippi State turnovers.
LSU stretched its lead to 63-53 on a Warren layup with 12:01 left, but Mississippi State stayed close, tying the score at 77 on Sidney's fast-break layup with 1:41 remaining.
Green tipped in an offensive rebound with 1:17 remaining to give LSU a 79-77 lead and the Tigers held on the rest of the way. Benock's look was clean as time expired, rattling around the rim before finally falling to the floor.
Mississippi State has lost four of its last seven and fell into a tie with Arkansas for second place in the SEC's Western Division. The Bulldogs lost for just the third time in the past 11 games against the Tigers.
