BATON ROUGE, La. — LSU scored the first 11 points of the game and Arkansas never challenged as the Tigers used a huge first half to easily rout the Razorbacks, 75-56, Saturday at the Pete Maravich Assembly Center. Jonathon Modica’s layup stopped LSU’s 11-0 run at the 16:02 mark, but the Razorbacks didn’t score again until the 11:23 point, on another layup by Modica. By then, the Tigers had a 24-4 advantage, and it only got worse. Dionisio Gomez followed Modica’s score with a layup to give the Hogs consecutive scores, but the Tigers went on an 11-5 run to take a 35-11 lead. Alonzo Lane made two free throws with 3:39 left in the first period, but LSU (15-9, 4-8) poured it on and Brad Bridgewater’s short jumper with four seconds left in the half gave the Tigers a 49-19 lead at the break. LSU shot 55.2 percent in the period, made 15 of 17 free throws and forced 10 Arkansas turnovers. The Razorbacks (7-16, 2-10) were just six of 32 from the floor, 18.8 percent. “That has to be the worst 20 minutes of basketball I’ve ever seen,” head coach Stan Heath said. “I can’t explain why we didn’t show up or show any emotion. LSU had revenge on its mind, but it’s hard for me to give them a lot of credit because we weren’t here.” Arkansas beat the Tigers in Fayetteville on Jan. 22, 73-65. UA shot 49 percent in that game while holding the Tigers to 39 percent, and the Razorbacks had a 44-24 rebounding advantage. Arkansas played better in the second half, outscoring LSU 37-26, but the closest the Razorbacks got was within 18, 74-56 on a Wen Mukubu jumper with 12 seconds to play. UA shot 45.5 percent in the second half (15-33) while holding LSU to 39.1 percent (9-23), and had a 22-16 rebounding edge to actually win the battle of the boards, 42-38. The Hogs made just eight of 19 free throws for the game while LSU was 21 of 25. Forward Ronald Dupree, who had 12 points and five rebounds in the first meeting, had game highs of 25 points and 13 rebounds. He was seven of 13 from the floor and nine of nine at the line. Torris Bright had eight points, and Jaime Lloreda had eight points and eight rebounds. Freshman Kendrick Davis came off the bench to lead Arkansas with 16 points in just 21 minutes on six of 12 shooting. Gomez had nine points and Modica eight. Larry Satchell had a career-high matching nine rebounds. Arkansas plays a 7 p.m. non-televised game at Vanderbilt on Wednesday.
