The Tigers return to the SEC slate Saturday at 1 p.m. when they host Ole Miss (9-4, 0-1).
LSU shot an eye-popping 70.3-percent from the floor, a new building record. Wednesday's effort surpassed the old mark, a 67.2-percent performance, which came against Kentucky in 1991.
"We shot the ball well from all over the floor," LSU head coach John Brady said.
Five Tigers finished in double figures with Tony Gipson leading the way scoring 14 points. He connected on 4-of-4 shots from three-point range. Torris Bright managed 13 points while Collis Temple III and Antonio Hudson each pitched in a dozen. Ronald Dupree rounded out LSU leading scorers with 10.
The Tigers held a 28-17 lead with 9:19 to go in the first half before closing out the period with a 31-6 and maintained a 59-23 advantage (36 point) at the break.
"I consider Centenary a better team than they looked tonight," Brady said. "Our team played so well we made them look deficient."
The Tigers' 59, first half point total was the second highest ever scored by an LSU team. The Tigers scored 70 in the first half in a win over George Mason in 1994.
"There was a stretch in the first half where we defended, rebounded and passed the ball so well," Brady said.
LSU opened the second half scoring 14 consecutive points and led 73-23, a 40-point advantage, at the first media timeout coming at the 16:13 mark.
"When you are bigger, you get the ball closer to the basket and your shooting percentage is higher," Centenary head coach Kevin Johnson said. "They shot 70-percent because they were shooting over our 6-3 and 6-4 guys and they are used to playing against much bigger guys. I am sure that contributed to them shooting over 70-percent from the field and I do not think we were very sharp defensively."
Despite the fact LSU had a definite height advantage, the Tigers still managed to connect on 9-of-15 shots from three-point range, good enough for 60-percent shooting from beyond the arch.
Andrew Wisniewski paced Centenary with 25 points. Rickey Evans was the only other Gent in double figures with 16.
LSU outrebounded Centenary 39-16 and dished out 27 assists, compared to only 12 by the Gents.
It was the first time an LSU team eclipsed the century mark since scoring more than 100 points in a win over Wyoming in 1999.
The field goal percentage record was good enough to break the Maravich Assembly Center and LSU home number by surpassing Tulane's 68.4 mark, recorded in an NIT win over the Tigers in 1982.
The LSU record for field goal percentage remains in tact falling 1.1 percent shy of breaking the all-time record, a 71.4 shooting percentage in a win at Clemson in 1969. The top-two shooting performances in LSU history each featured a Maravich. The 1969 win over Clemson featured Pete Maravich. Wednesday, youngest son, Josh, saw action playing three minutes. He did not score in the contest.
With the win, LSU kept its streak of 43 wins over in-state opponents in tact having not lost a game to a Louisiana team since a 1988 loss to Louisiana Tech.
