J.J. Sullinger made a three-pointer to put Arkansas back in front and a trey by Jannero Pargo with 3:12 to go gave the Razorbacks (10-5, 2-1) a 65-64 lead, but two free throws by Collis Temple and a three by Antonio Hudson gave the Tigers a 70-65 lead with 1:06 left.
Following Pargo's three, Brandon Dean, who had a terrific game in his home state of Louisiana, fouled out with 2:44 to go. When Dean left the game, LSU went on an 8-2 run to put the game away when Temple's jumper gave the Tigers a 72-67 advantage with only 43 seconds left.
Other than Dean and Teddy Gipson, Arkansas' other Louisiana native, Arkansas struggled from the field. Until Sullinger's three, which gave UA a 59-57 lead and its first points in 8:59 at the 6:23 mark, Dean and Gipson had scored all 16 of Arkansas' second-half points.
A Dean layup and a three by Gipson gave the Hogs a 45-33 lead. Gipson's trey with 15:22 left gave the Razorbacks their 13-point advantage.
Dean hit eight of 13 shots, including five of nine three-pointers, and had game highs of 24 points and five assists. Gipson was seven of 10, including three of three on treys, for a season-high 17 points to go with a season-high matching six rebounds.
The rest of team was a combined nine of 35 from the field.
Arkansas won the battle of the boards, outrebounding LSU, 34-27, but the Razorbacks had more turnovers than their opponent (16-12) for just the third time this year as the Hogs had their nine-game streak of forcing 20 or more turnovers snapped. LSU, which outscored Arkansas 31-8 at the free throw line, had just three turnovers in the second half.
Temple and Ronald Dupree led the Tigers with 21 points each while Antonio Hudson added 11 and Torris Bright 10.
Pargo had eight points for Arkansas. Dionisio Gomez had five points and seven rebounds, all on the offensive end.
