Marcus Thornton had a game-high 28 points and Tasmin Mitchell 20 as SEC front-runner and No. 23 LSU rallied from 18 points down to beat Arkansas 72-69 Wednesday night before 13,549 fans at Bud Walton Arena.
That included Mitchell hitting a go-ahead bucket with 1:41 remaining and then Thornton capping the scoring with two free throws with 11 seconds remaining.
"We wanted the win and they wanted the win, but hats off to my team for taking the big win," Thornton said. "It was a tough one, even though we were the ranked team."
Rotnei Clarke and Courtney Fortson had 17 points each and Jason Henry and Michael Washington 10 as Razorbacks (13-11, 1-10) lost while freshmen were scoring 53 of their 69 points.
"We had opportunties to win that game, no matter what the time was," Clarke said. "We had a lot of energy on both sides of the floor. We were flying around showing some passion."
Clarke - 6-of-8 from the field and 4-of-6 from 3-point range - had an off-balanched shot near the buzzer to tie it, but came up empty.
"It wasn't really executed," Clarke said. "We were going to come down looking for something. He made both of his free throws so we knew we had to make it a tie game."
Arkansas head coach John Pelphrey coached despite a case of bronchitis, but his assistants handled all the postgame duties in a pre-arranged format.
Tom Ostrom was designated to handle the media interview. He noted the Hogs led in rebounds in the first half, but were throttled on the board after intermission. LSU won the rebounding, 41-34, including 20-11 in the second half.
"It came down to rebounding," Ostrom said. "We get a couple more rebounds, we win. We gave up too many offensive rebounds.
"We gave up second shots. We would have a good defensive possession, stop the first shot, but not stop the second shot. You have to finish. You have to close out. The first shot didn't hurt us."
LSU coach Trent Johnson said, "We had great energy on three of the last five possessions and our reaction to the ball was very good. We don't quit ... I mean, we keep fighting through to the end of possessions. We execute and compete."
Asked about struggling to get past 1-10 Arkansas, Johnson noted the many freshmen in the home team's lineup.
"This league is supposed to be down, but that's what happens with youth," Johnson said. "This is a team (Arkansas) I don't want to play again. Those two guards, Fortson and Clarke, they are a handful."
Ostrom said Fortson -- coming of a 1-game suspension -- was "incredible. I'm not sure he made a basket in the first half and he had some early turnovers, but you wouldn't know it by his facial expression. He kept playing so hard." Chris Johnson had 12 points, 12 rebounds and 6 blocks LSU (22-4, 10-1) won in large part because they grabbed a whopping 20 offensive rebounds while winning the board battle 41-34.
Mitchell had 8 offensive caroms and Johnson 5 of those.
"We were really aggressive toward the end and crashed the boards," Mitchell said.
Clarke - 6 of 8 from the field overall and 4-of-6 from 3-point range missed a hurried 3 near the buzzer as the Razorbacks lost their fifth of sixth SEC home games this season.
It also gave LSU a sweep of the season series and was its seventh straight win overall, fifth on the road and 10th straight league win since opening with a loss at Alabama.
Washington had 8 rebounds and Fortson 7 for the Razorbacks, who committed 16 turnovers, shot 41.7 percent from the field, hit 6 of 8 3-pointers and 13-od-19 free throws.
"Of course it's tough to lose at home," Fortson said. "LSU is a great team. They came in here and wanted it and got the win. We got the shots we wanted. It just wasn't falling through."
The Tigers shot 53.1 percent in the second half to up their overall mark to 43.8 percent for the game, had 15 turnovers, hit just 4-of-16 3-pointers and just 12-of-24 attempts from the charity stripe.
"We expected them to be agressive and we got them out of sync," Mitchell said.
LSU, which trailed by 18 in the opening half and by 9 with under 8 minutes left in the contest, grabbed the lead 70-69 on Mitchell's jumper with 1:41 left in the game.
After that Johnson blocked a Fortson shot and Sanchez was stripped - both on shots that would have given the home team the lead.
The Razorbacks' only point after Sanchez' old-fashioned 3-point play with 5:05 left to put his team up 68-61 was Washington's free throw with 2:13 remaning.
Clarke scored 9 of his 12 first-half points in a stretch in which the Razorbacks went on a 17-3 run.
He sandwiched two 3-point bombs around an old-fashioned 3-point play - off a steal in the backcourt - to give his team a 26-9 lead with 7:53 remaining in the opening half.
"Every time I hit a couple of shots, I knew they were going to stick me a little bit more," Clarke said. "Fortson and the rest of the guys did a great job of finding me."
That lead grew to 28-10 when Andre Clark hit a turnaround on the baseline just over a minute later.
LSU then began its push and had it down to 32-26 by halftime when Thornton scored with 10 seconds left before intermission.
The Razorbacks had the lead at halftime despite Fortson, Washington and Welsh going a combined 1-for-16 in a game they were 10-of-33 at the conclusion.
The Tigers then took the lead 37-36 when Thornton hit a free throw off a Pelphrey technical with 16:12 left.
Arkansas actually came back to take a 9-point advantage twice - the final time on Fortson's acrobatic lay-up that pushed his team ahead 61-52 with 7:47 left.
LSU rallied by getting on the boards once again. The Tigers had three stick-back buckets after rebounding missed free throws.
"We definitely knew coming into the game they were going to be very athletic, very strong," Sanchez said. "We knew they would be crashing the boards hard."
The Razorbacks - whose only road win was at South Alabama in its non-conference slate - will try again for its first SEC road win at South Carolina Saturday night at 6 p.m.
