FAYETTEVILLE, Ark. -- One moment the Razorbacks were in the game, and the next it seemed like they were out of it.
Whitney Jones worked free for a layup, giving Arkansas a tie with No. 7 LSU with 10:35 remaining.
"I was so pleased at 49-49. I remember it vividly on the scoreboard," Lady Razorbacks coach Susie Gardner said. "Then you look up, like a blink of the eye later, and it's 10 points."
Then 15 points. Then 20.
Sylvia Fowles had 23 points and 20 rebounds, and LSU went on a 24-0 run in the second half for an 86-65 victory over Arkansas on Thursday night.
"Momentum changed just that quick," Lady Razorbacks' center Lauren Ervin said.
The Lady Tigers (23-4, 9-2 Southeastern Conference) led 32-28 at halftime, and Fowles scored their first eight points of the second half for a 40-30 lead. Arkansas twice rallied to tie it, the last time at 49-49.
LSU then scored 24 straight points before Brittney Vaughn made two free throws for Arkansas with 5:10 to play.
Mesha Williams began the run with a layup, and Quianna Chaney scored three straight baskets for an eight-point lead. Although the 6-foot-6 Fowles can be dominant in the half-court offense, the Lady Tigers looked to run. Erica White, their 5-foot-3 point guard, contributed four assists during the stretch.
"I thought we came out and established ourselves defensively a little bit better, which allowed us to get out in transition," LSU coach Pokey Chatman said. "You saw more hustle plays and people knocking down shots."
Fowles made her presence felt with a pair of three-point plays during the run, then saved an offensive rebound to Allison Hightower while falling out of bounds. Hightower's layup made it 71-49.
"They have so many weapons, and they were all firing tonight," Gardner said. "It was hard to stop them. You can call a 30-second timeout, but that doesn't always halt the efforts."
Fowles is one of only four players with a 20-point, 20-rebound game at LSU. She's done it three times. This was her 14th straight double-double and 55th of her career.
"Sylvia's going to get her numbers when we run good offense and we keep the floor spaced," Chatman said.
LSU has won 10 straight over Arkansas (18-9, 3-8).
The Lady Tigers had their 43-game home winning streak ended by a 72-71 loss to No. 5 Connecticut last weekend. Arkansas, which was nationally ranked earlier this season, has now lost six straight.
LSU shot 46 percent from the field, and Fowles was an uncharacteristic 8-of-18. She entered shooting 61 percent on the season.
Fowles had plenty of help against Arkansas. Chaney scored 21 points on 10-of-15 shooting, and White had 15 points, eight rebounds and seven assists.
"It was just me trying to get down the floor and see all my teammates," White said of LSU's decisive run. "Q-Chaney and Mesha did a great job of running the floor."
Donica Cosby scored 15 points for Arkansas, but finished 5-of-16 from the field. Sarah Pfeifer had 10 points and seven rebounds.
Ervin added 11 points and nine rebounds against Fowles in the low post.
"I like going up against her because it tests me as a person," Fowles said.
Fowles and LSU easily passed that test, no matter what the score looked like midway through the second half. The Lady Tigers could only be slowed for so long.
"I feel great about 30 minutes," Gardner said. "But those 10 minutes are almost a blur."
