Sammy Zeglinski scored 17 points, including a big 3-pointer late in the game, to help No. 21 Virginia beat LSU 57-52 in a non-conference game Monday night.

Joe Harris added 14 points, also hitting a 3-pointer late, for the Cavaliers (13-1), who have won 11 straight games.

With their lead down to one, Zeglinski made his fourth 3 of the game to put the Cavaliers on top 51-47 with 3:25 remaining. A 3-pointer by Anthony Hickey again reduced Virginia's lead to a single point before Harris made his 3-pointer with 1:30 left.

The Tigers cut their deficit in half at 54-52 on a field goal by Justin Hamilton with 51 seconds remaining. LSU got the ball back when Ralston Turner blocked a shot by Harris and Hamilton grabbed the ball. However, Hamilton immediately lost the ball.

The Tigers would have one more opportunity to tie the score after Zeglinski made just one of two foul shots with 19 seconds remaining, but Turner missed a 3 and Mike Scott hit two free throws with 5 seconds left to seal the win.

Hamilton had a career high 21 points for the Tigers (10-4), who had their winning streak end at seven games.

Despite holding the lead for most of the first half, Virginia needed a pair of free throws from Harris in the final 30 seconds to forge a tie going into the break. LSU had no more than a two-point advantage in the opening 20 minutes.

Baskets by Scott and Akil Mitchell enabled the Cavaliers to jump out front 13-6 in the opening eight minutes. The Tigers scored eight straight points on a pair of 3-pointers by Andre Stringer and a layup by Chris Bass to go ahead 14-13.

A field goal by Malcolm Brogdon and a 3-pointer by Zeglinski put Virginia ahead 18-14. LSU evened the score at 20-20 on a basket by Stringer with 4:59 remaining in the half. Harris scored Virginia's last six points, including the two foul shots, which tied the score at 26-26.

The Tigers grabbed a four-point lead at the outset of the second half on baskets by Hamilton and Turner. The Cavaliers responded with an 8-2 run to go ahead 34-32. A field goal by Harris gave Virginia its first lead of the second half.

LSU came back to take its largest advantage of the game at 42-37. Trailing by one point, Hamilton converted a three-point play and Jalen Courtney knocked down a 3-pointer. The lead was short-lived as the Cavaliers outscored the Tigers 9-2. A field goal by Scott gave Virginia a 46-44 lead with 6:20 to play.

LSU regained the lead at 47-46 on a 3-pointer by Hickey. A basket by Assane Sene with 5:13 remaining in the game gave the Cavaliers the lead for good at 48-47.
