Arkansas picked the right time to start draining 3-pointers.
Ricky Scott scored 18 points and the Razorbacks equaled their Southeastern Conference-best with nine 3s in pulling away to an 82-74 victory over No. 25 Vanderbilt on Tuesday night.
Five players scored in double figures for the Razorbacks (16-6, 4-3), who improved to 16-0 in Bud Walton Arena this season. Julysses Nobles added 17 points for Arkansas.
The Commodores (16-6, 5-2) led 40-37 in the second half before Arkansas' Hunter Mickelson tied the game with a 3-pointer.
That started a stretch where the Razorbacks hit six of seven field goals from behind the arc and took a 59-46 lead.
Vanderbilt, which was led by John Jenkins' 19 points, was unable to get closer than seven points after that.
Jeffery Taylor added 18 points for the Commodores, while Festus Ezeli had 14 and Steve Tchiengang 10.
Arkansas equaled the best start to open a season since the 1993-94 national championship team had the same home mark for the entire season. Only that team and the 1997-98 team have gone undefeated at home since the arena opened in 1993.
The Razorbacks entered Tuesday night with home wins over two ranked teams already this season: then-No. 15 Mississippi State and then-No. 20 Michigan. They used big first-half runs in both of those wins, but didn't follow that script in falling behind 34-32 at halftime to the Commodores.
This time, Arkansas pulled away in the second half with its 3-point barrage against a Vanderbilt team that had won 11 of 12.
B.J. Young finished with 12 points for the Razorbacks, while Mardracus Wade and Ky Madden added 10 apiece.
Mickelson, who was 4 of 4 from the field and had an impressive spinning dunk past Ezeli in the second half before fouling out, finished with nine points. The freshman started the 3-point party to tie the game at 40-40, and Wade and Scott each hit two during the run of six 3-pointers in seven attempts.
Young drained the final 3-pointer during the run to put the Razorbacks up 57-56. He then added two free throws to stretch the lead to 59-46, leaving the Commodores stunned and sending them to 4-2 on the road this season.
Arkansas built a 25-18 lead on the back of Nobles, who had 11 points and was 3 of 4 on 3-pointers in the first half. The Razorbacks benefited from their pressure defense, which forced Vanderbilt into six early turnovers.
Ezeli made sure the lead was short-lived, leading the Commodores on an 11-0 run that put them up 29-25. Ezeli, who had 21 points in his last game against Middle Tennessee, scored nine straight to ignite the run -- twice scoring while he was fouled and putting back another miss while having his way with Arkansas' interior defense.
Vanderbilt was 13 of 25 (52 percent) in the first half, during which the Razorbacks were forced to use a smaller lineup for much of the time due to early foul trouble.
Arkansas closed out the half with a lineup that featured 6-foot-4 Brandon Mitchell as its tallest player on the court and he was guarding the 6-11 Ezeli.
Arkansas 82, Vanderbilt 74
