The Crimson Tide (13-18, 7-11 Southeastern Conference) capped a disappointing regular season by dominating from start to finish a team that appeared to be playing its way into the NCAA tournament. Arkansas (21-10, 10-8) was held to a season-low in points three days after pouring in 110 to rout Mississippi.
Alabama hit 29 of 53 shots (54.7 percent) while holding Arkansas to 15 of 48 (31.3 percent). The Tide also out-rebounded Arkansas 41-25 in the surprisingly one-sided game.
Bama's only scholarship senior, Releford hit a late 3-pointer to move past Jerry Harper into fifth on the Tide's career scoring list with 1,862 points.
The Tide earned a bye into Thursday in the SEC tournament with the victory.
It was a potentially costly stumble in the postseason hopes of Arkansas, which hadn't trailed by more than 20 points all season. The Razorbacks' previous scoring low was 65 points in a win over Alabama month earlier.
The Tide improved to 7-2 in SEC games at Coleman Coliseum, where the Razorbacks have dropped seven in a row. It was a season-high in points for Alabama in SEC games.
Arkansas' Anthlon Bell, who scored a career-high 23 against Ole Miss, was 0 for 5 and didn't score.
Michael Qualls scored three points, nine below his season average.
The Razorbacks went cold after exploding for a 30-point win over Mississippi.
Alabama took a 39-16 halftime lead over Arkansas, which headed into halftime shooting just 4 of 23 from the field (17.4 percent).
The Razorbacks' previous first-half scoring low was 24 in the February meeting with the Tide. This time they didn't make a basket over the last 5:43 of the half.
Arkansas couldn't come any closer than 19 after that.
