Steven Pledger scored 19 of his 22 points in the second half as Oklahoma downed visiting Arkansas 78-63 Saturday.

Andrew Fitzgerald scored all 17 of his points in the first half and Tyler Neal added a career-high 16 for the Sooners (7-1), who have won 32 straight non-conference home games and 90 of their last 92 at Lloyd Noble Center.

The home team has won each of the last five meetings between the schools.

Arkansas (5-3) opened the game with four straight points, but Oklahoma rolled off 12 straight and 22 of the next 25 points as Fitzgerald dominated the first half by hitting his first seven shots.

The Razorbacks worked the deficit into single digits with full-court pressure early in the second half, and Fitzgerald picked up his fourth foul with 14:20 remaining. But Pledger picked up the scoring slack from that point on, helping the Sooners expand their advantage to as many as 18 points late.

Freshman guard B.J. Young followed up his career-best 28-point effort against Connecticut last Saturday with 24 more for Arkansas, which shot just 34 percent and went just 7 of 27 from the 3-point line.
