LEXINGTON, Ky. — No. 5 Kentucky got the strong start it sought against No. 1 Tennessee and for a moment was blowing out the Vols. Most important was that the Wildcats finished off the Vols on a national stage, just what they needed days after letting one slip away. PJ Washington scored 23 points, Keldon Johnson added 19 and Kentucky beat Tennessee 86-69 Saturday night to end the Vols’ school-record, 19-game winning streak. The Wildcats used a 25-7 surge over a little more than seven minutes for a 62-38 lead, providing a cushion that withstood the Vols’ 13-0 spurt soon after that cut the advantage in half.
