LEXINGTON, Ky. — No. 5 Kentucky got the strong start it sought against No. 1 Tennessee and for a moment was blowing out the Volunteers.
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 upset Tennessee, 86-69, Saturday night to end the Volunteers’ 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 Volunteers’ 13-0 spurt soon after that cut the advantage in half. Kentucky maintained a double-digit lead to win the highly anticipated matchup of top-five schools.
Kentucky (21-4, 10-2) also avoided a second consecutive Southeastern Conference loss to stay within reach of co-leader Tennessee (23-2, 11-1), which hadn’t lost since Nov. 23 to No. 2 Kansas.
‘‘It shows everybody that we can still play with great teams in this league and also in the country,’’ said Washington, who scored Kentucky’s first 7 points and finished 9 of 12 from the field for his seventh 20-point effort in the past eight games.
Johnson, meanwhile, made 8 of 14 with three 3-pointers as the Wildcats shot 55 percent. Tyler Herro had 15 points and 13 rebounds as Kentucky beat Tennessee, 39-26, on the glass.
It was a big improvement from Tuesday night’s 73-71 home loss to No. 19 LSU, a game decided on a last-second tip-in the Wildcats thought was basket interference. However, Kentucky played a big role with breakdowns and questionable shots that let the Tigers rally and eventually win the game.
The Wildcats rebounded with an effort that was thorough in many phases.
They outscored the Vols, 36-20, in the paint and edged them, 17-14, in second-chance points. And instead of letting Tennessee expand its one encouraging run, Kentucky did what it had to do to keep a double-digit advantage.
‘‘I hit them right after the game with LSU and said, ‘Hey, that was a tough loss,’’’ Kentucky coach John Calipari said. ‘‘But you know, we needed it. We need to go back to what we were, and sometimes you’ve got to get knocked in the head to know that.
‘‘So the loss to LSU probably helped us win this game.’’
Other than managing to enter the break trailing, 37-31, and that second-half run, Tennessee wasn’t a factor.
Jordan Bone had 19 points and Admiral Schofield 17 for the Volunteers, who scored the game’s first basket but trailed afterward. Tennessee shot 35 percent in the second half and 41 percent overall.
‘‘Tonight, we weren’t Tennessee tough,’’ Schofield said. ‘‘Kentucky was totally kicking our butt, scoring the ball, defense, everything.’’
