LEXINGTON, Ky. -- Kyle Wiltjer's first 3-pointer gave him a feeling Friday would be a pretty good night.
His instincts were spot-on.
Wiltjer's shooting set the tone for an amazing offensive night for the Wildcats (2-1), who hit 40 of 62 attempts (65 percent), including 11 of 19 from behind the arc. He finished 7 of 11 on 3-pointers, including 5 of 8 in the second half.

"I tried to go hard in shootaround," Wiltjer said, "and coach (John Calipari) always said if you have a good shootaround you have a good game. I try to have that approach every game and come out confident, and tonight I was just fortunate to have some (shots) fall."
Wiltjer set the tone for a game that involved contributions from Kentucky's heralded freshmen class. Alex Poythress followed up his 20-point effort in Tuesday night's 75-68 loss to No. 9 Duke by hitting nine of 10 shots for a career-high 22 points to go with five rebounds.
That didn't stop Calipari from getting on Poythress' case, but it had the desired effect.
"He just expects more out of me," Poythress said. "He's just trying to pull it out. I don't blame him."
Nerlens Noel added 15 points and seven rebounds, Willie Cauley-Stein 14 and Archie Goodwin 13. Graduate transfer Julius Mays had 10 of the Wildcats' season-best 23 assists.
"We passed the ball to each other, shot a pretty high percentage from both the 3 and (the field)," Calipari said. "We're not a 57-, 58-percent 3-point shooting team but I believe we're a 40 (percent team)."
The Wildcats (2-1) won their fourth home opener under Calipari and 10th in the past 11 seasons. They also improved to 9-1 against the Patriot League.
Tony Johnson scored 13 points for Lafayette (1-2), which lost leading scorer Dan Trist to a sprained ankle during the morning shootaround.
The win opened a three-game homestand for Kentucky, which was coming off a fairly solid effort against Duke. The Wildcats shot 49 percent in that game, including 4 of 10 from 3-point range, and were nearly even on rebounds (31-30) against a veteran Blue Devils squad.
And the confidence gained from cutting a 14-point deficit to three before losing carried over against Lafayette, which was playing its first ranked opponent since an 86-41 loss to No. 6 Villanova on Nov. 20, 2010.
The Wildcats came out hot, hitting their first five shots and six of seven overall. Wiltjer started it with consecutive 3-pointers, Mays added one of his own and Kentucky was on its way to its best first half this season.
"The sky's the limit," Noel said of his teammates' play. "They can play real hard. It's not going to be long before things are clicking."
The Wildcats ended up hitting their first five 3-point attempts and six of eight to highlight a 20-of-31 shooting (65 percent) effort in the first half. Their previous best was 58 percent in the opener against Maryland.
More pleasing to Calipari was how well his seven-man rotation spread the ball around. Everybody scored, with Poythress muscling inside for 12 points, Noel adding nine and Cauley-Stein and Wiltjer eight each.
Despite starting without their best scorer, the Leopards were unfazed by height and talent disadvantages and stayed close -- albeit briefly. Levi Giese and Joey Ptasinski both sank 3-pointers, Alan Flannigan got an inside basket and Tony Johnson another off a Noel goaltending call.
That made it 15-10 but it was all Kentucky after that. A 7-2 spurt was followed by 15 unanswered points over a 3:34 span made for a 37-12 lead. Lafayette rarely got closer than 20.
With their tallest player being 6-foot-10 Ben Freeland, there was little the Leopards were going to do against the Wildcats' inside duo of 6-10 Noel and 7-foot Cauley-Stein to begin with. And other than a couple of sloppy stretches by Kentucky, Lafayette struggled to keep up athletically.
Losing the 6-9 Trist made things even tougher. He scored a career-high 30 points to lead Lafayette's 98-94 overtime win over LIU-Brooklyn on Monday and was expected to counter some of Kentucky's scoring.
"You need a post presence, you need someone you can throw it into," Lafayette coach Fran O'Hanlon said. "Dan Trist has been scoring the ball very well for us. I'm not sure he's going to be getting 20 points against Kentucky, but he gives us an inside presence, and then he makes our outside a little bit better.
"We are a much better team with Dan Trist. We're not Kentucky good, but we are much better."
His presence might not have helped the Leopards, who shot just 40 percent and committed 28 turnovers.
The Wildcats outscored the Leopards 50-18 in the second half.
