INDIANAPOLIS (AP) - RJ Barrett scored 33 points and Zion Williamson added 28 in their first college games, leading No. 4 Duke over No. 2 Kentucky 118-84 on Tuesday night in the season-opening Champions Classic.
It was the most lopsided defeat in coach John Calipari's tenure at Kentucky and marked the eighth time in 10 meetings the Blue Devils have beaten the Wildcats.
Both Barrett and Williamson surpassed Marvin Bagley III's program record for points by a freshman in his debut at 25. Cam Reddish added 22 points and Tre Jones had six, giving Duke's freshmen a combined 89 points.
The teams set a Classic record for most combined points, set hours earlier in No. 1 Kansas' 92-87 victory over No. 10 Michigan State.
Keldon Johnson scored 23 points to lead Kentucky. Graduate transfer Reid Travis added 22 for the Wildcats, who had won all nine previous season openers under Calipari.
• NO. 1 KANSAS 92, NO. 10 MICHIGAN STATE 87: Quentin Grimes scored 21 points in his college debut and Dedric Lawson added 20 points and 14 rebounds to lead No. 1 Kansas past No. 10 Michigan State in the Champions Classic.
The Jayhawks won their third straight in one of college basketball's premier events.
Michigan State was led by Joshua Langford with 18 points and Kenny Goins with 17 points and 11 rebounds. The Spartans are now 4-21 all-time against No. 1 teams.
The game pitted two power-conference preseason favorites against each other, and the finish was every bit as intriguing as expected.
After Kansas was in control for most of the game, the Spartans frantically trimmed a 10-point deficit to 90-87 with 34 seconds left. They had a chance to make it a two-point game when Devon Dotson missed the second of two free throws with 15 seconds left.
But Cassius Winston missed a layup for Michigan State, Kansas grabbed the rebound and Grimes sealed it by making 1 of 2 free throws.
• NO. 3 GONZAGA 120, IDAHO STATE 79: Rui Hachimura scored 33 points to help No. 3 Gonzaga beat Idaho State.
Zach Norvell Jr. added 23 points for Gonzaga, which has the highest preseason ranking in school history.
• NO. 5 VIRGINIA 73, TOWSON 42: Ty Jerome scored 20 points and De'Andre Hunter had 13 and 10 rebounds as No. 5 Virginia beat Towson.
Jerome made six 3-pointers for the Cavaliers, who were playing for the first time since they made history by becoming the first No. 1 seed to lose to a 16-seed in the NCAA Tournament. That 74-54 loss to UMBC last March, they insisted leading into the opener, was the furthest thing from their mind.
• NO. 6 TENNESSEE 86, LENOIR-RHYNE 41: Jordan Bone scored 18 points, Kyle Alexander added 16 and No. 6 Tennessee opened the season with a blowout over Lenoir-Rhyne.
Tennessee coach Rick Barnes lettered for three seasons at Lenoir-Rhyne. Barnes is a native of Hickory, North Carolina, where Lenoir-Rhyne is located.
• No. 7 NEVADA 86, BRIGHAM YOUNG 70: In Reno, Caleb Martin scored all 21 of his points in the second half and Jordan Caroline tied a career high with 16 rebounds to help Nevada beat Brigham Young.
After Nevada's offense sputtered in the first half, it accelerated in the second, especially in the game's final 10 minutes. Nevada shot 27 percent from the field in the first half and 51 percent in the second.
• NO. 8 NORTH CAROLINA 78, WOFFORD 67: Luke Maye had 24 points, Cameron Johnson provided a huge spark in the second half and No. 8 North Carolina avenged an upset loss to Wofford last year.
Johnson made five 3-pointers and had 17 points along with eight rebounds. Garrison Brooks added 20 points as the Tar Heels improved to 15-1 in season openers under coach Roy Williams.
• NO. 9 VILLANOVA 100, MORGAN STATE 77: Eric Paschall scored 26 points, Phil Booth had 17 and No. 9 Villanova opened its national championship defense with a win.
The Wildcats have won 12 straight games dating to last season and won their 16th consecutive season opener.
• NO. 19 MICHIGAN 63, NORFOLK STATE 44: Jon Teske had 13 points, eight rebounds and four blocks as No. 19 Michigan gave John Beilein his 800th career coaching victory.
Before the game, the Wolverines raised Final Four and Big Ten championship banners earned by last season's team.
Michigan's Charles Matthews scored 10 points but was 0 of 4 on 3-pointers and 0 of 5 on free throws. Freshman forward Ignas Brazdeikis had 12 points on 3-of-10 shooting in his debut with the Wolverines.
• NO. 24 PURDUE 90, FAIRFILED 57: Carsen Edwards scored 30 points and made seven 3-pointers as No. 24 Purdue opened its season with a victory over Fairfield.
Purdue made just one of its first seven shots but shot 54 percent. More impressively, the Boilermakers made 14 of 30 from 3-point range and hit eight 3-pointers in the first half.
The Boilermakers went on separate 14-0 and 7-0 runs in the first half and built a comfortable 17-point halftime edge. They consistently shut down Fairfield on defense and coasted to their first victory of the year.
