DURHAM, N.C. (AP) Mike Krzyzewski inched closer to the latest milestone of his Hall of Fame career by beating the program that helped shape him into Coach K.
Tyus Jones had 16 points and a season-high 10 assists, and No. 4 Duke beat Army 93-73 on Sunday to bring Krzyzewski within 10 wins of 1,000 for his career.
''I love West Point. I love the fact that I had that opportunity (to attend) and then I had an opportunity to coach there,'' Krzyzewski said, his eyes welling with tears. ''And one of the reasons I'm a good coach here is my five years there. ... They'll always be in my heart, and I'll always be a West Pointer.''
Fellow freshman Jahlil Okafor added 21 points while Quinn Cook and Rasheed Sulaimon had 13 apiece for the Blue Devils (7-0).
They shot 52 percent, built a 43-25 rebounding advantage and overcame a season-worst 4-of-19 performance from 3-point range.
Duke tuned up for Wednesday night's visit to No. 2 Wisconsin by helping Krzyzewski defeat his alma mater and earn career victory No. 990.
''We knew this was a big game for coach, and a big game for us,'' Okafor said.
Kyle Wilson and Tanner Plomb each scored 19 points for Army (5-1).
The Black Knights gave Duke's transition defense headaches all day before their best start in 38 years was spoiled by their former team captain and head coach.
''I thought our guys ... stayed in the center of the ring,'' coach Zach Spiker said.
This was the sixth meeting between a Krzyzewski-coached Duke team and Army, so naturally the dominant subplot was Coach K - who starred for Bob Knight at Army in the 1960s and coached the Black Knights for five years before coming to Duke in 1980.
The twist in the latest matchup was that the last coach to lead Army to a 5-0 start was Krzyzewski - whose 1976-77 team won its first seven.
That footnote still belongs to him. For much of the day, keeping it wasn't easy.
Army pulled within single digits with just under 18 minutes left when Dylan Cox's three-point play made it 44-35.
Amile Jefferson followed by banking in a jumper through contact, and when he missed the free throw, Okafor got the rebound and laid it in. Jefferson hit one free throw on Duke's next possession and after his miss, the Blue Devils forced a held ball to set up the play of the game: Okafor's two-handed dunk off Jones' inbounds pass that pushed the lead to 51-35 - Duke's largest to that point - with 16:52 left.
Duke has trailed at home twice all season. In both instances, the only scholarship senior on the roster put the Blue Devils back on top. Army led this one for a little over 2 early minutes before Cook's driving layup put Duke up 7-5.
