Bucks coach Mike Budenholzer said before the game that most of them had a good scrimmage on Sunday so he didn't want to play them in what was essentially a back-to-back stretch.
Williamson, the No. 1 overall pick in June's draft, threw down his first preseason dunk, a tomahawk over 7-foot center Damian Jones less than two minutes into the game and finished with seven rebounds, three assists and three steals.
Brandon Ingram scored 19 points, Lonzo Ball had nine points and seven assists and Nikeil Alexander-Walker added 12 points for the Pelicans. Ball blocked a shot, grabbed the rebound and led the break before feeding Williamson for a monster two-handed jam in the first quarter.
MAGIC 115, PISTONS 91
Mo Bamba scored 13 points and Nikola Vucevic had 10 points and 10 rebounds for the Magic. Markelle Fultz added eight points, four rebounds and seven assists. The No. 1 overall pick by Philadelphia in the 2017 draft, Fultz was acquired by Orlando in a trade for Jonathan Simmons, a second-round pick in the 2019 draft and a protected first-round pick in the 2020 draft.
KNICKS 104, WIZARDS 99
Morris was ejected early in the third quarter for purposely hitting Washington's Justin Anderson on the head with the ball.
Moritz Wagner, acquired from Los Angeles in a three-team trade that sent Anthony Davis from New Orleans to the Lakers, led the Wizards with 16 points. Rui Hachimura, the No. 9 overall pick in June's draft, scored 12. Bradley Beal finished with five points on 2-of-10 shooting in 16 minutes.
Kevin Knox and Wayne Ellington added 12 points apiece for the Knicks and Julius Randle had 11 points, seven rebounds and seven assists. The 24-year-old Randle, who was the No. 7 overall pick in the 2014 draft, signed a 3-year, $63 million contract with New York in July.
CAVALIERS 120, SAN LORENZO 89
At Cleveland, rookie Darius Garland sparked the Cavaliers in a win over San Lorenzo de Almagro of Argentina in Cleveland coach John Beilein's exhibition debut.
The No. 5 overall pick in this year's draft, Garland came off the bench and scored nine points, including five in a strong second quarter as the Cavs outscored Argentina's reigning league champions 43-29 to take an 11-point halftime lead.
Garland, who had been slowed in training camp by a foot injury, dropped a 3-pointer on his first shot in an NBA game and added two assists in the quarter, when Cleveland made 17 of 23 shots.
Cavs rookie Kevin Porter Jr., another first-round pick, scored 16 in 14 minutes. Jordan Clarkson scored 17 and Tristan Thompson added 14 and 10 rebounds.
Esteban Batista scored 20 and Darquavis Tucker 17 for San Lorenzo.
