Holmgren shot 7 of 10 in a game that was originally expected to be a matchup of the Nos. 1 and 2 picks. But the Magic announced earlier Monday that Paolo Banchero would not play the remainder of the summer after averaging 20 points, five rebounds and six assists in his two games in Las Vegas.

After Lindell Wigginton made two free throws to give the Bucks a one-point lead, Ryan took the inbounds pass, dribbled up the left sideline and went behind-the-back near midcourt and hit a straight-away 3 with the 6-foot-7 MarJon Beauchamp in his face. Ryan appeared to hurt his left ankle on the play and writhed in pain on the court before Wigginton missed a heave from beyond half court as time expired.
