The 17th overall pick in the 2018 NBA Draft after three years at Villanova, DiVincenzo appeared in 27 games with the Bucks, seeing 15.2 minutes per contest. He averaged 4.9 points, 2.4 rebounds and 1.1 assists while shooting 40.3 percent from the field, 26.5 percent from three and 75.0 percent from the free-throw line. He may have had opportunities to appear in more games, though he dealt with a heel injury for a significant chunk of the season. Arguably his best performance of the season occurred during a 22-point victory over the Magic. DiVincenzo posted a career-high 15 points (6-9 FG, 1-4 3Pt, 2-2 FT) and three rebounds in only 18 minutes. His other career highs were, respectively, eight rebounds, five assists, three steals and two blocks. DiVincenzo was part of a very successful five-man lineup that was plus-35.5 points per 100 possessions in a 21-minute sample, and it included Eric Bledsoe, Khris Middleton, Ersan Ilyasova and John Henson. The Bucks' home court seemed to make DiVincenzo more comfortable, as he posted a better true-shooting percentage (54.8) and net rating (plus-3) than he did on the road. In the six games that DiVincenzo saw at least 20 minutes, he averaged 8.0 points and 3.5 rebounds while totaling a combined seven steals-plus-blocks. His most efficient month was March, when he shot 8-of-17 from the field and 5-of-14 from distance for an effective field-goal percentage of 61.8.
