— 76ers forward Jerami Grant,who had a monster dunk over Ivica Zubac in Saturday’s loss to the Los Angeles Lakers, is going head-to-head with his brother, Bulls guard Jerian Grant, at the Thomas & Mack Center. Jerami is outscoring his brother, 8-5, but Chicago leads Philadelphia, 53-47, late in the third quarter.

6:24 p.m.

— Rashad Vaughn had a historically poor rookie year for the Bucks. Things didn’t get much better for the former UNLV and Findlay Prep star in Milwaukee’s Summer League opener in Las Vegas on Friday as he made only 4 of 16 shots from the floor and 1 of 8 from 3-point range.

Vaughn finally found his groove on Sunday afternoon, pouring in a game-high 24 points while making 10 of 18 shots and 3 of 6 3s in the Bucks’ 91-86 loss to the NBA D-League Select team at the Thomas & Mack Center.

“It felt good just to see it go in after (Friday),” Vaughn said. “I had to keep my confidence. I talked to some of my teammates and they helped me out.”

Bucks guard Michael Carter-Williams, the 2014 NBA Rookie of the Year, was at the game and said Vaughn just needs to stay confident.

“Especially when he misses a few, he’s a good enough shooter that he can make the next one,” he said. “He did a great job with that (Sunday). He really led the team. He’s really offensively talented. He just needs to keep putting his mind to it.”

The 17th pick in the 2015 NBA draft and the second-youngest player chosen, the 19-year-old Vaughn shot 30.5 percent from the field and 29.3 percent from 3-point range, averaging 3.1 points and 14.3 minutes in 70 games.

According to Bucks fan blog Brew Hoop, no rookie in NBA history has played at least 1,000 minutes while compiling a lower player efficiency rating than Vaughn’s mark of 4.2.

“I learned so much my rookie year, just getting stronger and understanding it’s a process. You’ve got to trust the process, stay patient and keep working hard,” Vaughn said. “I’ve been working real hard this summer. I’m very confident and will stay focused on getting better.

“ I’m just working on every aspect, shooting more consistent, finishing around the rim and getting stronger.”

Bucks 7-foot-1-inch rookie forward Thon Maker, the 10th overall pick in the 2016 NBA Draft, had 17 points and 17 rebounds in the losing effort.
