Kendrick Nunn scored a career-high 28 points to add to his record-setting start and Miami beat Atlanta 106-97 on Thursday night, giving the Heat two wins over the Hawks in three days.

Nunn’s 112 points are the highest total through the first five games for any undrafted player in NBA history. Connie Hawkins of the Phoenix Suns scored 105 points in his first five games of the 1969-70 season.

Nunn, a 6-foot-2 guard from Oakland University in Michigan who transferred from Illinois, scored 14 points in the third quarter. He began his career with 24 points against Memphis on Oct. 23, and he has kept shooting. He has scored at least 24 points three times in Miami’s first five games.

Another record-setting rookie, Tyler Herro, had 17 points. Herro scored 29 points off the bench in the Heat’s 112-97 win over Atlanta on Tuesday night to set a franchise record for a rookie reserve.

The rookies have helped Miami (4-1) enjoy a strong start.

Nunn and Herro are feeding off Jimmy Butler, who had 11 assists while scoring only five points. He added nine rebounds, six steals and blocked three shots.

The Heat had 29 assists with only 13 turnovers.

Former Chicago prep star Jabari Parker led Atlanta with 23 points. DeAndre Bembry had 18 points, 10 rebounds and eight assists.
