Questions were raised about Ball's conditioning after his first workout for the Lakers, and the former UCLA star even acknowledged that the drills made him tired.
At an unspecified location in the Los Angeles area near his home, Ball did his normal on-court routine, ran hills and lifted weights, showing the team's brass how he conditions and getting some face-to-face time.
Ball's outspoken father, LaVar, who had not been invited to Lonzo's first workout at the Lakers' facility in El Segundo on June 7, was present for Friday's workout.
Magic Johnson, president of basketball operations, and general manager Rob Pelinka were the only representatives of the Lakers to attend Friday's workout, a source told ESPN's Ramona Shelburne. Coach Luke Walton remained in El Segundo for a draft workout with other players.
A source told Shelburne that Friday's workout with Ball was "solid."
LaVar Ball has been vocal about his desire for his son to play for the Lakers, and he previously has lobbied for the match.
"Team-wise, the Lakers are a better fit," he said after Lonzo's first workout. "They really don't have a leader. Boston already went to the playoffs. They have a leader."
Lonzo Ball has worked out only for the Lakers, but a source previously told Shelburne that, after Friday's workout, Ball will consider talking to other lottery teams that have asked to speak with him.
The Lakers, who have the No. 2 pick in Thursday's draft, had Kansas forward Josh Jackson in for a second look Tuesday. They also brought in Kentucky point guard De'Aaron Fox for a private workout Tuesday, after seeing him at the combine.
