Projected No. 1 pick LaMelo Ball conducted an individual workout with the Minnesota Timberwolves, owners of the top selection in the upcoming NBA draft, on Wednesday in Southern California, sources told ESPN.

It was the first private workout Ball granted an NBA team. He previously met and interviewed with the Timberwolves, Golden State Warriors, Charlotte Hornets and Chicago Bulls, who hold picks 1-4, respectively.

The NBA relaxed restrictions on in-player evaluations and interviews in mid-October, according to a memo obtained by ESPN, opening the way for teams to meet with prospects in advance of next Wednesday's draft.

The Timberwolves sent president of basketball operations Gersson Rosas, coach Ryan Saunders and executive vice president of basketball operations Sachin Gupta to evaluate Ball, putting him through an array of shooting drills and other activities to test his ballhandling and conditioning. A source said Ball shot the ball well and had no issues getting through the workout.

Ball is one of three candidates the Timberwolves are expected to choose from on draft night. The others are former Memphis center James Wiseman and Georgia guard Anthony Edwards.

The Timberwolves previously met with and worked out Edwards but have not been able to get much traction with Wiseman. A source told ESPN that Wiseman appears to view situations with the Warriors and Hornets as more favorable to his long-term growth. Despite that, and the presence of All-Star center Karl-Anthony Towns, Wiseman remains a candidate for the Timberwolves.

The Timberwolves also are expected to conduct trade discussions with a number of teams interested in acquiring the top pick.
