MINNEAPOLIS (AP) — The Minnesota Timberwolves have signed rookie center Naz Reid to a multiyear contract, upgrading the two-way deal they initially gave him before a strong performance for the team’s entry in the NBA Summer League in Las Vegas.

The new contract, completed Thursday, all but ensures that Reid will be on the regular-season roster, after going undrafted out of LSU.

The 6-foot-10, 250-pound Reid averaged 11.9 points and 5.4 rebounds in 18.6 minutes over seven summer league games against other clubs largely composed of rookies and second-year players. The Timberwolves’ team reached the championship game.

Reid averaged 13.6 points and a team-high 7.2 rebounds in his lone season at LSU, which reached the Sweet 16 of the NCAA Tournament.
