The Memphis Grizzlies have agreed to a three-year, guaranteed contract with free-agent guard Andrew Harrison, according to The Vertical's Adrian Wojnarowski.
The 44th pick in the 2015 draft, Harrison spent last season with the D-League's Iowa Energy, averaging 18.5 points, 4.9 assists, 4.3 rebounds, and 1.5 steals in 46 games.
Harrison joins Troy Daniels and Chandler Parsons as the Grizzlies' newest offseason additions.
The 21-year-old point guard will fight with 2016 draftee Wade Baldwin for backup point guard duties.
Andrew is the brother of Charlotte Hornets guard Aaron Harrison.
