Matt Barnes announced his retirement from the NBA Monday on Instagram.
Barnes, 37, has played 15 years in the league, spending time with nine different teams during his career. Last season, he picked up his first career NBA title when he signed with the Warriors toward the end of the year after Kevin Durant went down with an injury.
Barnes started his career with the Clippers in 2004 after he was drafted by the Grizzlies in the second round of the 2003 draft and was immediately traded to the Cavaliers, who waived him before the start of the 2003-04 season.
