In the final two months of the 2016-17 season, Phoenix Suns big man Alan Williams averaged 10.9 points, 8.7 rebounds in 21.5 minutes per game. Those rapid signs of growth helped make him an under-the-radar target in free agency this summer, but he won’t be leaving Phoenix for a while.

According to Shams Charania of The Vertical, Williams and the Suns agreed on a three-year deal last night. Here’s more from Charania on the reported deal:

Restricted free-agent center Alan Williams has agreed to a three-year, $17 million contract to re-sign with the Phoenix Suns, league sources told The Vertical.

Williams, an active rebounder and finisher, averaged 7.4 points and 6.2 rebounds in 15.1 minutes per game last season for the Suns.

After going undrafted out of UC Santa Barbara in 2015, Williams starred in the NBA summer league and signed a lucrative deal in the Chinese Basketball Association. He signed with the Suns on a two-year contract in March 2016 after returning from China and elevated his role as a reserve center last season.

Williams, 24, is a native of Phoenix, where he attended high school.
