Grizzlies Sign Zyon Pullin, Waive Colin Castleton

1:50pm: The moves are now official, the Grizzlies confirmed in a press release (Twitter link).


1:25pm: The Grizzlies are signing free agent guard Zyon Pullin to a two-way deal covering two seasons, reports Drew Hill of The Daily Memphian (Twitter links).

According to Hill, Memphis will waive center Colin Castleton in order to add Pullin to the roster.

A 6’4″ guard out of Florida, Pullin played for UC Riverside from 2019-23 before transferring to the Gators for his super-senior year. He was an All-SEC honoree in 2023/24 after averaging 15.5 points, 4.9 assists, 3.9 rebounds, and 0.9 steals per contest in 33 games (27 starts), with a shooting line of .444/.449/.847.

Pullin quickly agreed to terms with the Heat after going undrafted in June, officially signing a two-way contract with the team on the first day of the new league year on July 1. However, he didn’t see much playing time for Miami’s Summer League squad and was waived on July 25 when the club needed to open up a roster spot to sign Summer League standout Josh Christopher to a two-way deal.

Pullin re-signed with the Heat on an Exhibit 10 deal in August, then was released shortly before the ’24/25 season began. He has spent his first pro season playing for Miami’s G League affiliate, the Sioux Falls Skyforce.

The 23-year-old had a relatively modest role with the Skyforce during the Tip-Off Tournament this past fall, averaging 9.0 PPG, 4.1 RPG, 2.8 APG, and 0.8 SPG on .476/.318/.765 shooting in 17 games (22.4 MPG). However, he has received more playing time (38.3 MPG) in his first six regular season games with Sioux Falls, and he has excelled in those outings, averaging 24.8 PPG, 7.3 RPG, 7.7 APG, and 1.2 SPG on .535/.424/.731 shooting.

Castleton, who spent ’23/24 with the Lakers on a two-way deal, hasn’t played much for the Grizzlies during his second season, playing just 46 NBA minutes in 10 games. The 24-year-old big man put up 17.5 PPG, 9.0 RPG, 3.2 APG, and 1.3 BPG in 10 outings with the Memphis Hustle (31.8 MPG), though he struggled with turnovers (3.8 per game) and scoring efficiency (.438/.261/.756 shooting line).

Castleton recently had his full-season salary guaranteed by the Grizzlies, but two-way contracts don’t count against the salary cap, so Memphis won’t face any tangible financial ramifications for making the roster swap.
