The three-year pro appeared in all seven postseason games for Memphis and averaged 6.3 points and 2.4 rebounds across 20.9 minutes per game. His best game during the playoff came on May 29, when he finished with 17 points across 30 minutes off the bench against the Utah Jazz.2019

He also shot 46.6 percent from the field, 40.4 percent from three and 86.7 percent from the free-throw line.
