The Grizzlies will exercise their 2018/19 team option on Jarell Martin‘s rookie contract in advance of Tuesday’s deadline, league sources tell Michael Scotto of Basketball Insiders (Twitter link). It’s a fourth-year option for the young power forward. It’s an impressive turn of events for Martin, who appeared on the verge of being waived earlier this month. Entering training camp, Memphis was carrying more than 15 players on guaranteed contracts, and Martin appeared to be the odd man out. However, the club gave him the opportunity to make an impression during the preseason and he did just that, earning a roster spot over youngsters Wade Baldwin and Rade Zagorac, who were both waived. In the early going this season, Martin has been the Grizzlies’ starting power forward, averaging a career-high 23.9 minutes per game. He’s contributing a modest 7.1 PPG and 4.6 RPG.
