Martin made the announcement in an ad that appeared in the Zanesville Times Recorder on Thursday, which read in part:
Thank you, thank you, thank you. There's not a more perfect day for me to express those feelings. There are so many ways to announce your after professional career plans. My family and close friends have known since June of the direction I wanted my life to go. Those were the toughest conversations that I have ever had but with the ultimate support I knew I was making the right decision.
Martin last appeared in an NBA game on May 12 in Game 6 of the Western Conference Semifinals as a member of the San Antonio Spurs. He grabbed two rebounds in just under six minutes.
The 33-year-old Martin played for five teams during his NBA career. The Sacramento Kings originally selected him 26th overall in 2004, and he spent five-and-a-half years with the franchise before it traded him to the Houston Rockets in 2010.
In three seasons with the Rockets, Martin had the most successful stretch of his career, averaging 21.3 points, 3.0 rebounds and 2.5 assists per game. Following his stint in Houston, he also spent time with the Oklahoma City Thunder and Minnesota Timberwolves before joining the Spurs in March.
Prior to debuting in the Association, Martin emerged as a dynamic talent during his college career at Western Carolina. During his junior season in 2003-04, he averaged 24.9 points per game and notched 44 against Georgia.
Martin never emerged as a superstar in the NBA, but he was a valuable role player who carved out a terrific career for more than a decade because of his ability to score. He's hanging up his basketball shoes without much fanfare but has a lot to look back on fondly.
