Martin officially signed with the Spurs on Wednesday, Shams Charania of Yahoo! Sports reports.

Analysis:

Martin had reached an agreement to join the Spurs several days earlier, but the team needed to open up a roster spot for him before he was eligible to play. The team did just that Wednesday, waiving veteran swingman Rasual Butler. It's unclear if Martin will be available for Thursday's game against the Bulls after having limited practicing time with his new team, but it shouldn't be long before he finds a role in the rotation as a designated sharpshooter off the bench. Since the Timberwolves waived Martin before March 1, he'll be eligible for the postseason with his new squad.
