Patty Mills has declined his second-year option with the Spurs.

Mills will become a restricted free agent on Sunday.

Earlier this month, Mills told an Australian website he enjoyed his time with the Spurs and would be amenable to returning.

“I really enjoy being in San Antonio and being part of that program,” Mills told TheAge.com. “I definitely want (free agency) done soon … so that I can get it out of the way and go to London with a clear head.”
