The Oklahoma City Thunder star will be the most coveted free agent on the open market next summer and the Wizards, Durant's hometown team, expect to be in the running.
"There's gonna be an opportunity to throw a pitch at him to try to get him to come back home," Wall told Comcast SportsNet Mid-Atlantic.
Teams are prohibited from speaking to or about any future free agents, and at present the two stars can focus only on their current teams.
"But I know one thing of just knowing him he's going to be very focused on taking care of Oklahoma City this season, and I'm going to be focused on taking care of the Washington Wizards," Wall said. "But when the time is right and he can get away from all that, yeah, we'll probably have some conversation and throw a pitch."
And while Durant's recent appearance on the Washington Redskins' sideline for their Thursday night game against the New York Giants may have reignited the "KD2DC" movement, the former MVP has never wavered in professing his love of Oklahoma City.
"I love it here, man. I love my teammates, I love the city, I don't really think about anywhere else," Durant told Revolt TV this past spring. "I hear it all the time, don't get me wrong, and once you hear it you're kind of like [looks up, thinking]. But for me, I love staying in the moment, and I'm one of those guys that would love to stick it out with one team my whole career.
"Kobe [Bryant], Tim Duncan, Dirk Nowitzki type. That's awesome," he said. "But you never know what the future holds sometimes and how teams may feel about you after a while, but I love it here and I would love to get my jersey retired here."
Training camps for both the Thunder and Wizards open Tuesday, with Durant cleared for full activity following an injury-marred 2014-15 season.
