John Wall signs $170 million extension

WASHINGTON (AP) - The Washington Wizards have signed John Wall to a $170 million, four-year contract extension that begins in 2019-20.

Team President Ernie Grunfeld announced the completion of the deal Wednesday. Wall said in a video posted on Twitter on Friday that he had agreed to the extension.

Wall's deal includes a player option for the final season in 2023-24.

Owner Ted Leonsis said extending Wall gives the Wizards stability for years to come. The team also matched a $106.5 million, four-year offer sheet that forward Otto Porter Jr. signed with the Brooklyn Nets and has guard Bradley Beal signed through 2020-21.

Wall, a four-time Eastern Conference All-Star, is the third player this summer to get a designated player "supermax" extension, joining Houston's James Harden and Golden State's Stephen Curry.
