The Mavericks and forward P.J. Washington have agreed to a four-year, $90MM contract extension, ESPN’s Shams Charania reports. Washington’s new deal will run through the 2029/30 season.

The first year of the veteran extension will have a starting salary of $19.8MM, ESPN’s Bobby Marks tweets. That is the maximum allowed — a 140% increase of his $14.2MM salary for this season. It’ll add up to $88.8MM, Spotrac contributor Keith Smith tweets.

Washington will be ineligible to be traded during the upcoming season once he officially signs the contract.

The Mavericks have been locking up veteran contributors throughout the offseason. They also signed Kyrie Irving and Daniel Gafford to three-year extensions.

The Mavericks acquired Washington from Charlotte at the trade deadline in February 2024 and was a key part of the team’s run to the Finals that season, starting in all 22 games. Last season, the 27-year-old averaged 14.7 points, 7.8 rebounds, 2.3 assists, 1.1 blocks and 1.1 steals with shooting splits of 45.3% from the field and 38.1% on 3-pointers in 57 games.

In 390 career regular season contests, he’s averaged 13.1 points and 5.9 rebounds in 30.6 minutes per game.
