JaVale McGee had 22 points and eight rebounds, and John Wall dished out 14 assists as the Washington Wizards routed the Detroit Pistons 98-77 on Sunday night.

Detroit entered on a season-best four-game winning streak, but saw it end when the Wizards went on a 22-2 run that spanned the third and fourth quarters.

Nick Young added 22 points for the Wizards. Greg Monroe had a game-high 27 for Detroit.

The game was tied at 45 at the half, and the Wizards took a 62-61 lead late in the third quarter on Wall's first points of the game. Two straight Detroit turnovers let Washington quickly build the lead to five, and it was 74-63 by the end of the quarter.

Things got so bad for Detroit during Washington's run that rookie point guard Brandon Knight's mask came loose, and he ended up tossing it to a fan. An arena employee retrieved the mask at the end of the quarter.

Knight left the mask off, but it didn't help, as the Wizards scored the first seven points of the fourth to move the margin to 18.

Washington led by as much as 27 in garbage time.

Notes: Ben Wallace played in his 1,054th career game, tying Avery Johnson's record for career games by an undrafted player since the NBA/ABA merger. ... Monroe, averaging a double-double, didn't get his first rebound until the final minute of the first half. ... Rashard Lewis (knee) returned after missing three games, but didn't play until the second half. He surpassed 15,000 career points with a free throw midway through the fourth quarter.
