WASHINGTON (AP) -- After struggling defensively this season, the Washington Wizards took advantage of another team's guarding woes.
Austin Rivers had 12 of his 18 points in the fourth quarter for the Wizards, who shot a season-high 56.7 percent (51 of 90) in a game between the league's second- and third-worst defenses entering Saturday.
Both teams shot about 62 percent in the first half, but the Wizards held the Pelicans to 17 of 48 from the floor (35.4 percent) after the break.
''We just did what we needed to do, and that was all on the defensive end,'' said Wizards guard Bradley Beal. ''We accepted the challenge of guarding them and taking away the 3-point line. They made a lot of them tonight still. But it was our defense that won us the game.''
Beal also had 18 points, one of six Wizards to score in double figures on a night the Pelicans were without injured All-Star forward Anthony Davis.
Julius Randle tied a season high with 29 points and grabbed 15 rebounds. He started in place of Davis, who was ruled out during pregame warmups after straining his right hip in Friday's loss at the New York Knicks.
Nikola Mirotic added 22 points and E'Twaun Moore had 19 as the Pelicans finished a three-game road trip winless, sinking to 2-9 on the road overall and 0-4 without Davis this season.
''Our defense is atrocious right now,'' said Pelicans coach Alvin Gentry. ''Especially on the road. You're not going to be able to win games on the road until you can at least control the ball somewhat and take away all the driving lanes and take away the open 3s.''
In a game with 14 lead changes, New Orleans held the advantage early in the fourth quarter before the Wizards used a 15-5 run to pull away.
Porter tipped in a miss and then slammed in Wall's alley-oop feed to put Washington up 113-104 with 5:15 left, the largest lead in the game to that point.
Rivers added a pair of runners to close the stretch, giving Washington a 119-107 lead with 2:06 to play, sealing a win that came despite continued team struggles from beyond the arc. Washington went 10 of 29 from 3-point range and only 3 of 13 after halftime.
''We had a lot of 3s that wasn't falling,'' Wall said. ''But guys did a better job of just attacking on their (defensive) switches in the second half.''
''I think they just had trouble keeping us out of the paint,'' Rivers said of the lineup. ''It's a tough lineup to guard. We had four guys who can attack the basket, and then our fifth guy is Kieff, who can spread the floor. There's really no stopping us. It's really on us to make shots at that point.''
Davis returned in the fourth quarter Friday in New York after hurting his hip in the third, but was held out of the back end of the Pelicans' fourth back-to-back game set this season. It's unclear if he'll be available for New Orleans' next game on Monday.
''We don't know,'' Gentry said. ''Obviously, he'll work out tomorrow and have some rehab tomorrow.''
