OAKLAND, Calif. -- The Memphis Grizzlies didn't play like a team chasing a postseason spot.
"We feel that every game from here on out we have to come with the purpose that it is a playoff game," Grizzlies guard Mike Conley said. "We've got to win these games to have an opportunity. We let this one slip away."
Monta Ellis added 21 points for the Warriors, who snapped a three-game losing streak. Corey Maggette and Anthony Tolliver each had 12 points and Chris Hunter, making his sixth start, recorded his first career double-double with 10 points and 10 rebounds.
"You've got to be aggressive," Hunter said. "You can't worry about getting into foul trouble."
"We were sleepwalking the first half," Conley said. "They were being aggressive and making shots. We just didn't play defense in the first half."
All-Star Zach Randolph finished with 16 points and five rebounds before leaving in the third quarter with a sore left ankle.
The ninth-place Grizzlies fell 4 1/2 games behind No. 8 Portland in the Western Conference with 10 games remaining. Memphis never led after the 9:18 mark of the first quarter as the Warriors went on to shoot nearly 55 percent for the contest.
"We didn't play any defense, nobody," Mayo said. "It's not about the offense. We gave up 78 points in the first half -- enough said."
Warriors coach Don Nelson pulled within three wins of Lenny Wilkens (1,332) as the NBA's all-time winningest coach.
Hasheem Thabeet crashed into Maggette under the Warriors' basket early in the third quarter, causing both players to fall to the floor, stunned for a minute or so. Maggette eventually jumped up and began arguing with an official about the no-call, which earned him a technical foul.
Williams scored 20-plus points in back-to-back games for the first time in his career.
The Grizzlies got within 12 points entering the final minute of the third quarter, but a flurry of 3-pointers from Williams, Curry and C.J. Watson upped the lead to 20 before Conley, who also had nine assists, hit a 3-pointer at the buzzer to make it 103-86 entering the final period.
"We got a little quick with our shots and they were back in transition," Curry said. "We didn't know exactly how to handle it and that's when they got back in it. Luckily we made another charge and sealed the deal."
The Warriors shot better than 61 percent (16 of 26) in the second quarter to take as much as a 27-point lead before settling for a 78-56 halftime lead.
"Between bad offense and bad defense they were able to increase that lead," Grizzlies coach Lionel Hollins said.
