BOSTON — What looked like an easy day for the Boston Celtics turned into a fight to the finish.

It's something they've got to clean up heading into the postseason.

Kyrie Irving just missed his second consecutive triple-double with 30 points, 11 rebounds and nine assists, Jaylen Brown scored 23 points with a key 3-pointer and the Celtics held off the Atlanta Hawks 129-120 Saturday after blowing a 25-point second-half lead.

Marcus Morris had 19 points and Jayson Tatum scored 18 for Boston, which has won six of eight.

Trae Young led the Hawks with 26 points, John Collins scored 20 with 11 rebounds, Taurean Price had 17 points and Vince Carter scored 16.

Irving had his second career triple-double in a win over Sacramento on Thursday.

It could have been a costly victory for the Celtics after forward Gordon Hayward suffered a strained neck early in the game and didn't return. Hayward banged his head into the shoulder of Atlanta's John Collins, who was setting a screen, and looked dazed before he went to the locker room.

Celtics coach Brad Stevens said Hayward was "woozy" from the hit and was sent home after halftime.

After Boston squandered the 25-point lead, Brown nailed his 3 from the right corner, sparking a 9-0 spurt that gave the Celtics a 121-112 edge with 3½ minutes left.

Suns 138, Pelicans 136: Josh Jackson hit a tying 3-pointer with 2 seconds left in overtime, New Orleans was assessed a technical foul when it called a timeout it didn't have, and Devin Booker hit the free throw to give visiting Phoenix the lead for good. Booker finished with 40 points to go with 13 assists, and Jackson, who had 19 points, scored the game's final point on a free throw after he was fouled on an inbound pass with less than a second on the clock. Elfrid Payton had 16 points, 16 assists and 13 rebounds in his fourth consecutive triple-double — all coming in the midst of New Orleans' six-game losing streak. Julius Randle had 21 points and 11 rebounds, but missed what turned out to be a pivotal free throw with 12 seconds left in overtime.

Wizards 135 Grizzlies 128: Bradley Beal scored 40 points for the second consecutive night and Washington beat visiting Memphis. Beal shot 12-of-17 from the field and made a career-high nine 3-pointers. The Wizards converted 17-of-35 from beyond the arc in a game that featured 20 lead changes. The Wizards, 11th in the Eastern Conference, moved within three games of eighth-place Miami. Jabari Parker had 20 points and 11 rebounds, and Bobby Portis scored 18 points as Washington improved to 3-1 on a five-game homestand. Mike Conley had 28 points and 12 assists for Memphis.
