BOSTON (AP) — Jayson Tatum scored 30 points and made six 3-pointers, and the Boston Celtics beat the Portland Trail Blazers 115-93 to snap a three-game losing streak Wednesday night.

Tatum’s 36th game this season with 30 or more points helped the Celtics avoid their first four-game losing streak. Derrick White added 21 points and five assists. Al Horford finished with 17 points, six rebounds and assists.

The Celtics played without big man Robert Williams for the third straight game as he recovers from a strained left hamstring. But they got back Tatum and Horford, who sat out Monday’s overtime loss at Cleveland nursing a sore knee and back, respectively.

Both were active during an 18-7 second quarter run that gave Boston a 53-35 cushion. The lead grew to 23 points (94-72) at the end of the third and as high as 27 the fourth.

Damian Lillard scored 27 points and had eight assists to lead the Blazers, who dropped to 14-20 on the road. Jerami Grant added 13 points.

Blazers center Jusuf Nurkic returned after a 14-game absence with a left calf strain. He’d been sidelined since Feb. 1. He started and had five points and six rebounds in 17 minutes.

Portland is 2-2 during its current six-game road trip.

The Blazers began the night 12th in the Western Conference standings, but very much in contention to make the play-in tournament. They had the same record as the Thunder (11th) and Pelicans (10th), and were just one game behind the ninth-place Lakers.

WILLIAMS MAKING TRIP

Williams will travel with Boston to begin its six-game road trip Saturday at Atlanta. Coach Joe Mazzulla said the hope is Williams will be able to return in the original 7 to 10 days that was projected after he was injured during the Celtics’ win over Brooklyn on March 3.

MOVING ON

Celtics forward Grant Williams said before the game he isn’t worried about any lingering effects after he missed a pair of potential go-ahead free throws in Boston’s overtime loss at Cleveland on Monday.

Before the shots, Williams was captured on camera jawing with Cavs All-Star Donovan Mitchell, telling him, “I’m going to make both of them.”

“I felt like I was super locked in and focused, even the confidence of saying you’ll make them both,” Williams told reporters. “It’s funny because when you say that and miss both, it’s even funnier.”

Williams had eight points, but missed his lone free-throw attempt.
