SAN ANTONIO — It's still early in the NBA season, but if the Boston Celtics can continue playing like they did Saturday in a 135-115 blowout of the Spurs, they're going to make a run at the Eastern Conference title.

Aggressive from the get-go, the Celts imposed their will on the Silver and Black at the AT&T Center and won their seventh consecutive game since losing their season opener.

Guard Jaylen Brown scored a season-high 30 points and backcourt mate Kemba Walker had 26, sparking a Boston effort that made short work of the tepid Spurs.

The Celts punished the Silver and Black inside, outscoring them 60-30 in the paint. The Spurs nailed 14 of 30 three-pointers, but they shot only 39.4 percent overall (39-99).

In the end, San Antonio simply couldn't offset Boston's inside punch. The 60 points in the paint were a season high for a Spurs opponent, as were the 135 points allowed. Boston led by as many as 24 points in the fourth quarter. 

"You have to bring your A-game," Spurs coach Gregg Popovich said. "I thought that we got intimidated to start and didn't play aggressively. They hit some shots, but I thought we were really soft defensively and it took its toll, because they came out aggressive and physical.

"We were better in the start of the second half, but too inconsistent and they played great. They deserved to win, obviously." 

Asked about Boston's dominance in the paint, Popovich said: "They just did it. They were great, they were aggressive."

The Spurs (5-4) end their three-game homestand Monday night against the Memphis Grizzlies.

DeMar DeRozan and Patty Mills led the Spurs' scoring with 22 and 20 points, respectively. Power forward LaMarcus Aldridge, who scored 39 points in a home win over Oklahoma City on Thursday night, finished with only three against the Celts.

Aldridge didn't make his only field goal of the game until 1.3 seconds remained in the third quarter. He finished 1 of 4 from the field and 1 of 2 from the free-throw line.

Popovich praised the Celts and their coach, Brad Stevens, when he was asked about the Spurs needing more from Aldridge on down nights.

"You need more from everybody on nights like this," Popovich said. "Boston is a talented group. Brad does a great job with them. They've been together for a little bit now. They're playing with aggressiveness and unselfishness that's top order."

Popovich wasn't expecting what he saw from his team Saturday.

"What surprises me is that we were so unaggressive and so unphysical against a team," Popovich said. "I mean, I was excited as hell. My team didn't seem to be as excited.

"I thought it would be a great night just to go compete against a talented team like that, that's going to be contending in the East. But we really didn't look like that."

Boston shot 51.1 percent overall (48-94) for the game and was 14 of 37 (37.8 percent) from the three-point line. Jayson Tatum and Marcus Smart scored 19 and 16 points, respectively, and Robert Williams added 11 on 5-of-5 shooting.

Every time the Spurs made a run in the second half, Williams took the wind out of their sails with rim rattling dunks that captured Boston's dominance in the paint.

Walker drained 4 of 10 three-pointers and Smart was 4 of 9 from long distance. About the only downer for Boston on Saturday was that right-handed forward Gordon Hayward broke his left hand in the first half.

Bryn Forbes (14) and Trey Lyles (10) rounded out the Spurs' double-figure scoring.

Boston led 39-30 after one quarter and was up 72-54 at the half. The Silver and Black outscored the Celts 37-32 in the third quarter, but by then, it was too little, too late.

Brown scored 20 points and the Celts knocked down 9 of 22 three-pointers to take their 18-point lead at the half. The Spurs hit 53 percent (7-13) from beyond the arc, but still got outscored 27-14 from long distance.

Boston, which led by as many as 19 points in the first half, shot 48.1 percent overall (25-52) and 40.9 percent from the three-point line.

Brown hit 6 of 9 shots, nailed his only three-point attempt and went 7 of 7 from the free-throw line. Smart (12) and Tatum (10) rounded out Boston's double-figure scoring in the first half. Smart made 4 of 9 shots, with all his attempts coming from beyond the arc.

The Silver and Black shot only 38.4 percent (16-44) in the first half.
