FINAL

Celtics 135, Spurs 115

Boston kept San Antonio at arm's reach for virtually the entire second half, handing the Spurs a defeat they'll be looking to forget as soon as possible.

This is just the second win the Celtics have notched against San Antonio since the 2011-12 season.  

---

With 5:01 to go in the game, the Spurs' hope of stringing together consecutive wins are looking grim. Boston maintains a 20-point lead, not allowing the home team to creep closer as the minutes wind down. 

Third Quarter

Celtics 104, Spurs 91

The third period was the first one in the matchup that went the Spurs' way; the home team outscored the visitors 37-32, but Boston still has a sizeable cushion heading into the final dozen minutes. 

San Antonio has given up at least 32 points in each quarter of Saturday's game. 

---

With 7:12 to go in the third quarter, San Antonio hasn't made much of a dent in the lead of the Celtics, who remain ahead by a score of 82-68. DeMar DeRozan continues to be the Spurs' biggest contributor; he has five of the Spurs' 14 points this quarter, and 19 for the matchup. 

Halftime

Celtics 72, Spurs 54

It was a half to forget for San Antonio, who were dominated by visiting Boston in the first half to the tune of an 18-point halftime deficit. 

DeMar DeRozan is the only Spur with double-digit points at halftime, with 14. On the other side of the court, three Celtics are in double-digit points, led by Jaylen Brown's 20. 

San Antonio has a slight edge on three-point shooting, but the Celtics have also made nine more attempts from beyond the arc. 

LaMarcus Aldridge has a lone point. 

---

After his 39-point outburst on Thursday, LaMarcus Aldridge is having another slow start against Boston. With minutes to go until halftime, he's been held scoreless with only three shot attempts and no trips to the charity stripe. 

Boston continues to lead, 55-41, with 4:27 left in the half. 

---

Boston has ballooned its lead to 15 over four minutes into the second quarter, and San Antonio is still searching for its first field goal of the quarter, having sunk four free throws. Their first-half performance is part of a trend. 

First Quarter 

Celtics 39, Spurs 30

Not what you want to see in the first quarter of a potential early-season statement game for the Spurs, giving up nearly 40 points to a playoff contender at home. 

The Celtics limited San Antonio to 38% shooting from the floor while making a scorching 58% of their shots. San Antonio had to go 9-9 from the charity stripe to keep the deficit from being double-digits at the end of the opening period. 

DeMar DeRozan and Bryn Forbes both have six points for the home team. 

---

With 6:54 to go in the quarter, San Antonio has taken a timeout after a 7-0 run by Boston vaulted them up front. They lead, 16-10, led by Jaylen Brown's game-high seven points. 

---

Bryn Forbes managed to sink all three free-throw shots after being fouled by Kemba Walker early in the first period, helping to stake San Antonio to an early 10-9 lead. 

Boston and San Antonio have combined to make seven of their first 15 shots from the field. 

---

San Antonio is off to a fast start at the AT&T Center Saturday afternoon, scoring the first seven points of the game and making sure to put a hot Celtics squad on their heels early. Boston's Jaylen Brown finally put his team on the board 1:41 into the game. 

The score is 7-2 in the early going, advantage the home team. 

Pregame

As the Spurs continue a homestand that started with a win over the Thunder Thursday night, a key cog of the rotation will be looking to build off the momentum of his 39-point performance. 

LaMarcus Aldridge was having a slow start to the 2019-20 season until that breakout, which helped lift San Antonio to a 121-112 win over Oklahoma City. 

"LaMarcus, obviously, was a beast," Popovich said after Thursday's game. "He was really good. He shot quickly, he made quick decisions and he also passed it out of there when he got doubled or there was a crowd."

Now Aldrige and the Spurs face one of their toughest tests of the young season: A 6-1 Boston squad that hasn't lost since their first game. But the Silver and Black have had the upper hand against the Celtics as of late; in their last 15 head-to-head matchups dating back to the 2011-12 campaign, Boston has won only once. 

Tipoff is at 4 p.m. CT Saturday.
