San Antonio rookie Dylan Harper scored 20 points, including seven in the final quarter, to quell Brooklyn's victory.
The Spurs improved to 3-0 after quietly unveiling a banner honoring longtime coach Gregg Popovich and his 1,390 regular-season wins. True to his humble personality, the Hall of Fame coach really wanted to hold a ceremony to commemorate or honor the banner, and the club heeded his words, as it has for three decades.
Cam Thomas scored 40 points to tie Kevin Durant for third on the Nets' career list with 10 40-point games, behind Vince Carter (17) and Kyrie Irving (14).
Michael Porter Jr. scored 16 points and Nic Claxton had 10 for Brooklyn, which remained winless to open its second season under coach Jordi Fernandez.
San Antonio committed four turnovers as Brooklyn took a 9-2 lead in the first three minutes. The Spurs responded by ending the first quarter with a 29-15 lead.
San Antonio led 81-55 with nine minutes left in the third, but Brooklyn ended the quarter with a 26-7 run to cut the lead to 88-81. Jalen Wilson's 3-pointer capped a 9-1 run to open the fourth, giving the Nets their first lead since the opening minutes at 90-89.
San Antonio went 10-0 to win the home opener.
The Spurs were without De'Aaron Fox (right hamstring strain), Jeremy Sochan (left wrist sprain) and Kelly Olynyk (left heel surgery). Backup center Luke Kornet joined that list of early injuries with a sprained left ankle suffered Friday in San Antonio's 120-116 win in New Orleans.
