Zach LaVine hit a pair of go-ahead free throws with 2.1 seconds remaining to cap a 23-point effort, and reserve guard Denzel Valentine added 16 points to lift the host Chicago Bulls to a 110-109 victory over the San Antonio Spurs on Monday night.
San Antonio's DeMar DeRozan missed the back end of a 1-and-1 with 0.2 seconds remaining and missed a putback try at the buzzer as the Spurs lost their third straight game.
Chicago relied on seven double-figure scorers to earn successive wins for the first time since Dec. 18-21. LaVine scored 14 points in the final 12 minutes to help the Bulls erase a 10-point deficit.
DeRozan scored 36 points and grabbed 10 rebounds while Patty Mills added 25 points off the bench for the Spurs, who were playing without forward LaMarcus Aldridge, who was sidelined because of a sprained right thumb.
The Bulls prevailed in a wild finish. DeRozan hit a jumper over Kris Dunn with 8.6 seconds left to tie the score at 108, but LaVine drew a foul against Jakob Poeltl on Chicago's next possession.
Dunn fouled DeRozan when the Spurs got the ball back, but DeRozan hit only 1 of 2 foul shots. The Spurs were just 23 for 34 (67.6 percent) from the line for the game.
Poeltl notched a double-double of 16 points and 13 rebounds, while Trey Lyles chipped in 10 points.
Thaddeus Young and Tomas Satoransky added 13 points apiece for the Bulls, while Luke Kornet (12), Coby White (11) and Dunn (10) rounded out a balanced attack.
Valentine, who has spent much of the season in coach Jim Boylen's doghouse -- and therefore out of Chicago's regular rotation -- contributed four rebounds and three assists while shooting 6 of 10 from the field to tie his season high for scoring. Young and Kornet both grabbed nine rebounds.
San Antonio yielded six points in the final 41.9 seconds of the second quarter as Chicago took a 50-48 lead into halftime. Satoransky capped the Bulls' spurt with a steal and layup at the buzzer.
The Spurs led by as many as 11 points in the first half while limiting LaVine to four points on 1-for-8 shooting. Mills led all scorers with 12 points at the break.
San Antonio coach Gregg Popovich told reporters before the game that Aldridge did not travel with the team, remaining in San Antonio after suffering the thumb injury during Sunday's 110-106 loss to the Toronto Raptors.
Aldridge contributed 10 points and 10 rebounds against Toronto for his team-high 12th double-double.
Monday marked the third game Aldridge has missed this season. He was sidelined with right-thigh soreness in early December.
The teams are set to conclude the season series March 20 in San Antonio.
