The San Antonio Spurs (15-15) saw their four-game winning streak snapped as the Chicago Bulls rallied in the second half to beat the Spurs, 98-94.
The Spurs built a 21-point lead versus the Bulls only to see a collapse in the final two periods. The Spurs' offense sputtered in the third period (16 points) and fourth (15 points) as the Bulls took advantage of 15 San Antonio turnovers, scoring 12 points to complete the comeback win.
LaMarcus Aldridge paced the Spurs with 29 points and 12 rebounds and Marco Belinelli came off the bench for 17 points (5-7 from the three-point line) but it was not enough for the Spurs.

SAN ANTONIO (AP) — Chicago Bulls coach Jim Boylen proudly says he learned a lot from San Antonio coach Gregg Popovich during his two seasons as a Spurs assistant.
Boylen even learned how to withstand a crisis and it helped him beat his mentor.
Kris Dunn scored 24 points, Lauri Markkanen added 23 and the Bulls rallied from a 21-point deficit in the second half to stun the Spurs 98-93 on Saturday night.
"He has helped me grow as a coach and a man," Boylen said. "In a strange way, he's got a lot to do with this, too."
A Spurs assistant from 2013-15, Boylen is 2-4 since replacing Fred Hoiberg as Chicago's coach. His early tenure includes the Bulls holding a players-only meeting to air their dislike for Boylen's no-nonsense style.
But Boylen learned to be brutally honest and demand his team execute properly whether leading or trailing. Those instructions paid off Saturday.
"Coach Boylen had them ready and the character and fortitude they showed being down at half by 19 is a real tribute to what they are trying to establish in Chicago," Popovich said.
The Bulls outscored the Spurs 55-31 in the second half, including a 13-4 run to close the game.
The rally snapped Chicago's three-game skid and ended San Antonio's four-game winning streak.
"It shows a lot of heart from the team to climb back," Markkanen said. "Obviously, it takes a lot of energy to dig yourselves a hole and then we've got to climb back up, but it shows what we can do. If we play like that as a team, we have a chance to beat anybody."
LaMarcus Aldridge had 29 points and 12 rebounds for San Antonio, which dominated the first half. DeMar DeRozan added 21 points.
"They're going out there and just playing," DeRozan said. "When you play teams like that, they just go out there and play. They're not worried about losing. They just go out there and play hard."
Bobby Portis' nine-foot jumper with 1:39 remaining in the game gave Chicago its first lead since a pair of one-point advantages in the opening two minutes of the game.
Dunn added six points in the final 40 seconds to complete the come-from-behind victory for a Bulls team that struggled to gain any momentum in the first half.
"My team believes in me and it was a good team win," Dunn said.
Chicago committed only three turnovers in the second half, including just one in the fourth quarter when it outscored San Antonio 24-15.
"The key to the second half and the fourth quarter in general was our defense," Bulls point guard Ryan Arcidiacono said.
Arcidiacono finished with 12 points and six assists.
The Spurs led 62-43 entering the second half but promptly committed four turnovers in the opening two minutes of the third quarter.
"We were just a little bit more aggressive and we tuned in to the scouting report just a little bit more," Dunn said. "But I thought in the first half we played good defense, too, they just made tough shots."
Bulls: Guard Zach LaVine did not travel with the Bulls, missing the game with an injured left ankle. ... Forward Jabari Parker was in uniform but did not play.
Spurs: San Antonio guard Marco Belinelli, who finished with 12 points, made his first four 3-pointers and finished 4 of 5. Belinelli has twice made seven 3-pointers in a game this season, the most recent Nov. 19 at New Orleans. ... The Spurs entered the game shooting 83 percent on free throws, which would be the second-best total in league history if it stands. Boston set the league mark by shooting 83.2 percent in 1990.
HOME SWEET HOME
Boylen said it was very difficult to leave San Antonio to take another job in coaching, but he did keep a piece of his heart in the city. He still owns the house his family lived in when it was in San Antonio.
"I love San Antonio," Boylen said. "My kids, my wife and I, we loved living here. I just couldn't sell it. It broke my heart to put it on the market, so we kept it. We leased it to a beautiful family. It's in a Cul-de-sac, there's a pool, it's just a safe place. It's hard to get rid of a safe place."
Boylen met the family who leased his home for the first time Friday.
Spurs center Pau Gasol missed his 21st straight game with a sore left foot and his return is unknown.
"There's no contact or competitive stuff at all," Popovich said. "He's just shooting in place and that kind of thing. Seems like it's going to take a while."
