BOSTON (AP)- After a two-month stretch between victories, the Philadelphia 76ers celebrated for the second time in less than a week.
Michael Carter-Williams and Henry Sims scored 24 points apiece and led the Sixers on a late surge that was too much for Boston to overcome in Philadelphia's 111-102 win over the Celtics on Friday night.
"We really wanted this win. I think it's a great win for us," said Carter-Williams, who scored seven points during an 11-4 run for the Sixers late in the fourth quarter.
Thaddeus Young and Elliot Williams added 15 points apiece for the Sixers, who have won two of four since tying an NBA record with 26 straight losses.
Philadelphia capitalized on 22 turnovers by Boston and overcame a triple-double by Rajon Rondo, who finished with 11 points, 16 assists and 11 rebounds for the Celtics.
"We're on a roll!" Philadelphia coach Brett Brown with a smile. "I'm just so proud of their ability to play as a team and continue to do the right thing and have a true desire to get better."
The Sixers held Boston scoreless for nearly four minutes late in the third quarter and scored 35 points in the fourth, pulling away while going 11-for-17 from the field and making 12 of 17 foul shots.
Sims led Philadelphia with 10 points in the fourth for a new career high in points.
"We just kind of turned it up a little bit. We just got more and more into guys and tried to stay aggressive on the defensive end," Young said. "It just shows progress and it just shows growth. This is a young team. A lot of guys, people don't really even know about but these guys are trying to make a name for themselves."
Celtics fans are getting to know the young Sixers well. Although Philadelphia has lost 28 of 31, two of the three victories have come in Boston.
Boston has lost seven straight and twice this season to Philadelphia, which has won just 17 games. The Sixers edged the Celtics 95-94 on Jan. 29, then didn't win again until beating Detroit last Saturday to avoid setting the longest losing streak in NBA history.
Jerryd Bayless scored 23 points for Boston and Brandon Bass finished with 12 points and 11 rebounds. Jeff Green added 15 points for the Celtics, who went 3-12 in March and fell to 0-2 in April.
"We have everything to play for," Rondo said. "We have pride as a team. Right now we're not displaying that at all."
After struggling through the second quarter, the Sixers kept it close until pulling away late in the third and never allowing the Celtics to retake the lead.
"I'm sure they've had their down moments, obviously, throughout their losing streak, but tonight wasn't one of them," Boston coach Brad Stevens said. "They played well. We played not well. That's that."
Philadelphia closed the third period on an 11-2 run and led 76-71 entering the fourth quarter. The Sixers held Boston without a point for nearly four minutes in the third before Kelly Olynyk ended Boston's drought on a putback with 14 seconds left.
Philadelphia opened the fourth on a 6-2 run and held a nine-point lead three different times before the Celtics made a run and cut the lead to 89-86 on a three-point play by Green with 6:04 left to play.
Carter-Williams got the Sixers running again with a layup, then took a steal in for another layup and scored seven during an 11-4 run that put Philadelphia in command at 100-90 with 2:21 remaining.
After opening the game 2 for 11 and committing seven turnovers in the first quarter, the Celtics overcame the sluggish start in the second period and outrebounded Philadelphia 16-8. Trailing 31-28, the Celtics came up with back-to-back offensive rebounds on one possession before Bayless hit a 3-pointer to tie it.
