PHILADELPHIA (AP) -- As the 76ers' lead grew, the fans got louder, the fourth quarter a bit more wild. It didn't get unpredictable. At least, not to anyone on the Spurs. Tim Duncan and Tony Parker have thrived in situations more uncomfortable than trailing on the road in the fourth against a sub-.500 team. Duncan and Parker pushed back hard-charging Philadelphia late in the game to lead San Antonio to its fifth straight win, 90-85 over the Philadelphia 76ers on Monday night. Duncan had his fifth double-double of the season with 24 points and 17 rebounds and Parker had 20 points. The Spurs blew a 17-point lead in the first half before rallying late in the fourth to win again without guard Manu Ginobili. Ginobili is still out with a strained left hamstring. After the Sixers turned the 17-point hole into a seven-point lead, the Spurs got it together. Kawhi Leonard dunked off a turnover, then buried a 3 off a defensive board to tie it 88-all. Duncan's jumper made it 84-82 and Parker swished one the next time down. ''We called a couple of things down the stretch that Tony and Timmy have been running for over a decade now,'' coach Gregg Popovich said. ''The balls, they went in.'' For the Sixers, the balls went out: They missed nine of their final 10 shots and the Spurs closed the game on a 15-3 run. ''When you've been playing a long time, and you have a great coach, you know what to do,'' Parker said. The Sixers seems lost. Evan Turner had 18 points and 12 rebounds, but the Sixers still lost for the seventh time in nine games. Andrew Bynum, out all season with knee injured knees, said before the game he remained on target to return around the All-Star break. The Sixers could use him. Without their best player, they've slumped to seven games under .500. Without Ginobili for the fourth straight game, the Spurs got clutch baskets down the stretch to win their NBA-high 15th road game. After a miserable first half, the Sixers turned to Spencer Hawes and Nick Young off the bench to come back. The Sixers erased the early 17-point hole with three straight big baskets in the fourth. Royal Ivey pulled them within two, Turner's 14-footer tied it at 73-all and Hawes put them ahead for the first time in the game with a 17-footer that made it 75-73. Thaddeus Young's short jumper put the crowd of 15,346 on their feet and stirred up the ''Defense!'' chant for the first time all game. Nick Young's 3-pointer and long jumper gave the Sixers a seven-point lead. But then the sloppy play took hold. Easy missed shots. Turnovers. Duncan blocked Jrue Holiday's layup. ''We recognized there was time left in the game,'' Duncan said. ''We had to tidy up on the defensive end and get some stops. We did just that.'' Just like that, game over. ''We didn't finish them off,'' Thaddeus Young said. ''We've just got to figure out a way to get past those kinds of teams. We're trying to make runs, we're trying to get wins, we're trying to get wins.'' Led by Duncan, the Spurs took control of this one early and raced to a 17-point lead in the second quarter. At last in the third, the Sixers came ready to play, showing the sharp shooting touch that abandoned them in the first half. Hawes, who scored 16, buried a 3 as part of an 8-0 run that sliced the gap down to four. Young, however, missed two free throws that would have inched the Sixers closer. As they do, the Spurs took advantage of the missed opportunities from the line. Parker pushed them back with a jumper and Leonard's thunderous dunk quickly made it 61-49. They just couldn't put away the Sixers that easily. Maybe the outcome would have been different with Bynum. They'll need him in their playoff push. ''We're very concerned,'' coach Doug Collins said. Bynum, their big offseason acquisition, again expressed optimism he'd finally be ready to play around next month's All-Star game. Bynum has sat out the season because of bone bruises on both his knees. He practiced jump shots with the Sixers at the morning's shootaround and insisted he was pain free. Bynum, a free agent at the end of the year, has no intention of rushing back. There's still plenty he has to work on before he's cleared. ''It's going to be defensive slides, cutting, running full speed and stopping, backpedaling, jumping,'' he said. ''Explosive stuff.'' Bynum wasn't the only reason the Sixers' locker room was buzzing before the game. Former great Charles Barkley - his retired No. 34 hangs in the rafters - called the game for TNT and was a pregame visitor. Barkley received a huge standing ovation when the Sixers aired a video tribute to him. NOTES: The Spurs won for the 14th time in 17 games. ...
