Tobias Harris scored 23 points, Nikola Vucevic added 19 points and 13 rebounds, and Afflalo had 17 points for Orlando (19-45). Maurice Harkless added 12 points and 10 rebounds for the Magic, who were swept in the season series.
The Magic led by as many as seven points and last led 67-66 with 8:15 remaining in the third quarter. But they were able to stay within 10 points for much of the game.
"Just overall our mental toughness," Vaughn said. "That's what you have to lean on, on the road is being able to fight through."
San Antonio struggled to contain seven-foot center Nikola Vucevic, who hit a series of short jumpers, layups and hook shots against Splitter and Duncan. The third-year pro out of Montenegro was 8 for 16 from the field.
After attacking the paint in an explosive start against the Heat in their previous game, the Spurs were less aggressive and effective against the Magic. San Antonio started 2 for 6.
A timeout by Popovich midway through the first quarter changed that. Parker drove the lane on three consecutive possessions following the timeout, scoring consecutive layups and having his third attempt trickle off the rim.
"Pop was a little bit worried we would have a slow start after such a big win against Miami," Parker said. "We just wanted to make sure we didn't come out flat. So, I was very aggressive from the get-go to make sure I had a good start."
NOTES: Spurs P Jeff Ayres (sprained hand) was originally listed on the pregame roster as not playing, but was cleared later in the day. He did not play, however. . Magic rookie G Victor Oladipo (sore left ankle) missed his second straight game after playing in the team's first 62. ...

Before the game, Popovich walked over to the Orlando bench to greet Vaughn. . Popovich was asked if he would consider becoming a studio analyst once his coaching days are over. "Just watch one of my end-of-quarter interviews and I think that will answer your question concisely and accurately," Popovich said, attempting to stifle a chuckle. ... San Antonio celebrated the 31st anniversary of its mascot, the Coyote, throughout the game. On hand for the celebration were the Portland Trail Blazers' mascot, Blaze, and Rocky of the Denver Nuggets.
