Parker shot a perfect 13-13 from the free throw line, and added 12 field goals on 24 attempts to pace the Spurs, who are in the midst of a nine game road trip while their arena is occupied by the San Antonio Stock Show and Rodeo.
Lou Williams came off the bench to score 22 points to lead the way for Philadelphia, while four other Sixers contributed double digit scoring efforts. Philly roared back from 83-71 down in the middle of the fourth quarter to come within five points of the visiting Spurs, but Parker proved to be too much down the stretch. His 37 points was his second best total of the season, having put up 42 in the Spurs recent win over Oklahoma City.
Philadelphia next plays host to Blake Griffin and the Clippers on Friday night.
