Down and dominated during most of the first two games at home, the San Antonio Spurs once again showed why nobody should ever count them out. Tony Parker scored 25 of his 32 points in a sizzling first half, Tim Duncan added 23 points and 10 rebounds, and the Spurs quieted the Golden State Warriors and their rowdy sellout crowd in a 102-92 victory Friday night to take a 2-1 lead in the Western Conference semifinals.
