Ginobili came off the bench to spark San Antonio, scoring 16 points on 5-of-10 shooting. He also hit a dagger midrange shot with 27.6 seconds remaining to force a Game 5 in Oakland.
"We were all fired up, and we saw we were in a great situation to get that win when we needed it," Ginobili said. "Now, we have a few hours to feel good about this win, and tomorrow, we'll start thinking about Game 5."
Parker and Ginobili have won four NBA championships together since 2002. Parker was the No. 28 overall pick in the 2001 NBA draft and Ginobili was the No. 57 overall pick in the 1999 NBA draft, although opted to play oversees until joining the Spurs in 2002.
