(AP) - Tim Duncan scored the first five points of overtime, and the San Antonio Spurs rallied from an 18-point deficit to beat the Memphis Grizzlies 104-93 Saturday night and move a win away from the NBA Finals. The Spurs grabbed a 3-0 lead in the Western Conference finals and now have won five straight this postseason. With the memory of blowing a 2-0 lead a year ago in the West finals to Oklahoma City, when they lost the next four, the Spurs shook off their sloppy play early and pushed the young Grizzlies to the edge of elimination in the first West final played in Memphis. San Antonio, which didn't lead this game until the opening minute of the fourth quarter, can wrap up the series Monday in Memphis.
