Just 1.7 seconds is all that remained for Tim Duncan, Manu Ginobili and Tony Parker in what has been a wasted and humiliating dud of a playoff run.

An undrafted rookie didn't let them go down that quickly.

Catching the inbounds pass with 1.7 seconds left, Gary Neal forced overtime with a spectacular 3-pointer in the face of O.J. Mayo as time expired, and the top-seeded San Antonio Spurs staved off elimination by stunning the Memphis Grizzlies 110-103 on Wednesday night.

The straightaway 3-pointer was the second of two remarkable San Antonio baskets in the final 2.2 seconds of regulation. Manu Ginobili, who scored 33 points, hit the other with a long corner jumper while falling out of bounds in front of the Spurs bench, in what was originally ruled a 3.

Randolph led Memphis with 26 points and 11 rebounds. He scored 18 points in the fourth quarter and overtime, but the Spurs assured a Game 6 in the overtime behind Parker, who scored 6 of his 24 in the extra period.

Only eight teams in NBA history have ever come back from a 3-1 deficit. The Spurs, who were the NBA's winningest team for most of the season, are desperate to join that list in what may be their last good shot to win a fifth championship in the Duncan era.

The eighth-seeded Grizzlies lead the best-of-seven series 3-2. They will host the Spurs on Friday night.
