San Antonio Spurs snatched a dramatic 129-127 win over the Golden State Warriors after Manu Ginobili sunk a three-pointer with 1.2 seconds left of second overtime.
The Spurs and the Warriors had gone toe-to-toe throughout an enthralling opener to their Western Conference semi-final series.
The Warriors, though, must have thought they had done enough as they led 127-126 - with 44 points coming from Stephen Curry.
However Ginobili's winning basket and a 28-point haul from Tony Parker saw the Spurs move 1-0.
Nate Robinson scored 27 points as the Chicago Bulls struck the first blow in their Eastern Conference semi-final series with the Miami Heat, claiming a 93-86 win in game one.
The Bulls' win was built on a 35-point fourth quarter, with Jimmy Butler contributing 21 points and 14 rebounds.
LeBron James had 24 points, eight rebounds and seven assists to lead the Heat.
