Kyrie Irving took over on Thursday night, scoring 20 points in the final minute of regulation and the five minutes of overtime.
Irving took over the game late, including making a falling away three-pointer with less than two seconds left to send the game into the extra period.
That shot game after he had just drained two other three-pointers to cut the Spurs lead to three.
That, combined with the Spurs missing a number of free throws, left the possibility of overtime if the Cavaliers could make another three.
And Irving stepped up and hit it.
The game ended at 127-124 in overtime, after Irving scored some more points and LeBron James chipped in a few as well.
Irving’s 57 points set a new career-high.
