Jordan Spieth began the final round of the Masters nine shots behind leader Patrick Reed.
But when Spieth converted this long birdie putt at the par-3 16th and Reed missed a 5-foot birdie try at No. 13, the two were suddenly tied at 14 under.
That putt got Spieth to 9 under for the day.
The largest 54-hole deficit overcome in Masters history was eight strokes. That happened when Jackie Burke Jr. defeated Ken Venturi by one stroke in 1956.
