FORT WORTH, Texas _ In professional golf, victory is never assured until the final putt drops on the last hole of the Sunday round. Or during the playoff that follows.
With no maximum number of strokes for competitors on each hole, significant final-round leads can disappear quickly when the leader struggles or a pursuer goes on a well-timed birdie barrage.
The largest deficit overcome in one day at a PGA Tour event is 10 strokes, set in the 1999 British Open by Paul Lawrie. The biggest final-round rally by a champion at Fort Worth's annual tour stop involved a seven-stroke comeback, completed by Nick Price in 1994.
As golfers convene for the upcoming Dean & DeLuca Invitational at Colonial Country Club, we break down 10 of the largest Sunday rallies in tour history: five from other events and five that occurred at Colonial.
From a numerical standpoint, the five largest Sunday rallies in PGA Tour history occurred at other venues. Each covered at least eight strokes. Two of the five unfolded in major championships: Lawrie's 10-stroke comeback at the 1999 British Open over fast-fading frontrunner Jean Van de Velde and an eight-stroke rally at the 1956 Masters that allowed Jack Burke Jr. to defeat Ken Venturi.
Closer to home, Price's seven-stroke rally to win the 1994 Colonial in a playoff over Scott Simpson remains the largest single-round surge in tournament history and was the largest comeback on the 1994 PGA Tour. Here's a look at some Sunday comebacks for the ages in professional golf:
