Sergio Garcia took out the AT&T Byron Nelson for his ninth PGA Tour win almost four years after his last following Sunday's play-off win over Brooks Koepka.
Garcia and Koepka could not be separated after four spectacular rounds as Jordan Spieth suffered yet another collapse on the final day to fall out of the race for victory at TPC Four Seasons.
Spaniard Garcia had far more play-off experience than his 26-year-old opponent and it showed as he took the win on the first play-off hole as he improved his record in extra holes to 5-6 with the victory, having parred the 18th to defeat Koepka and claim a second title at Byron Nelson.
A play-off was required after a mixed final round from Garcia and Koepka, who finished tied at 15 under through 72 holes, a stroke clear of Matt Kuchar (69).
Koepka entered Sunday's play with a two-stroke lead but carded a one-over-par 71 on a tough final day, as he bogeyed three holes, including two in a row on holes 15 and 16.
Garcia, meanwhile, rounded out a consistent PGA Tour tournament with his second one-under for the tournament as he beat par in every round, which proved enough to tie the lead with Koepka.
Despite the win it was a mixed bag from Garcia, who blended a superb front nine that featured four birdies and two bogeys with back nine which he parred after two birdies and two bogeys.
It was another day to forget for world number two Spieth as he entered the final round two strokes off the pace but hit a forgettable four-over to finish the event tied for 18th place.
Spieth bogeyed two of his first five holes and his day hardly improved from there.
He birdied the seventh but bogeyed holes eight, 12, 15 and 16 to fall out of the running once again, with the two-time major champion still searching for his first win since January.
Colt Knost (65), Spencer Levin (66), Charles Howell III (66), Robert Garrigus (66), Tim Wilkinson (68) and Bud Cauley (70) finished tied for fourth, two shots behind the leading pair.
