IRVING (Texas) (REUTERS/AFP) - Sergio Garcia won the AT&T Byron Nelson in Texas on Sunday, matching the late Seve Ballesteros for most career victories by a Spaniard on the PGA Tour.

Garcia collected his ninth tour victory when he edged American Brooks Koepka in a playoff at the TPC Four Seasons in Irving.

"I won a bit a la Seve today. I wasn't really on," Garcia said in a greenside interview after finding two water hazards in the final round but still coming through to win.

Garcia carded a closing 68, while Koepka shot 71. They finished at 15-under 265, one stroke ahead of American Matt Kuchar.

It is Garcia's first victory on the PGA Tour since 2008, though the 36-year-old has continued to pile up victories outside the US.

World No. 2 Jordan Spieth's recent travails continued with a four-over final-round 74 that left him five off the pace.

Spieth, aiming to bounce back to form after his Masters meltdown last month and a missed cut at the previous weekend's Players Championship, struggled home with six bogeys and two birdies in his final 18 holes after starting the day in second place, two strokes off the lead.
