At the Real Club Valderrama, the Spaniard fired a final-round 66 to tie the leader Lahiri after trailing him by seven strokes.
Garcia won the sudden-death play-off with a par putt on the second hole, earning him £3.15 million in prize money and his first LIV victory.
“Without a doubt [one of the highlights of my career],” Garcia stated.
He mentioned that it was a significant Sunday for Spanish sports, adding, “Carlos’ victory is another plus. Today at Wimbledon, Alcaraz triumphed.
I hope Spain triumphs this evening. That would be an amazing weekend. However, I performed admirably during the playoffs. It’s just that kind of hole. But very joyful.”
Garcia was even more delighted when Spain defeated England in the Euro 2024 football final, capping a historic day of national accomplishment.
Garcia had won the 2020 Sanderson Farms Championship, which was his most recent success.
Tyrrell Hatton of England placed third on four under, one stroke behind the leaders. Patrick Reed of the United States and Louis Oosthuizen of South Africa shared fourth place on three under.
