Bubba Watson, who spoke emotionally about ill father, Gerry, at both the PGA Championship and Ryder Cup, announced via his Twitter account that his dad had died Thursday due to throat cancer.
The PGA Tour also confirmed Gerry Watson's death.
"Everyone, it's a sad day for my family!! My Dad has passed,'' Watson wrote. He later added: "My dad got to see me win & play for USA in the Ryder Cup!!!! Gods plan is always right! Golf gave my family my best year & worst year!!''
Watson won his first PGA Tour event in June at the Travelers Championship, prevailing in a playoff over Scott Verplank and Corey Pavin. He broke down after winning and later told reporters he was thinking about his father.
Watson lost in a playoff at the PGA Championship to Martin Kaymer, but secured a spot on Pavin's U.S. Ryder Cup team in the process.
The Ryder Cup in Wales was especially emotional for Watson, who spoke of a team dinner where Pavin invited Maj. Dan Rooney, a decorated F-16 pilot (and a PGA golf professional) to talk to the team.
"My dad was a military man,'' Watson said in Wales. "He was in Vietnam. He (Rooney) gave us a special present last night. It meant a lot. My dad is dying of cancer; the doctor says three months to live. I'm playing this for him.''
Watson won his first match but lost his last three in the 14½ to 13½ European victory.
This year on the PGA Tour, he had four top-10 finishes and earned more than $3.1 million.
