Jon Rahm, RYDER CUP's star, revealed that he was born with a condition called clubfoot and had to have every bone in his foot broken.
The 26-year old has reached the top of men's golf and will be leading Europe's fight against the USA at Whistling Straits.
Jon Rahm said he was born with club feet
He was ranked world number one last summer, and he won his first major in dramatic fashion at the US Open earlier in the year.
The Spanish golfer, however, had to overcome a severe injury and had to adjust his golf swing.
Rahm stated that Rahm was born with a clubfoot on his right leg. This means that my right leg from the ankle to the foot was straight. My foot was 90 degrees inside out and basically upside-down.
"So they basically broke every bone in my ankle when I was born and I was cast within 20 minutes from the knee down.
"It seemed like every week I was required to return to the hospital to be recasted. My leg didn't grow as fast from my knee down.
"So my right leg has very limited mobility at the ankle. It's a centimetre-and-a-half shorter, as well.
"So, what I mean when I say limitations is that I didn't take full swings because my right ankle doesn’t have the stability or mobility to do so.

Rahm said, "I learned very early that I was going to be more efficient in creating power and consistent from a short strike.
"A full to parallel is faster than a normal one, but it doesn't give me stability. It's too much for my ankle.
"Also my wrists aren't very mobile, so I naturally bend my wrist to make power in all the sports I play.
"So, that's why I bow my wrist when I swing and that's how it hits me. These are the little things I believe a lot people can learn.
"Let your body decide how you can swing. It's as simple as that.
Europe and Rahm will try to keep the Ryder Cup that they won in Paris three years ago.
The showdown in Wisconsin with the American team begins Friday. It was postponed last September because of Covid.
