Jon Rahm donated $23,000 to the St. Jude Children's Research Hospital as the WGC-FedEx St. Jude Invitational continued a long charitable heritage in Tennessee.
The hospital was founded in 1962 and since then has worked tirelessly to prevent and cure children's cancer and other serious conditions.
The World Golf Championships may have been making its first trip to TPC Southwind this week but the US PGA Tour event played here has helped support the hospital since 1989.
And Rahm decided to make his own contribution, donating $1,000 for every birdie and $5,000 for every eagle he made this week.
A closing 69 left Rahm in a tie for seventh at ten under and after seeing his honorary young caddie from the hospital put the pin back on the 18th green, the Spaniard made his donation thanks to 18 birdies and an eagle over the four days.
We're playing for a lot more than just ourselves this week. I always think it's important to give back - Jon Rahm
"Any of the problems I'll ever have on a golf course are nothing, absolutely nothing compared to what some of those kids go through," he said. "To see their smile at least for five seconds taking care of the flag and people cheering for them, it's heartwarming, it's fun.
"I tried to get a smile out of him but he was a little bit nervous, too many people probably looking at him and too much attention, but he definitely had a little bit of a good time putting the flag in and walking around. It's all about that. It changed my attitude completely on 18, honestly.
"We're playing for a lot more than just ourselves this week. I always think it's important to give back.
"We have such a great tournament, such a great event thanks to the atmosphere that's created around this event and what we're playing for, that just giving back.
"It cost nothing to me, honestly. It's no effort and I'm just happy I can hopefully make somebody smile today."
