It turns out Kris Humphries isn't just in the record book for his basketball skills. The Nets big man has held a U.S. National Age Group record in the boys 10-and-under 100-meter freestyle event for the past 18 years -- until this week.

That record, Swimming World Magazine reported, was broken by 10-year-old Winn Aung at a meet in California.

Aung, according to the article, swam the event more than a second faster than Humphries' record of 1:02.39, which was set in 1995.

Luckily for him, Humphries is still in the record books for the 50-meter free record in the 10-and-under division -- though according to the report Aung came close to breaking that one as well.

Though he grew up to be an NBA player, Humphries showed an enormous amount of talent as a young swimmer. In 2010, he told People Magazine that he beat Michael Phelps to be the top swimmer in the nation when he was 10.

"I was so good at a young age that I got a little burnt out," Humphries said at the time. "I also grew up in the Michael Jordan era ... for me, I watched [basketball] and saw it as a challenge. It's hard to stay focused on something when you have a ton of success at a young age, so I picked up basketball a little later and rolled with that."
