(CNN) It's not very often that Michael Phelps gets knocked off the record board. But a 10-year old swimming phemon with a superhero name has done just that. Over the weekend, Clark competed at the Far West International Championship in California, where he won the 100-meter butterfly in 1:09:38. That's more than second better than the 100-meter butterfly record that Phelps set at the championship in 1995. It had gone unbroken, while Phelps went on to win 28 Olympic medals.
