In December 2006, Dennis became the youngest bowler ever to shoot a 300 game approved by the United States Bowling Congress. His age of 10 years, 2 months, and 27 days was 20 days younger than the previous record holder, Michael Tang, who bowled his at the age of 10 years, 3 months and 16 days on March 11, 2006. Dennis shot his 300-game during his Preps-Juniors League at Hillcrest Lanes in Columbus.
Dennis also uses an unorthodox-looking, two-handed delivery, which results in a large number of revolutions on the ball. The first game in his three-game set was a 240. His 300 game was the second game of his three-game series. His third and final game was a 232, bringing his three-game total to 772.
