The competition is free to enter and open to both boys and girls, with youth competing in pitching, hitting and running drills under eight different age divisions for both baseball and softball. Participants must qualify for the national finals by first advancing through three levels of competion.
Hammill came away victorious in the age 11/12 baseball category on Saturday for a second consecutive year, wowing the audience with his agility around the bases and his ability to hit for power.
"It felt really good," said Hammil, a fan of Jose Bautista and the Blue Jays. "All the hard work I put into this moment really paid off and it feels amazing."
"Once I did the hitting drill, I saw how far I hit and thought that maybe I would have a bit of an edge. And then when I did my running, I felt good and it made me confident I had a good chance."
Known as the "Official Youth Skills Competition of Major League Baseball," the program is celebrating its 20th season and is a part of Major League Baseball's Play Ball initiative, which encourages widespread participation in all forms of baseball activities among all age groups.
