Adam Estes of Mattapoisett has qualified for the Junior Olympics National Championships to be held at North Carolina A&T University on July 22-28. Estes earned his spot in the prestigious meet following a second place finish at the Region I Championships at Icahn Stadium in Randall’s Island, New York on July 6. Estes, who competes for the Spartan Project, a first-year USATF club based in New Bedford and Southern Rhode Island, registered a shot put toss of 12.24 meters (40 feet, 2 inches) in the 15-16-year-old section to advance. Estes had a mark of 11.43 meters (37 feet, 5 inches), good for second position in the New England qualifier at Fitchburg State University on June 23. Over 8,000 athletes are expected to converge on Greensboro. A number of 2012 USA Olympians began their track and field career with involvement in the JO program.
