Kerry, who trains in Los Angeles with coach Tammy Gambill, scored 61.17 in his short program, completing the three required triple jumps including a triple axel, but was penalised 1.0 for a time violation in an otherwise strong performance.
Leading the event after the short program was Michael Christian Martinez from the Philippines on 64.03 points followed by Boyang Jin from China on 63.19.
Jin managed to lift to first position with a strong performance in the free program to win on 189.79 points. Russia's Adian Pitkeev was second on 187.19 with Shoma Uno of Japan and Martinez in third and fourth respectively.
Kerry was seventh in the free program, giving him a total score of 170.02 to finish fifth overall.
The result puts Kerry in a good position at the start of the season, as well as earning him 9 points on the Junior Grand Prix circuit which has six more events across Europe and Central America.
Kerry will be looking to qualify for the Sochi Winter Olympics at the upcoming Nebelhorn Cup in Germany at the end of September.
