The Hubbells moved up to the senior level nationally and remained juniors internationally. They competed on the 2008–09 ISU Junior Grand Prix. At their first event in Mexico City, Mexico, they won all three segments of the competition to win the gold medal by a margin of victory of 17.26 points ahead of silver medalists Kharis Ralph / Asher Hill. The Hubbells were then assigned to their second event, the event in Cape Town, South Africa, where they again won all three segments of the competition to win the gold medal by a margin of victory of 9.25 points ahead of silver medalists Piper Gilles / Zachary Donohue. These two placements combined qualified them for the 2008–2009 ISU Junior Grand Prix Final, for which the Hubbells were the top-ranked qualifiers. Qualifying for the Junior Grand Prix Final also gave them a bye to the U.S. Championships.
