In 2001–2002, Belbin / Agosto made their senior Grand Prix debut and won another silver medal at the U.S. Championships, which would have qualified them for the 2002 Winter Olympics if Belbin had been an American citizen. Instead, Belbin and Agosto were sent to all the other ISU Championships for which they were eligible: Four Continents, Junior Worlds, and Worlds. They won the 2002 World Junior Championships, completing their set of medals from that event. Following that season, Agosto aged out of juniors.
