After winning the silver medal at the Italian Championships, Rizzo competed at the 2020 European Championships, where he placed seventh in the short program after some minor jump errors. Fifth in the free skate, he rose to fifth place overall, but remarked that it had been "a tough season for me because it’s between the Olympics." Rizzo was also assigned to compete at the 2020 World Championships, but these were cancelled as a result of the coronavirus pandemic.
