2022: Professional debut
Blockx reached the third round and then quarterfinals of the junior events at Wimbledon and the US Open, respectively.[11] Shortly after the US Open, Blockx and sometimes junior doubles partner Gilles-Arnaud Bailly were invited to train with the Belgium Davis Cup team by captain Johan Van Herck.[12][13][14]
