Jason Murray Kubler ( KOOB-l?r; born 19 May 1993) is a professional tennis player from Australia.
A former world number one junior, Kubler was often referred to as a "right-handed version of Rafael Nadal" for his powerful build and strong forehand.
Despite a promising junior career and predicted bright future in the sport, Kubler is yet to reach his potential as a professional due to a series of debilitating knee injuries.
