Jason Kubler Siblings: Meet Jonathan and Jade

Jason Kubler is an Australian professional tennis player. Despite a promising junior career, including reaching the junior world No. 1 ranking and being compared to Rafael Nadal, Kubler has spent the majority of his professional career on the lower circuits due to a hereditary knee condition that results in weakened meniscus around the joints.



Kubler was born in Brisbane, Australia, to a father who was from Australia and a mother who was from the Philippines. His father, John, began teaching Kubler how to play tennis when he was just five years old. John passed away from cancer when Kubler was eight years old.




Kubler spent his childhood in the neighborhood of Mango Hill, located in north Brisbane, together with his older brother and younger sister.

In 2009, Kubler achieved a milestone that had previously only been accomplished by Rafael Nadal: he won both the World Youth Cup and the Junior Davis Cup without dropping a single set.

Following his victory at the Junior Davis Cup, Kubler went on to win five consecutive titles, propelling him to the No. 3 spot on the junior rankings for the entire world.

Kubler was one of the pre-tournament favorites to win the Boys’ singles title at the 2010 Australian Open, where he entered as the third seed. However, he was defeated in the third round by fellow Australian and eventual runner-up Sean Berman. Berman went on to finish in second place.

Kristina Mladenovic and Ivan Dodig ranked sixth, and defeated Kubler and Fourlis in the final of the mixed doubles tournament, preventing them from becoming the first all-Australian team to win the mixed doubles championship since 2013.
