Kei Nishikori has openly criticized himself after suffering a disappointing loss to Rafael Jodar at the Mubadala DC Open. The former world No. 4, who has faced numerous injuries in the latter stages of his career, expressed frustration, stating he might 'end up hating tennis'. Nishikori's recent performance has been lackluster, as he has only participated in four Challenger-level tournaments since the Australian Open, causing him to fall outside the ATP Top 500 rankings. This loss adds to the mounting pressure on the veteran player as he contemplates his future in the sport.
