Grigor Dimitrov Retires from Brisbane Semi-Final

Grigor Dimitrov, the defending champion, retired from his Brisbane International semi-final match against Jiri Lehecka due to a groin injury, with the score at 6-4, 4-4. After receiving treatment, Dimitrov attempted to continue playing but withdrew, allowing Lehecka to advance to his fourth ATP final. Lehecka expressed concern for Dimitrov's health, hoping the injury isn't serious as the Australian Open approaches. The Czech player will face either Reilly Opelka or Giovanni Mpetshi Perricard in the final, both known for their powerful serves. This incident raises questions about Dimitrov's readiness for the upcoming Australian Open, given the timing of his injury. Meanwhile, in women's semi-final action, Polina Kudermetova advanced to the final after defeating Anhelina Kalinina.
