Reilly Opelka stuns Novak Djokovic in Brisbane quarterfinals

In December, Reilly Opelka stunned Novak Djokovic at the Brisbane International, winning 7-6 (6), 6-3 in the quarter-finals. This defeat was particularly significant for Djokovic, as he was aiming for his 100th tour-level title. Opelka, a 27-year-old American, delivered an impressive performance, serving 16 aces and gaining confidence by taking risks against the world's best player. Djokovic, the 24-time Grand Slam champion, was playing his first tournament of the year and had arrived back in Melbourne to start his preparations for the Australian Open, where he hopes to extend his record of 11 titles in the event. Andy Murray has officially joined Djokovic’s coaching team and has begun to assist him in his preparations for the major tournament. Djokovic expressed gratitude for Murray's meticulous coaching approach and perspectives, which have arisen from their past rivalries. Their collaboration started after Murray's retirement, and the two players worked together during the off-season, contributing to Djokovic's training strategy for the Australian Open, commencing January 12. Despite the defeat, Djokovic remains a feared competitor in the sport, especially with his track record in Grand Slams. With a world ranking progression contingent on performance in the upcoming matches, this loss in Brisbane may pose challenges for Djokovic but also offers opportunities for growth moving forward.
