Two-time Wimbledon champion Andy Murray said 2024 could be his final year before retirement after illness and injury hampered his preparation for the new season. Murray's year will begin at the Brisbane International as he builds up for the Australian Open later in January. The 36-year-old is ranked 42nd in the world after a frustrating end to 2023, when he won just one match in his last four tournaments. Murray has previously battled back from what seemed impending retirement after undergoing hip surgery in 2018.
