Andy Murray came back to the tour in the second half of 2019 after undergoing hip surgery in January, but has fallen outside of Top 500. Only playing six tournaments last year, and seven so far this year, it's been a tough road for the former No. 1.

But, every new week, and new season, begets a new start, and Murray may be ready to make 2020 his year on the comeback trail. This week, the 32-year-old competed in the China Open, where he reached the Beijing quarterfinals before falling to top seed Dominic Thiem.

With less than two months left in the 2019 season, it's time to start looking towards next year and the comeback, or possibly end, of Murray's career.
