Lleyton Hewitt is once again set to reclaim the Australian No1 tennis ranking next month from Bernard Tomic.
Davis Cup and Grand Slams are what drive Hewitt and the former Wimbledon and US Open champion is refusing to put a time line on his retirement.
"I want to have another crack at Wimbledon for sure and I feel if I can get more matches under my belt going into Wimbledon that will hold me in a better stead," he said last month. "I don't know when I'll be stopping, but I'll be playing out the whole year regardless."
Turning 33 in February, though, and surely on his last legs after a series of career-saving surgeries, the former world No 1 must make way for the next generation sooner rather than later.
The father of three has led a seven-year - and often heartbreaking - crusade to return Australia to the Davis Cup World Cup for "one last crack" at winning the prestigious team competition he so covets.
But after drawing France away in February for a likely quarter-final shot at Rafael Nadal's nigh-unbeatable Spaniards on clay in Spain, Australia's stint back in the top tier looks set to be a cameo.
