Kevin Anderson's recurring injury bogey resulted in the last-minute withdrawals from the recent Doha and Acapulco ATP tournaments - but the 34-year-old, one-time world number five is not thinking of quitting just yet.
Indeed following on the confirmation from ATP media manager, Joshua Rey, of Anderson's latest frustrating knee and hip predicaments which have dogged him for more than two years, Anderson, South Africa's former US Open and Wimbledon Grand Slam finalist, but now ranked 91, proclaimed in an interview with IMG Tennis that "Tennis is my passion. There is still a lot in this sport that I want to achieve."
But, of course, in the meantime Anderson has been overshadowed as South Africa's number one tennis player by the burgeoning, 24-year-old, Cape Town-born Lloyd Harris, who this past week scaled new heights while beating world top players Dominic Thiem, Denis Shapavalov and Kei Nishikori to reach the competitive ATP 500 tournament final in Dubai and improve by no fewer than 29 positions a career-best 52nd world ranking.
Harris, in the process, not only became the first qualifier to reach the Dubai final, but a qualifier had never previously progressed to the semi-final stage of the event.
Anderson's decision to pull out of the Mexican tournament last week came with the bookmakers already setting the odds for his intriguing first round clash against another big server in America's Frances Tiafoe, which was billed as an early drawcard clash in Acapulco.
Now South Africa's Anderson has been earmarked as a starter for what is another of his favourite tournaments, starting this week, the Masters 1000 Miami Open, which takes place close to where he resides as his home base in the United States.
And, unlike Doha and Acapulco, Anderson supporters will be holding thumbs for their man to make an appearance and prove that his "passion" for the game is still burning brightly and to good effect.
