LONDON, Jan 10 (Reuters) - For every Jannik Sinner or Carlos Alcaraz, there are hundreds of professional tennis players doing the hard yards on the lower tours, scratching out a living before calling it a day.
Tunisia's Moez Echargui fits into that category. This time last year he was ranked just inside the top 500 and earned $2,160 for winning an ITF tournament in Monastir.
