South African Wayne Ferreira won more than 500 matches during a pro career that spanned from 1989 to 2005 and saw him rise as high as world No. 6.

Ferreira posted six victories over 14-time Slam champ Pete Sampras in his prime, including four straight between 1995 and 1998, when the American was in the midst of his record stretch as the year-end No. 1.

Ferreira had a little iron man in him too, having set the all-time mark for the most consecutive Grand Slam appearances in men’s tennis. He played in 56 straight majors, surpassing the previous record of 54 held by Swede Stefan Edberg. 

But Ferreria, now 50, may have found his true calling in his role as a coach, as a mentor to American Frances Tiafoe and in this wide-ranging discussion with ATP Podcast reporter Jill Craybas, Ferriera speaks about his career and what he's learnt along the way that now helps his young player.
