With an illustrious career marked by 26 Grand Slam titles, there is no question John Newcombe is a tennis legend. But what doesn’t appear on the stat sheet is what separates the Hall of Famer in a league of his own in his native Australia – and the sport of tennis as a whole.     In the season finale, John emphasizes the importance of prioritizing self-analysis, visualization and mental fortitude — all in an era prior to sports psychology’s normalcy. The pioneer, who turned his practices into the acclaimed book, “The Power Within: How to create a high performance mind” speaks to how his mindset translated towards his tennis game, Aussie comradery, and prioritizing family while on tour around the globe.    John Newcombe captured seven major singles titles in 10 opportunities, all of which on grass. Collectively he claimed 34 singles titles and 33 doubles championships, allowing him to become one of the few players to hold the world No. 1 ranking in both singles, (1967, 1970, 1971) and doubles, (1965). John also aided Australia to five Davis Cups prior to being named the Australia’s Davis Cup captain from 1995 to 2000 – where he led the team to a 1999 title after a 13-year drought.     For more information on the TennisWorthy podcast and full episode transcriptions, visit tennisfame.com/podcast.
