The mystery behind Novak Djokovic’s struggle has been one of the biggest storylines of the 2018 season. An encouraging start at the Australian Open—following a six-month layoff with an elbow injury—disappeared with the need for a “small medical intervention” and back-to-back opening round losses in Indian Wells and Miami.
More troubling than the results was Djokovic’s performance under pressure in those matches. When nerves got the best of him at key junctures against Daniel Taro and Benoit Paire, it had a compounding effect. Either a self-flagellating streak or diminished mental and physical prowess saw him blithely accept losing circumstances when in years past he would have battled to the end.
