I specialise in tennis and football writing at The Playoffs News, and I have prior experience working at EssentiallySports and Sportskeeda. Born and raised in Bengaluru, India, sport was my safe space right from my childhood. After trying my hand at multiple sports and representing my educational institutions in cricket, badminton and table tennis, I found sports media to be my calling. My message to the readers is not to be shy to express themselves - regardless of whether it is playing, talking or writing about sport. And if you\u2019re a fan of Roger Federer, Lionel Messi and\/or Stephen Curry - I\u2019m your guy. \u00a0","sameAs":["https:\/\/www.instagram.com\/sankalphk","https:\/\/www.linkedin.com\/in\/sankalp-hk-660254215"],"url":"https:\/\/theplayoffs.news\/en\/author\/sankalp\/"}]}},"_links":{"self":[{"href":"https:\/\/theplayoffs.news\/en\/wp-json\/wp\/v2\/posts\/627736"}],"collection":[{"href":"https:\/\/theplayoffs.news\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/theplayoffs.news\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/theplayoffs.news\/en\/wp-json\/wp\/v2\/users\/34"}],"replies":[{"embeddable":true,"href":"https:\/\/theplayoffs.news\/en\/wp-json\/wp\/v2\/comments?post=627736"}],"version-history":[{"count":7,"href":"https:\/\/theplayoffs.news\/en\/wp-json\/wp\/v2\/posts\/627736\/revisions"}],"predecessor-version":[{"id":628294,"href":"https:\/\/theplayoffs.news\/en\/wp-json\/wp\/v2\/posts\/627736\/revisions\/628294"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/theplayoffs.news\/en\/wp-json\/wp\/v2\/media\/627745"}],"wp:attachment":[{"href":"https:\/\/theplayoffs.news\/en\/wp-json\/wp\/v2\/media?parent=627736"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/theplayoffs.news\/en\/wp-json\/wp\/v2\/categories?post=627736"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/theplayoffs.news\/en\/wp-json\/wp\/v2\/tags?post=627736"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
