Steven Finn is a triple Ashes winner. A 6"8 fast bowler with 257 international wickets to his name, he was part of a side that won Test series in Australia, India and South Africa. He got Steve Smith out twice in one game, and also counts Virat Kohli and AB de Villiers amongst his Test victims. Middlesex's youngest debutant at 16, he came of age bowling at Lord's, and would end his playing career at Sussex, 19 seasons later. Still only 36, he has already established himself as a voice on the BBC's Test Match Special and will be covering this winter's hotly anticipated Ashes series for TNT Sports. His new book, The Ashes Files, charts some of the highs and lows of his own time as a professional cricketer, and in this episode of 20 Questions With he explores the psychology of bowling, the thrill of success, the single-mindedness of his commitment to a sport he grew up playing, the challenges of balancing personal life with professionalism, the skillset required for his new roles in commentary and punditry, England's chances Down Under, and the importance of Ben Stokes to the project of winning back the urn.
