text: Murrayball Audiobook | Hugh MacDonald | Audible.co.uk
  Veteran sports writer Hugh MacDonald's lively Scottish brogue is the perfect complement to his long-form essay about rising Scottish tennis star Andy Murray. MacDonald explores Murray's obsession with self-improvement, in particular his commitment to marginal gains, the process by which athletes make small improvements in many different areas to close the gap on rivals. MacDonald's enthusiasm for his subject is contagious, and tennis fans will especially appreciate the information MacDonald shares about the diet, psychology, and training behind Murray's efforts to extract the most from his natural talent.
