Stephanie Kovalchik and Graeme Spence—data scientists with the Game Insight Group (GIG), formed by Tennis Australia in partnership with Victoria University—join Thirty Love host Carl Bialik to break down Player DNA, their new system for analyzing what makes tennis players great.

Kovalchik and Spence explain why the time was right for this form of analysis, why Roger Federer can be fast without great foot speed, and how their new ways of measuring injury risks will make it into TV broadcasts during this year's Australian Open.
