Carl Bialik rejoins the podcast to talk about player #127 on the Tennis 128, Stan Wawrinka. We consider how he improved so late in his career, what role Magnus Norman played in the transformation, how he might have fared in other eras, and much more. We start by recapping some highlights from the Australian Open, particularly the domination of Ashleigh Barty and the difficulty of forecasting a return to form such as the one we saw from Rafael Nadal. If you've had enough Australian Open talk by now, skip to start of the Wawrinka discussion at 28:15.
