Young American Reilly Opelka spoke with Mike during a trip to NorCal back in 2018. A heck of a lot has changed since then. He'd just started his foray in to fashion, but he's now a force on the Tour, with a couple of ATP titles in his pocket, and one of the most feared serves in the sport.

We talked to him about his growing health concerns, how he's adjusting to them, and where the sport is after a difficult 2020.

Thoughts and concerns, as always, to patreon.com/behindtheracquetpod!
