Jessica Pegula's Coaches Both Once Stood Where She Does Now

Jessica Pegula's team in the coach's box is made up of two men who know that seat from experience: Mark Knowles and Mark Merklein. Before either one was coaching, both built their own careers as professional tennis players, competing on tour themselves. It's the kind of detail that matters to anyone who follows her matches closely — the guidance coming from courtside is from two people who have actually played the point, not just watched it.
