Rubin Statham’s story reads like a classic tennis hustle: a decade-plus on the road representing New Zealand in the Davis Cup, grinding out Challengers, then channeling all that lived pain (and string bills!) into a product players actually need. He retired in December and is now full-time at the helm of Pro Stringer - portable, pro-grade stringing machines you’ve likely seen popping up in player lounges and, yes, even on trains.
