Naomi Osaka’s coaching experiment with Tomasz Wiktorowski is already showing promise. The four-time Grand Slam champion began her new partnership this week at the Omnium Banque Nationale in Montreal, and on Wednesday, photographer Jimmie48 captured a proud, smiling Wiktorowski as Osaka battled her way into the third round.

In her first tournament with the Polish strategist, previously known for guiding world No. 1 Iga Swiatek, Osaka delivered a thrilling second-round performance against a familiar foe: Liudmila Samsonova. The duo have been frequent adversaries on the WTA Tour recently, and this latest chapter marked their fifth clash in less than a year and a half.
