Stefanos Tsitsipas’s climb up the tennis rankings over the past year — from 161st to 15th — could have been a blur. Fortunately for him, he has a high-definition record of almost all of it.

At the United States Open last year, Tsitsipas started experimenting with creating video diaries, a log of his travels in which he shares his delight at the various places and cultures he has encountered on the pro tennis tour. While some players rarely veer from a path between their hotel and the courts each week, Tsitsipas frequently struck out on his own with his camera, exploring as much as he could.

A year later, the results of his work — month after month of new cities and new experiences — are documented fastidiously on his YouTube channel, on which the 20-year-old Tsitsipas is the star, writer, director, cameraman, editor and graphics engineer.

“Tennis players, we’re traveling all year long, away from our home, and it’s not easy,” he said. “So we carry certain things with us on the tour which help us stay happy, stay motivated. Tennis is always going to be there. The traveling is always going to be there. So why not have a hobby and travel with it, and feel happy with it?”
