And her ranking kept moving up, to No. 17 by the end of 2020, No. 4 to close 2021 and No. 2 thanks to her victory at Indian Wells, California, last month.
"It's been really cool to watch her grow," Osaka said. "For me, I think the most impressive thing is being able to string together these two (tournament) wins in a row.
While the last step up was hastened along by Barty's departure from the game — and decision to drop out of the rankings rather than remain at No. 1 as long as her points would allow — it was clearly a natural progression for Swiatek.
"Just watching your journey is really incredible," Osaka told Swiatek during the
trophy ceremony Saturday, "and I hope you continue having fun."
After a bit of down time in Florida, Swiatek said, she will head home to Warsaw, where she is sure to be feted as the first Polish tennis player — female or male — to get to No. 1.
