Both world No. 1s were among a slew of current top players and tennis legends who took to social media to celebrate the 20-time Grand Slam champion.

Among them: she’s now won her last 10 matches in a row against Top 10 players, and her last 10 finals in a row, too.

From Rafael Nadal to Iga Swiatek, the game's brightest lights paid tribute to the 20-time Grand Slam champion in the wake of his shock retirement announcement.

The Pole had her champion portraits done at the Top of the Rock, while the Spaniard was sent to Times Square for his photo op.

The only other woman in the Open Era to achieve the feat was Lindsay Davenport.

The world No. 1 discovered victory is indeed sweet after capturing her third Grand Slam trophy —and first in Flushing Meadows.

The beaten US Open finalist affirmed her desire to wrest world No. 1 from Swiatek while making a joking suggestion of a peace offering in the meantime.

“It’s also like a confirmation for me that the sky is the limit,” the 21-year-old said Saturday after defeating Ons Jabeur, 6-2, 7-6 (5).

While it'll be difficult to replicate Swiatek's spins or Jabeur's variety on the club level, check out some key tips that can get you playing like the Flushing Meadows finalists.

Swiatek won her 10th straight final and won her second major of the season, dispatching the Wimbledon runner-up in straight sets.
