Rennae Stubbs congratulated Coco Gauff on becoming world number one calling it a great thing that predominantly singles players are opting to play doubles more often.
Back in the day, many of the top players in the world used to play doubles consistently as Martina Navratilova proves with her incredible stats. In the newer times, singles players usually stayed away from the doubles playing singles exclusively. Trends are seemingly changing a bit again with singles players starting to play doubles again.
Coco Gauff is one noted singles player that is playing a lot of doubles tennis and with the recent doubles trophy in Montreal, Gauff become the doubles number one in the world. Former player Rennae Stubbs congratulated both her and Pegula on social media:
"Huge congrats to Coco Gauff for becoming the world #1 doubles player. It's so great to see some of the world best singles players battling it out for doubles titles. Big congrats to JL Pegula, the #1 ranked American singles player winning another dubs tourney too. Congrats ladies."
