Shriver agrees. Doubles has helped singles stars learn the ropes of high-stakes tennis for years. She cites Ashleigh Barty and Victoria Azarenka as prime examples and says that now, thanks to the pandemic, is a perfect time to embrace the discipline.
"I think doubles, there can be a lightness and a little more fun, which I think everybody right now needs to look at - the fun factor,” she said. “If they have a partnership that's working and there is some enjoyment, absolutely keep it going right now."
She adds that having experience at the business end of a Slam in doubles can only help Krejcikova.
"For a doubles player to be in the quarters, semis, finals of majors, even though the eyes aren't on doubles as much, to the athlete you gain a ton of experience,” she says. “People don't realise that. To the doubles player winning a Wimbledon, it gives you very similar feelings.”
For Krejcikova, the task is simple: just keep living the dream.
"My breakthrough was during the Roland-Garros, which is one of my favourite tournaments, and it's also the tournament where I won my first Grand Slam. Everything was perfect, and ever since the breakthrough to the top 100 I'm really just trying to enjoy because I kind of accomplished one of my biggest dreams,” she said earlier this season in Dubai. “Now I'm just really enjoying and just doing the best I can.”
