Less than 24 hours after she claimed her first singles Grand Slam title, Krejcikova became the first woman since Mary Pierce in 2000 to lift both trophies at the clay-court major.
“Right now after all of this happened, this last two weeks, last two days, I feel really relieved and relaxed,” Krejcikova said.
Krejcikova and Siniakova are both 25 but have extensive experience playing together, having started their partnership in the juniors in 2013.
