In their first career meeting, Iga Swiatek scored a 6-1, 6-4 second-round win over Hsieh Su-wei at Roland Garros. But it turns out they have played together before, when Swiatek was a ball kid at the now-defunct Warsaw Open.

"Who would've thought that I already played doubles with one of the best doubles players in the world?" Swiatek wrote on Instagram when she first shared the insight earlier in September."10 years later we're on the same tour and I'm able to compete at this level on a daily basis."

After the win on Wednesday, Swiatek posted the picture again, stitched together with a similar shot from their Roland Garros match:


"No high five no kiss today. Merci," Hsieh wrote when she posted the picture herself.

"In the back of my mind I was a little bit worried, because she has a strange style of game," Swiatek said about her mindset before the match. "I have never played against her ... well, besides the match that we played when I was, like, 10 years old, we didn't play against each other."

Hsieh's crafty and unconventional game caused no issues for Swiatek, who won in just an hour and seven minutes.

On Friday, Swiatek dismissed Eugenie Bouchard to reach the fourth round for the second year in a row.
