She turned heartbreak into triumph
In her final round of Wimbledon qualifying in Roehampton, Sierra led her opponent Talia Gibson 5-3 in the deciding set, and held match point, before she dropped four games in a row and lost the match.
As a candidate for a lucky loser spot, Sierra stuck around, hoping to still make her way into the main draw, but she never expected to get the call-up just 15 minutes before her first match against Olivia Gadecki on Monday.
“I was eating in the restaurant when I found out. I just changed, we talked five minutes and then I entered to the court. But it was good because I didn't think too much,” said Sierra.
The rest, as they say, is history.
Sierra knocked out world No.43 Katie Boulter in the second round to claim the second top-50 victory of her career – her first was over a then 32-ranked Emma Navarro at a WTA 125 in Florianopolis in 2023.
Her unexpected run to the Wimbledon last 16 meant she had to change her accommodation in London four different times. She has surprised herself with every round and this time has an apartment booked until Thursday, just to be safe.
