Swiatek defended match points while being on serve, and played those points on her terms by dominaiting and sending winner/forcing UE so I don't know how can you call that lucky. Luck is when you defend match/set points while returning elite server who decides to miss 1st serve by an inch and then commit a tennis suicide like certain Swiss player for example.
@topic she is top1 player on clay, top1-2 player on hard courts but probably still outside top10 on grass so the sky is not falling by going out earlier lol. She will probably play 10-15 more wimbledons in her career so I give like 50% chance that she will win one someday.
