Every time she has an ankle scare prior to or starting a slam, she has made the final of that said slam...
2017 (ankle roll in Rome F, makes RG F)
2018 (ankle roll in R1 AO, makes F)
2019 (ankle slip in Wimbledon R1, makes F)
Of course the bad news for her is she lost the final the two times it happened in the past, but who would have thought such a correlation would exist?
