I'm going with:
Sloane Stephens +152 vs. Guburuza - Stephens is 2-1 against Guburuza and won 2-0 against her in their only match on clay at the French Open in 2019.
Lorenzo Musetti +275 vs. Stan Wawrinka - OK, this one is a bit of a longer shot, but I'm going with the much lower ranked Italian (#249 vs. #17) who is almost half the age of Wawrinka. Musetti is 44-27 on the year and 11-5 on clay. Wawrinka is 15-3 on the year and 7-0 on clay on the year. Nonetheless, I'm going with Lorenzo in this match.
