I will probably bet on both underdogs to take at least one set or over games.
just looking at chances, there is a much value in betting on Schwartzmann, much more than on Tsitsipas, since Djokovic win is around @1.35, which is a good value, maybe even better than something to put on Tsitsipas to win a set or two
but, when i call the form and my view, i think that Djokovic will be in the final for sure, cannot call which way will be to reach it, but he will not lose this semi-final, expect losing his leg or arm before that, so this would probably be my bet for tomorrow
regarding Nadal, his win is really low to bet on, and Schwartzmann is in good form, i do not think that he can tie two wins over Nadal in a row, but one never know, losing in Rome is something that is happening to Nadal (has 9 titles there, so lost almost 50% of all tournaments in Rome when entered a draw), but on RG he has only two upsets, one by Robin Soderling (in a match where Soderling played his career best tennis) and from Djokovic in 2015, but then Nadal was not up to his game that season due to many injuries
long story short, when Nadal reached semi-final, he always won RG, but traditions are there to be thrown away, since his first lost match was in 4th round, second in QF, third should be in semi-final
