I have ruined the main thread by reading in comments and it is not possible to add comments to the main thread so here are the following player combinations in the following:
SEMIFINALISTS
1 Carlos Alcaraz vs 3 Danill Medvedev
2 Novak Djokovic vs Ben Shelton
There was a massive difference between the level of tennis played by the quarterfinalists in the Top Half of the Draw and the tennis played by the quarterfinalists in the Bottom Half of the Draws, The players like Medvedev and Alcaraz had to fight for points all the way and that was in particular by the commentator on the match between Medvedev and Rublev the interviewer after the match referred to the fact by thanking both Medvedev and Rublev for playing spectacular tennis.
That makes Alcaraz the favorite to win in the final, In that regard I think that in the unlikely event that Medvedev beats Alcaraz in the semifinal he will be favored to beat his opponent in the final.
