At the start of the tournament, I picked Alcaraz to win it, so I'm obviously not changing horses now. I think he likely wins in three sets, four if he is a little slow getting up to speed in the first set.
Here's one big reason why I think Carlos will win. Ruud, if he wins tomorrow, will become #1 without having won a single 500 or 1000 level tournament. That’s an incredible statistic. I’ve felt for some time that Caspar has a tendency to disappear in big matches. So I looked at it a little further, and there is a clear trend regarding his final weekend matches.
Ruud has won nine 250 level tournaments, all on clay except for one hard court victory (San Diego, 2021). He has been in four other finals, only two of which have been 500 level or above, Miami and Roland Garros, both this year.
Feeling that that’s not very many quality finals to have played, I checked his stats. This is how he has fared in every 500, 1000 and Grand Slam tournament in which he has gotten to at least the quarterfinals, from the beginning of his career to the present. The pattern will be obvious.
Finals
Roland Garros (2022) lost to Nadal 3-6, 3-6, 0-6
Miami (2022) lost to Alcaraz 5-7, 4-6
Semifinals
Rio (2017) lost to PCB 6-2, 5-7, 0-6
Rome (2020) lost to Djokovic 5-7, 3-6
Hamburg (2020) lost to Rublev 4-6, 2-6
Monte Carlo (2021) lost to Rublev 3-6, 5-7
Madrid (2021) lost to Berrettini 4-6, 4-6
ATP Finals (2021) lost Medvedev 4-6, 2-6
Rome (2022) lost to Djokovic 4-6, 3-6
Hurkacz (2022) lost to Hurkacz 7-5, 3-6, 2-6
Quarterfinals
Toronto (2021) lost to Tsitsipas 1-6, 4-6
Cincinnati (2021) lost to Zverev 1-6, 3-6
Vienna (2021) lost to Sinner 5-7, 1-6
Paris (2021) lost to Zverev 5-7, 4-6
Barcelona (2022) lost to PCB 6-4, 6-7, 3-6
That's 15 important losses where Caspar has won a total of three sets. When Ruud loses late in a tournament, he doesn’t actually show up. Doubt this will change tomorrow if Carlos is physically fit and can apply pressure early.
