Alcaraz's issue was that he underperformed at the other two slams, and even in masters, outside of winning IW, I believe he didn't make a single masters final. Lost semi in Miami, basically was absent on clay masters with an early loss to Rublev in Madrid, didn't play Canada, lost early in Cincy to Monfils, lost early in Shanghai, lost early in Paris. The slam wins will only get you so far, also no points for Olympics. Even at Wimbledon, he couldn't gain any more points, he could only defend them.
What do you mean that with the victory at Wimbledon he only defended the points from the previous year?
The ranking at the end of the season is based on the points scored during the calendar year, so the question of points he had to defend at Wimbledon goes beyond all this, ergo, it does not justify anything of his eventual third place finish.
However, it is clear that Alcaraz's season was missed by the RG-WB double, if you win two slams the season is positive regardless of status.
The problem is that as I said some time ago, compared to 2023, the Spaniard, I won't say he has deteriorated but he certainly hasn't become a better player in 2024.
Too many unacceptable defeats against opponents who on paper he should beat rather easily.
As well as a performance that to define as fluctuating is an understatement, bad in the two slams that he didn't win also due to the way he went out, and his overall performance in the masters 1000 was very bad.
Apart from the 2 slams and the Olympic silver, the other thing to save from this season is the 3-0 record (for now) against the true dominator of the circuit in 2024.
As for Zverev, I read that some are calling his 2024 season his second best season if not even his best.
Absolutely not better, even if he were to win Bercy and the ATP Finals, his best season would remain 2021, where he won the 1000 in Madrid, semi-final at the RG, Olympic gold in the singles, victory in Cincinnati, semi-final at the US Open, victory in Vienna and at the ATP Finals.
