I suppose we do have to cut Alcaraz a bit of slack, he is still young, is #2 on the
ATP rankings and he has a long hard season with 6 tournament wins, probably
the same in quarter and semi final appearances.
Didn't expect that Alcaraz would loose, but as you say, it is not the end of the world. Even the greatest of all time do loose some matches so nothing unusual that Alcaraz looses a match here. In every sport upsets happen and sometimes you can make some good money out of it also
