You are right, his first serve looks more like a second serve. I remember it being way better.Last time I saw Alcaraz was in Rio, so I was curious about this matchup and watched both of their QF. What happened to the Alcaraz serve now? He has very little pop on it and he's rolling it in. As he moves up, better players are going to feast on it but I could've sworn in Rio it was a bigger weapon. Musetti has the better serve but he is too passive, Alcaraz has the ability to dictate the points here with his forehand. If it weren't for his wimpy serve, I would tip the Spaniard but this looks to be 50/50.
