Like I said before, there will be a spell in a match in which Alcaraz will struggle to return opponent's serve. Now in fairness, going 0 for 8 on BPs in two return games is mind crushing, so it is probably why he only won ONE game after those opportunities. But for now, if you are able to frustrate Alcaraz on his return game, then he will start feeling pressure on his own service game. While Alcaraz has a good serve (depending on the day, match and etc...), it can break down especially if Alcaraz is struggling on the return game.
