Sorry folks, and by that I mean the bookmakers, but strap in, because I'm about to flip the script on this one. Welcome to the Croatia Open, where we live by one rule, seedings don't grant you divine rights.

Now, let's dig our heels into this spicy Round of 16 matchup. On one side of the net, our Tournament Seed 3, Camilo Ugo Carabelli. Now, Carabelli seems to be having a sort of love-hate relationship with his tennis racket recently. Yes, he's bagged some solid victories here, peeling off Mišolić, Van De Zandschulp, and Garín like they're ripe bananas, but let's not get too carried away. He also folded faster than a cheap lawn chair against De Jong J. and Giron M, wondering whether he was there for a tennis match or a philosophy lecture. You never quite know which Carabelli you're going to get.

Now, on the other corner, we have our underdog - or should I say underwolf? Francesco Passaro. The man who has clearly never heard the phrase "unseeded". He might have dropped the ball against Kym J., but let's not forget about his victories over Dodig, Rinderknech, Bueno, and Brunold. Passaro may not have a seed next to his name but recent performances say he's blossoming just fine, thank you very much.

So, while Carabelli is busy writing sonnets to his racket, it might be our unseeded hero who walks away with the big cheese. Strap yourselves in, folks. This one will be worth every bead of sweat dropped.

Albert's Prediction: Passaro in 3 sets.
