Marin Čilić is the first player to qualify for the quarterfinals of 25. Vegeta Croatia Open, where he plays as the third seed. After only an hour and 7 minutes, Čilić defeated Igor Sijsling from Netherlands 7:5, 6:3. The match could have been even shorter, had Čilić seized the opportunity to win the set at 5:3 with his serve. However, Sijsling managed to take his serve, but Čilić returned the favor at 5:5. The second set ended without many surprises and ended in Čilić's victory. It was their fourth match thus far and each of them ended in Čilić's favor. "It was a bit of a strange match, but I think I served really well and it gave me two, three points per game", said Čilić after the match.

In the quarterfinals he will face the Czech Lukas Rosol, who chases each ball and always takes risks. They have played three times thus far, never on clay, and Rosol lost each time. "I have to let him make some more mistakes and concentrate on my serve", is Čilić's tactic for the quarterfinals.

The second couple of quarterfinalists in the lower part of the draw are Spaniards Tommy Robredo and Pablo Carreno Busta.
