The only reason why I can see Cilic entering this tournament is that he most likely needs match fitness to get himself match fit for the French Open. Hopefully he does well but as we have seen, he has been in poor form so far this year. This could be his best chance to find some form and win this tournament before the French Open so lets see how he goes.
Yes, this is also what I thought. I read reports that he is somewhat nursing some injury that's why his form is very poor to say the least this year, but entering this tournament will probably give him some confidence. He is currently playing Cuevas, and it was a tough battle, winning the first set 7-5 and leading the second 5-4 with Cuevas serving. Coric on the other hand already won his match in 3 sets against Haase, 6-3, 4-6, 6-4, he is the second rank in this tournament.
Hmm I guess Cilic still isn't fit as he ended up losing the match against Cuevas. I'm not sure if he will be right to go for the French Open which is a shame as he is a great player and we always like to see the great players playing in Grand Slam tournaments.
