Retire?? Should't he just kill himself. You're sounding like TennisFanCroatia. Ivo's going to have a lot more sucky losses over his career, but he's going to mix in a lot of good wins too. It is time for him to have a descent run in a grand slam, actually it's past time!
Sorry but he improves in the rankings, but keeps sucking at grand slams. When he gets a chance like this he shouldn't blow it. I know he wouldn't retire but it would really be worrying considering Minar sucks big time, qualified here with losing a maximum of 3 sets that a player who qualifies can lose, and also he made only 3 CH quarterfinals this year, all of them were on clay and the last one was in April.
I know and I have always thought of Ivo as a player who can beat top players but can also lose to the relatively unknown ones but he has improved his game in the last years and should play good enough to beat players ranked at #302 like Minar or #434 like Gregorc.
Don't get me wrong, I support Ivo and always will but I just don't want him to waste another chance at a grand slam. We've had enough of this. He should make at least 3rd round and possibly 4th to play Rafa.
