He's said he will play according to Swiss-German sources (no more information in these then I will not say more).
From what I've seen the courts are different during the day and in the evening : they were very slow (and not high bouncing) yesterday evening (slower than in Monte-Carlo) because it was freezing, in the day they were like in Roma usually.
The bounce is lower in Roma than in Monte-Carlo and RG then it might help Fed.
Berlocq beat Kavcic 6-1 6-3 then he must be in-form, he's a grinder who plays with a lot of spin and a really good (one-handed) backhand.
If Fed had to meet him in R16, I saw Monfils last week against Kohlschreiber in a very good match : he looked in good form and very motivated to me.
A semifinal here would oblige Nadal to win the tournament to get the number 2 seed. If Fed loses earlier, a final would be enough for Nadal.
Anyway, the only purpose of getting the number 2 seed in RG is being certain to avoid Djokovic in the semi (but it would be the same chance to face Nadal in the semi), and having half-a-chance that Djokovic and Nadal meet in the semis, which would be a good chance to avoid Nadal in a potential final ... if Fed can reach there
