He's not supposed to beat everyone, he'supposed to beat Hanescu... The rest of his draw is irrelevent since he couldn't get out of the first round.
As for Mareilles, no it's not going to get better. Hanescu didn't even get into the tournament in Marseilles, he's first in the alternate list. Though I think there is a player in the Marseilles entry list that is actually worse than Hanescu with Bautista-Agut, so I guess there is still a small chance that Janowicz could get a better draw there...
I believe actual Bautista-Agut is like >> Hanescu, especially after the AO i have a different appreciation of the guy
At that level, on indoors hard it's hard for me to figure a better draw than Victor Hanescu, he's not like terrible, but it's the kind of guy you want in a first round. Better than any qualifier and better than most players eligible for this level of tennis.
Maybe Ramos or Andujar, but again i'm not sure they're a better draw, rather an equally good one.
