It is a worry. I'm with Margaret in hoping that he's skip RG this year. Better safe than sorry, and that way he'll have many more chances at it in the future.
I'm glad you thought that looked like a mess, too! Obviously, Zverev will move, up, but it depends on what happens tomorrow. If he wins, he carries real momentum. If he loses, however, it think it could leave a scar on his belief. And he's got to feel like he's underachieving at Majors, because he has been.
@PhiEaglesfan712 above says he like Ruud and Zverev, and their odds aren't great, (per that list I posted.) The Zverev +1600 is ridiculous to me, even before the Rome results to date. I think you make a good argument for Alcaraz as the favorite, but even there, I wouldn't say by much. It will be interesting to see Novak in Geneva next week. And, obviously, the RG draw.
