@brokenshoelace : I'm just getting to watch the 2nd half of the match. You're a tough critic of Rafa. What was some of that slop about today?
I've only seen the highlights so far, haven't seen the match. It's tough to judge slop by the highlights as they don't show errors. My observation, purely based on the highlights (they were extended, but still) and the last couple of tournaments, is Nadal isn't hitting the ball particularly well, and his forehand has been a little off. The ability to change direction isn't there yet, and that always gives him confidence issues to pull the trigger. I think his serve is glaringly harmless, and that is a bigger issue to mean (as I think he'll get the forehand sorted out come RG).
The good news is he's moving very well and the backhand has been pretty good. I'm also usually harsh on his volleys but they were great today. I wouldn't be too worried about the French Open. I think he'll find his game when he's there. The conditions just suit him. The players I would "worry" about are Djokovic and Thiem, in that order, although the former way more than the latter. I actually think Rafa would hammer Zverev at RG if they were to play. A red hot Del Potro could be interesting but that's a big if anyway, and maybe a red hot Cilic, but that's pushing it.
