Will he just play on clay/grass this year? Looks like he is avoiding all hc tournaments.
I don't think he'll skip the US Open and the masters 1000 warm up tourneys. Also, of course the WTF if he qualifies.
Now, IW and Miami are another thing. Nadal will supposedly play 3 tournaments in 4 weeks in South America. When Acapulco ends he has like half a week until IW starts, and don't forget IW and Miami are back to back.
It wouldn't surprise me if he took a break and skipped these 2 to prepare for the proper clay season.
