My strong opinion is that Rafa should have played a warmup tournament on grass before W (Hale). big mistake.
He put himself in a jam, played too much so needed rest but also needed a warmup.
He could have played a few rounds and then tank, that may have worked.
Did he ever skip the warmup event before?
2007 he played Queens, reached the Final of W
2008 he played Queens, won W
2009 didn't play on grass at all
2010 he played Queens, won W
2011 he played Queens, reached the Final of W
2012 he played Hale, lost in R2 at W
2013 no warmup tournament, lost in R1 at W
so, you, see the pattern. every time he played a warmup tournament on grass (except last year), he reached the final or won Wimbledon (since 2007)
