During the Miami final one of the commentators said something I never thought I would ever hear: "... maybe Nadal needs to shorten the rallies..." At the height of their great rivalry, to be honest, Rodge never pushed him around so much as the king of clay would need to bend down and catch his breath. Actually, I had seen him do so only once before, at USO semifinal against Murray. Djoker defensive skills combined with Nadal's high margin counter punching produces some of the longest rallies in today's game. Nadal has not been able to penetrate Djoker's BH with his top spin. Actually, if you watched Miami final you would notice that it was Djoker who pummeled Nadal's BH and forced many unforced errors, usually a weak slice by Nadal that dropped in the net. Djoker is no dummy on clay either. Remember Madrid 2009? I believe Djoker's withdrawal from MC is strategic and preventive. He has no serious injuries, yet, but if these two new rivals keep clashing like they did at the last two tournaments this can give other players an opening later in this season. If it does, players such as Murray, Del Potro and even Sod better be ready.
