Sad to see @RafaelNadal go out with an injury like that. Did well to fight on through the pain but was clearly in much pain. He hates to retire but the wise long term decision to retire. #AusOpen

Shattered for @RafaelNadal hope it something he can get over quickly. @AustralianOpen

Sad and very unusual image. @RafaelNadal leaving the court without having finished the match. The 10 time RG champion has to retire against @cilic_marin. The Croatian is in the semis/Touché au haut de la cuisse Rafa a abandonné contre Marin #AusOpen
