A little after 6 p.m. on a breezy midweek summer evening in Vina del Mar, Chile, Rafael Nadal walked on to the clay court at the 2013 VTR Open after a seven-month injury absence that had many fearing for his career. The whirling click, click, click of cameras and shouts of "Rafa! Rafa!" echoed around the venue as the 11-time grand slam winner walked across the court tight lipped and unsmiling, waving half-heartedly at the crowd. Rolando Santos was there for CNN with his camera.
