Anyone can take over all other participants of a marathon by sprinting at the start line, but is sure not to achieve a great result at the finish line by doing so. Wonder if anyone else has the impression that Nadal is trying to sprint on his career, when maybe he should drop a little pace? First his foot injury, now the shoulder. Are those signs he is getting tired with playing so intensively in every match? PS. I'm not a Nadal hater, just curious of your opinions.
