Juan Martin del Potro gets the mover of the week honors; unfortunately for him, the Argentine was unable to defend his points from getting to the final of the US Open last year due to yet another surgery. However, as usual, he continues to have a positive attitude and is hoping to be back on tour soon. The Argentine has been missing from the tour since late June after re-injuring his right knee (had surgery on June 22nd). The last major of the season is over and some players who went deep in the draw benefitted by getting a boost in their rankings.
