Cresce il gioco di Roger Federer di partita in partita. Il basilese dopo aver battuto Diego Schwartzman (ATP 26), ha eliminato anche l'ucraino Alexandr Dolgopolov (41) al Masters 1000 di Shanghai, ottenendo così il passaggio ai quarti di finale. Il numero due al mondo ha cercato di essere il più sbrigativo possibile, spingendo al massimo sul servizio e limitando al minimo gli sforzi. E così in un'ora scarsa l'elvetico si è imposto per 6-4 6-2 e ora affronterà il francese Richard Gasquet (31), che ha battuto il connazionale Gilles Simon (47) 7-5 6-7 (5/7) 6-3.
Un'operazione riuscita alla grande nel primo set, concluso in soli 26 minuti con un break in entrata. Nella seconda frazione "Dolgo" ha provato ad opporre maggiore resistenza, ma il renano ha continuato a servire con un 80% di prime: cosa che non ha lasciato minimo scampo all'avversario.
