Si allunga a sette la striscia di vittorie consecutive di Juan Martin Del Potro che, dopo aver trionfato a Stoccolma, ha conquistato un posto nei quarti di finale anche agli Swiss Indoors di Basilea. L'argentino, numero 42 del ranking ATP ma inserito nel tabellone renano grazie ad una wild card, si è sbarazzato in due set di David Goffin (ATP 11), testa di serie numero 5 del torneo, chiudendo sul punteggio di 7-5 6-3.
Dopo un primo set equilibrato, deciso soltanto con un break all'ultima occasione possibile, il sudamericano ha accelerato nel secondo parziale, sfruttando al meglio un passaggio a vuoto del belga nel quarto gioco, in cui ha commesso ben due doppi falli. Ora per Delpo - che si è così preso la rivincita su Goffin, impostosi due settimane fa nel primo turno di Shanghai - si prospetta una sfida di altissimo livello contro il quinto giocatore al mondo, il giapponese Kei Nishikori, reduce da un bronzo olimpico e dalle semifinali agli US Open.
Hanno staccato un biglietto per i quarti di Basilea in questa giornata anche il lussemburghese Gilles Muller (37), lo spagnolo Marcel Granollers-Pujol (39) e il croato Marin Cilic (12).
