As the clock ticked past midnight into Thursday morning, Stan Wawrinka and Juan Martin del Potro were just starting the third set.<br />In the end, Wawrinka simply wore down del Potro, 7-6 (5), 4-6, 6-3, 6-2.<br />it was a crazy atmosphere, really late match.<br />Thank you everybody for staying so late.<br />I'm really happy to have won that match.<br />For del Potro, the outcome was a disappointment, but reaching the quarterfinals was another milestone in his return from recurring wrist injuries that had cost him most of three years on tour.
