Sept 4 (Reuters) - Round-up of day eight at the U.S. Open championships on Monday:
QUOTE OF THE DAY: “It’s just really nice to see him back, playing these kind of matches. That’s what he came back for. To get the crowd support the way he got it... we could even hear it on centre court. That’s the first time I experienced that.” -Swiss Roger Federer on his quarter-final opponent Juan Martin del Potro and the raucous crowd backing the Argentine got in his match against Dominic Thiem on Monday.
