PHOTOS: The many expressions of Nadal, Thiem during their thrilling US Open quarters

What a showdown it was! No 'quarter' given by either player but eventually it was down to the one who craved it more, the one who fought that little point percent more than the other.

And eventually, it was defending champion Rafael Nadal who narrowly beat the young -- the one labelled his successor -- Dominic Thiem. Nadal won 0-6, 6-4, 7-5, 6-7 (4/7), 7-6 (7/5) to reach the semi-finals for the seventh time.

Isner changed 11 shirts, lost around 4 kgs in his US Open quarters!

It was a battle of wills out on court at the USTA Billie Jean King National Tennis Center on Tuesday, with the proceeding stretching to nearly 5 hours -- four hours and 50 minutes precisely.

There was sweat, frustration, some beautiful points won and a 'bagel' (against Nadal!). The emotions ran high as the match played out and here is a look at both players putting all their emotions on full display...
