Bernard Tomic suffered something of a humiliation on a day of shocks in Houston.
The Australian was badly out of sorts as he fell to an absolutely dismal 6-1, 6-2 defeat to Marcel Granollers in just 47 minutes.
Tomic attempted to rally at the start of the second set, but was unable to convert any of his three break points before collapsing to defeat.
It was far from the only shock of the day. though. Fourth seed Reilly Opelka was dismissed 4-6, 6-4, 6-6 by young Norwegian Casper Ruud.
Oeplka’s fellow American Ryan Harrison had no luck either, falling to Swiss qualifier Henri Laaksonen 6-4, 7-5.
Even second seed Jeremy Chardy crashed out, although at least not without an almighty fight.
The Frenchman lost a marathon 185-minute match – the longest in the tournament’s history – 3-6, 7-6 (7-4), 7-6 (9-7) to Chile’s Christian Garin.
