Daniil Medvedev's Rome Open title defence came to an end at the last-16 stage on Tuesday after the world No 4 was knocked out in straight sets by Tommy Paul, 6-1, 6-4.
Second seed Medvedev has never successfully defended an ATP Tour crown and was well below his best, stunned by American Paul who claimed his first win against the former US Open champion.

Paul will play Hubert Hurkacz, who knocked out Rafael Nadal earlier in the tournament, in the quarterfinals.
Medvedev, 28, had a great chance at the Foro Italico after a raft of stars either withdrew or were eliminated early, but instead, he became the latest big name to be dumped out of the last major tournament before this month's French Open.
Rome is missing the world's top four ranked men after Novak Djokovic's exit on Sunday and Italian world No 2 Jannik Sinner and third-ranked Carlos Alcaraz both dropped out injured before the tournament.
Holger Rune, who lost last year's final to Medvedev, and Madrid champion Andrey Rublev – ranked sixth in the world – and beaten finalist Felix Auger-Aliassime also fell on Saturday.
Hoping to pounce is world No 5 and 2017 Rome champion Alexander Zverev after sweeping past unseeded Nuno Borges 6-2, 7-5 to set up a quarterfinal clash with Taylor Fritz.
Later on centre court, reigning Monte Carlo champion Stefanos Tsitsipas takes on Australia's Alex de Minaur.
