Thiem beats Laaksonen and weather in Washington

Dominic Thiem

Top seed Dominic Thiem eased through to the third round of the Washington Open on a rain-soaked day on Tuesday.

Rain delayed the start of the Austrian’s match, but he didn’t let it affect him as he powered past his Swiss opponent Henri Laaksonen in straight sets, 6-3, 6-3.

Thiem’s first serve was flawless, the 23-year old dropping just one point on his first serve in his first outing since his fourth-round loss at Wimbledon to Tomas Berdych.

Home favourite and number eight seed Jack Sock also made it through to the last 16 after overcoming Romania’s Marius Copil in two tiebreaks.

Sock faces either compatriot Jared Donaldson or Australia’s Marc Polmans in the next round.

“He’s a very tricky player. He’s a tough opponent for sure, especially on a court like this,” Sock said about Copil.

“It’s a little bit quicker than last week, and he serves cannons. He’s got a great first serve, great second serve … He’s not an easy break at all. I’m definitely happy to get through in straights.”

Number 13 seed Juan Martin del Potro of Argentina defeated Lukas Lacko of Slovakia 7-5, 6-2 to make the Round of 16, as did Britain’s Kyle Edmund, who got the better of Hyeon Chung of South Korea 6-3, 6-1.

Italy’s Guido Pella pulled off a surprise, beating Germany’s 12th seed Mischa Zverev in three sets 7-6(5), 6-7(2), 6-3.

Japan’s Kei Nishikori needed two and a half hours to defeat American Donald Young 6-3, 4-6, 7-6 (5).
