Dominic Thiem to miss the Cincinnati Open

Dominic Thiem is currently down with a respiratory illness and has withdrawn from next week's Cincinnati Open.

Thiem is yet to play a hardcourt tournament this year. After a disappointing start to his comeback, the Austrian gathered some momentum by doing well in a few clay events last month.

Thiem reached the quarterfinals at the Swedish Open and the Kitzbuhel Open. He then went a step further at the Swiss Open, where he made it to the semifinals.

The 28-year-old now plans to return to action at the Winston-Salem Open, which will be held from August 20-27.

Taylor Fritz eases past Andy Murray in first round of Canadian Open

Three-time Grand Slam champion Andy Murray was no match for Taylor Fritz in the first round of the Canadian Open. The American completely outplayed the former World No. 1 from start to finish.

Fritz was up 5-0 in the opening set before Murray managed a hold of serve. The 24-year-old closed out the set after that. The Brit improved slightly in the second set, but his opponent claimed the last four games of the match to win 6-1, 6-3.

This was Murray's first Canadian Open appearance since he won the title in 2015. He'll be aiming for a better showing at next week's Cincinnati Open.
