Switzerland's Roger Federer defeated Peter Gojowczyk from Germany and qualified for the round of 16 of the Cincinnati Masters.
The Swiss won against the German 6-4, 6-4 in 72 minutes on Tuesday, reports Efe.
Federer, seven-time champion of the Cincinnati Masters, will now face Argentina's Leonardo Mayer, who knocked out Frenchman Lucas Pouille, 16th-seeded, 7-6 (7) and 6-4.
Mayer, 50th on the world's ranking and finalist of the Hamburg tournament in 2018, has never beat Federer before and even lost to him twice in the 2014 Masters 1000 tournament in Shanghai and the 2015 US Open.
