NEW YORK (Reuters) - Fearless Carlos Alcaraz would not be distracted by a Stefanos Tsitsipas mid-match bathroom break holding his focus to upset the Greek third seed 6-3 6-4 7-6 (2) 0-6 7-6 (5) on Friday and advancing to the fourth round of the U.S. Open.

Having assumed the role of villain at this year's U.S. Open over his lengthy well-timed trips to the washroom that have been criticized as strategic delay tactics, Tsitsipas threw everything he had at the 18-year-old Spaniard.
