It may well be that the US weather service downgraded Cyclone Ida to the level of stable Salzburg snowfall: If it is even a little wet, you cannot play matches on the outdoor courts of the National Tennis Center. Basta. It was like that on Friday in the qualifying finals, it will be like that on Wednesday (hopefully not).

Upset Alert: Stefanos Tsitsipas vs. the stopwatch (second match after one in the morning, Arthur Ashe Stadium)

So: If even a booth sermon like Andy Murray's doesn’t have any effect, and Stefanos Tsitsipas is still looking for a longer walk to the toilet, then you have to take your hat off to the stubbornness of the Greeks. By the way, Tsitsipas got help from Reilly Opelka, who said that, given the conditions on the court, changing clothes, including shoes and socks, could easily take eight to ten minutes. Will Stefanos manage the surprise and this time stay within a single-digit number of minutes? Our stopwatch is drawn.

Top secret game of the day: Andrea Petkovic vs. Garbine Muguruza (from 5 p.m. CEST, Louis Armstrong Stadium)

Petko likes Mugu. Because it is different, as Andrea Petkovic put it in her press conference after the opening win against Irina Camelia Begu. So the Spaniard wants to live somewhere in the forest on her own after her career. Andrea Petkovic could contribute to a few days off on Wednesday. Because: The Darmstadt resident is full of self-confidence. And the two players know each other inside out: at the beginning of the year in Australia, she and Muguruza belonged to the same cohort.

The German glasses: Kerber, Kohlschreiber, Gojowczyk, Koepfer for the third round

Angelique Kerber still has an unfinished business with Anhelina Kalinina from the French Open 2021 and will try to settle it on Louis Armstrong in the second match after one o'clock in the morning. Philipp Kohlschreiber would like to balance the eternal balance in the sixth duel with Pablo Andujar (5 p.m. CEST, Court 9), Dominik Koepfer will meet Daniil Medvedev for the second time after 2019 at the US Open (second match after 6 p.m. CEST, Louis Armstrong). And Peter Gojowczyk is by no means an outsider against Dusan Lajovic (5 p.m. CEST, Court 8).

Here is the schedule for the third day of the US Open 2021
