Heavy rain over Flushing Meadows shut the outside courts and left 14 first-round matches to be replayed into Wednesday, compressing a schedule that was already carrying a full first round across two days.
The matches that did finish were the ones under a roof. Madison Keys came through 7-5, 6-4 against Alina Korneeva — "it's so hard to play the first round of a Grand Slam," she said afterwards — and Flavio Cobolli, the fifth seed, lost the first two sets to Francisco Comesana before winning 3-6, 2-6, 6-3, 6-4, 6-4.
Alexandra Eala beat Mary Stoiana 6-1, 6-2, Coco Gauff beat Zeynep Sonmez 6-3, 6-4, Taylor Fritz beat Darwin Blanch 6-3, 6-2, 6-4, Elena Rybakina beat Thea Frodin 6-3, 6-2 and Mirra Andreeva beat Janice Tjen 6-2, 6-2.
