Players from the Philippines and Hong Kong will be on the schedule for the second round of a Grand Slam for the first time this week, as the U.S. Open sees the impact of an increasingly global game.

Alexandra Eala beat 14th seed Clara Tauson to secure the Philippines' first major match win on Sunday while qualifier Coleman Wong carried the flag for Hong Kong when he beat Aleksandar Kovacevic 6-4, 7-5, 7-6 (4) on Monday.

Renata Zarazua added to the global appeal as she became the first Mexican player to beat a top-10 opponent at Flushing Meadows with a stunning upset over sixth seed Madison Keys.
