NEW YORK (Reuters) - Fans and players will be expected to exercise caution despite COVID-19 restrictions being eased when the U.S. Open begins on Monday with capacity crowds in attendance, the United States Tennis Association (USTA) said.

A year ago the tournament barred fans from attending, while players faced possible fines and expulsion if they exited the tournament's "bubble" without written consent as they were kept largely sequestered from New York City in Long Island accommodations.
