The San Francisco Giants, who play at Oracle Park, said in a statement that they would cancel their only event at the stadium during that city’s two-week ban on public gatherings — a March 24 exhibition against the Oakland Athletics.
Santa Clara County, where the N.H.L.’s San Jose Sharks and M.L.S.’s San Jose Earthquakes play, announced a ban earlier in the week on gatherings of more than 1,000 people. The N.H.L. said in a statement, after the N.B.A. suspended its season, that it was evaluating its own plans for the season. Earlier, the league said it was working with the Sharks “to determine an appropriate course of action for home games through the end of the month.”
In Washington State, Gov. Jay Inslee banned gatherings of more than 250 in multiple counties, including King County, which encompasses T-Mobile Park, the home stadium of the Seattle Mariners, and CenturyLink Field, where the Seattle Sounders FC of the M.L.S. play.
The Sounders said their March 21 match against FC Dallas, which was to take place at CenturyLink Field, would be postponed.
While many events in different industries have been canceled or changed because of the health crisis, attention sharply shifted to the sports world on Wednesday after Dr. Anthony S. Fauci, the director of the National Institute of Allergy and Infectious Diseases, put the sports leagues on notice in an appearance before lawmakers.
“We would recommend that there not be large crowds,” Dr. Fauci said. “If that means not having any people in the audience when the N.B.A. plays, so be it. But as a public health official, anything that has large crowds is something that would give a risk to spread.”
Still, the N.B.A. had seemed determined all day to carry on in some capacity.
In Washington, D.C., despite a recommendation from the Department of Health that large gatherings be postponed or canceled, Monumental Sports and Entertainment, the ownership group of the Washington Wizards and the N.H.L.’s Washington Capitals, said its home games would be played as scheduled “at the current direction” of both leagues.
