The San Francisco Giants and San Diego Padres will play a doubleheader Sunday after it was determined that a Giants player received a false positive on a coronavirus test, Major League Baseball announced.

Games on Friday and Saturday were postponed following the positive test, the first postponements due to COVID-19 for both teams. There have been 45 major league games postponed this season because of coronavirus concerns.

“Following a careful review of all of the details presented in the particular case regarding a San Francisco Giants player that led to the postponements of their road games in San Diego on Friday and Saturday, the committee has determined that the presumptive positive did not represent an actual infection or present a risk to other personnel,” MLB said in a statement.

MLB did not say when the second game would be made up.

On Friday night, both teams lined up for a moment of silence for the victims of the Sept. 11, 2001, terrorist attacks and then the national anthem. But the Padres didn’t take the field and the team announced minutes before the scheduled first pitch that the game had been postponed.
