The San Diego Padres and the San Francisco Giants have been idle since a positive COVID-19 test for a member of the Giants was reported on Friday. However, MLB has reportedly determined it was a false positive, based on extensive subsequent testing, and the teams are playing a doubleheader today.
There has been no announcement yet, it appears, on the rescheduling of the other game that was postponed between the teams (Friday and Saturday games were originally postponed), but the teams play each other in the final weekend of the season, so one would guess that a doubleheader would be played then.
