Monday's game between the Minnesota Twins and the Oakland Athletics has been postponed due to the COVID-19 outbreak in Minnesota, Oakland manager Bob Melvin said Sunday.

Monday's game could potentially be made up in a doubleheader on Tuesday, pending further testing. The decision comes less than 24 hours after MLB postponed the remainder of the weekend series between the Twins and the Los Angeles Angels after outfielder Kyle Garlick and an unnamed player tested positive for COVID-19 on Saturday.

The total number of Tier 1 team members who have tested positive this week in Minnesota has grown to four. A Twins staff member tested positive before Friday’s game, and shortstop Andrelton Simmons was placed on the COVID-19 list earlier in the week after his own positive test.

“None of this has gone to plan,” Twins manager Rocco Baldelli said. “It can happen. This is the reality that we live in, the unfortunate reality that we live in, but we’re going to go forward. We’re not going to go backwards. We’re not going to dwell. We need to know what the next step is, and, that way, we can go attack it and do the best that we can.”
