Kyle Garlick, another unnamed Twins player and a team staff member tested positive in the two days before the postponements against the Angels, manager Rocco Baldelli said this weekend. Shortstop Andrelton Simmons already hadn’t made the trip to Anaheim after testing positive early in the week.

Garlick played in the Twins’ 10-3 loss to the Angels on Friday night. The Twins aren’t scheduled to visit Angel Stadium again this season, and the Angels play four games at Minnesota on July 22-25.

There have been six MLB games postponed this year because of the virus, including a season-opening, three-game series between the Nationals and Mets after Washington’s coronavirus concerns.
