Manager Dave Martinez said depth catcher Welington Castillo was uncomfortable playing because he has young children. He joins first baseman Ryan Zimmerman and pitcher Joe Ross among those deciding not to play for the defending World Series champions.

The 33-year-old Castillo played last season for the Chicago White Sox and then joined the Nationals as a backup option.

Indians outfielder Delino DeShields Jr. has tested positive for the coronavirus and is being quarantined from his teammates.

Chris Antonetti, the team’s president of baseball operations, said DeShields tested positive before coming to Cleveland. The Indians held their first workout at Progressive Field on Friday.

Antonetti said DeShields is doing well and has only had “very mild symptoms” at this point. He’ll have to twice test negative before he’s permitted to re-join the ballclub.

The 27-year-old DeShields spent the past five seasons with Texas. He was acquired by the Indians in the offseason trade that sent two-time Cy Young Award winner Corey Kluber to the Rangers.

The Green Bay Packers are optimistic they will have fans at Lambeau Field this season, but they note that seating capacity would be cut significantly and spectators must wear face coverings.

The NFL club also acknowledges the “possibility that Lambeau Field will be unable to host fans for games this season" because of the pandemic. Training camps across the league are to begin in mid-July.

Reduced seating capacity means the Packers can’t guarantee that ticket holders in the general bowl and club seats will be able to reserve tickets. Season-ticket holders will be asked if they want to be part of a process allowing them a chance to reserve tickets.

Those who opt out can have their 2020 payment refunded in full or credited to 2021. If they opt out, their status as season-ticket holders and their existing seats and ticket packages will remain in place for next season.
