The Seattle Mariners have shut down their spring facility because of the coronavirus and have advised their players to view the coming weeks as though they are in offseason mode.

Before opting to close their facility in Arizona, the Mariners had planned to keep the facility open and work with players in small, staggered groups of 10 after Major League Baseball announced it was delaying the start of the season.

On Wednesday, the Cincinnati Reds, whose training facility is also in Arizona, said an employee who works year-round at the complex tested positive for COVID-19.
