The Philadelphia Phillies shut their spring complex after five players tested positive for COVID-19 and at least three other teams closed camps Friday, raising the possibility the coronavirus pandemic could scuttle all attempts at a Major League Baseball season. The Toronto Blue Jays shuttered their site in Dunedin, Florida - about five miles from the Phillies' camp in Clearwater - after a player showed symptoms consistent with the virus. The San Francisco Giants' facility in Scottsdale, Arizona, was shut after one person who had been to the site and one family member exhibited symptoms Thursday.
