SAN DIEGO (AP) Prized shortstop Fernando Tatis Jr. wore a facemask throughout the reboot of spring training Friday for the San Diego Padres, who reported that outfielder Tommy Pham tested positive for COVID-19 and is asymptomatic.

General manager A.J. Preller said another test is pending but didn't identify the player.

Preller said Pham has begun self-isolation. "He feels fine. As a staff we're following all the contact tracing protocols and all the MLB protocols in terms of when you have a positive test," he said.
