According to MLB’s 2020 Operations Manual, when a player tests positive, they must be isolated away from the team and remain in daily contact with the team, and undergo follow up testing as necessary.

“As part of its COVID-19 Action Plan, the Club also must identify and inform the Joint Committee of one or more local health care facilities to which it will refer any Covered Individuals who test positive for COVID-19 for treatment if the circumstances warrant,” the Operations Manual says.
