The San Francisco Giants say two more people with the team are positive for the coronavirus following intake testing.
The Giants did not specify whether the two are players, coaches or other staff.
Prospect Hunter Bishop and pitcher Luis Madero, in the 60-player pool, had already tested positive.
"The impacted individuals have been placed in self-isolation and will continue until MLB protocols for discontinuing isolation have been satisfied, including clearance by the Giants medical staff," the team said in a statement Monday. "Contract tracing for both was conducted and resources and protocols are in place to ensure these individuals receive the best medical care."
