HOUSTON -- For the second time in less than a week, the Astros on Saturday canceled their Summer Camp workout at Minute Maid Park after a staff member was potentially exposed to someone with the coronavirus, the team announced.

“As part of MLB’s testing and reporting plan, we were alerted that a staff member was potentially exposed to a COVID-positive individual outside the organization,” general manager James Click said in a statement. “Out of an abundance of caution, we have canceled today’s workout. We are working closely with MLB and our team physicians to follow the established testing and cleaning protocols so that we can safely bring our players and staff back to the field as soon as possible.”

The team’s alternate workout at the University of Houston, where about two dozen players in their 56-man pool are training, continued as scheduled Saturday.

On Monday, the Astros also canceled their workouts at Minute Maid Park and UH because of a delay in receiving the COVID-19 results from testing. The Astros began working out at both sites July 3, giving them three weeks to prepare for the July 24 season opener against the Mariners.

The Astros had some positive tests as the result of intake COVID-19 testing that was required prior to the start of camp. That was after the Astros had an unknown player test positive for the coronavirus in June. As part of MLB protocol, the players and field staff are having their temperatures checked twice per day while undergoing COVID-19 testing every two days.
