Rick Renteria is not with the White Sox:

Before the team began a three-game series against the Cleveland Indians, general manager Rick Hahn issued a statement saying Renteria woke up with a “slight cough and nasal congestion.” Monday night’s opener was later postponed due to bad weather. The teams will play a doubleheader Tuesday. 

Renteria, who has been with the White Sox since 2017, was taken to a Cleveland hospital for evaluation and tests. The team did not say if the 58-year-old Renteria was being tested for the coronavirus.

Whatever the ailment, I hope Renteria gets well soon.
