Jeff Savage first learned about COVID-19 in February, reading an email from a distributor of novelty rings in China. The note was confusing at first for the president of the Sacramento River Cats, the Triple A affiliate of the San Francisco Giants. It said the business had to temporarily close its warehouse to stop the spread of something called the novel coronavirus, which was sweeping across China, killing thousands of people and infecting tens of thousands more. Because of the shutdown, the email continued, the Triple A champions would not receive their 5,000 faux-platinum rings in time to give them to fans attending the April 14 home opener.
