Giants broadcaster Jon Miller and wife Janine received good news from their doctors Thursday. Their tests for the coronavirus were negative.

The Millers’ son and his fiancee had tested positive for the coronavirus. They experienced symptoms several days after returning March 12 from Europe, where they got engaged, and had to wait until Saturday to be tested. Their results came Monday.

Jon and Janine Miller didn’t experience any symptoms but had been quarantining themselves. They got tested Friday, a day before the younger couple, but waited longer for the results.

Miller said he and his wife picked up their son and fiancee from the Phoenix airport March 12, the day Major League Baseball shut down spring training, and drove them home to Tucson.

The younger couple, before the symptoms, still took precautions with Jon and Janine, making sure they didn’t get hugs or touch any luggage.
