Dave Stewart is down 15 pounds, and feeling “about eighty percent” healthy.

All of this part of an illness, which two weeks ago, the former pitcher-turned NBC Sports California A's analyst feared was coronavirus.

“I was very, very much afraid,” Stewart said, who also suffers from asthma.

The 63-year old’s symptoms began while on a baseball business trip in Monclova, Mexico. The return flight to California is when he knew something was wrong, and testing for COVID-19 was imminent.

“Went straight from the airport, to the testing place,” Stewart said. “They didn’t even give me two minutes, rushed me into the tent, put a mask on me. And started the testing.”

That testing, as you might well already know about, is invasive through the nasal cavities.

“Two swabs, up these big tunnels of mine,” Stewart said about the testing process. “They put those things up there, I felt like they were in my brain. One for the flu, the other for the virus.”

Stewart’s breathing and blood pressure were also observed, in addition to an X-ray of his chest region.

Eight painstaking days later, he received good news: Everything was negative.

But that didn’t stop Stewart from self-quarantining the moment he got home. And for good reason: He has a 93-year old mother and 102-year old step-father.

“If I’m carrying it, and I don’t know it, then I’m responsible for two very elderly people,” Stewart said.

“The people that I could touch, and possibly give this to, and possibly endanger their lives.”

The 1989 World Series MVP is set to resume his role on "A’s Pre and Postgame Live" once baseball resumes. Stewart also was set to have his jersey retired with the A’s on May 23. But that is now inevitably better suited for a later date.

“This is certainly something I can live with, that’s for sure,” Stewart said.
