OAKLAND, Calif. -- Oakland Athletics minor league manager Webster Garrison has resumed breathing completely on his own for the first time in more than three weeks and no longer requires a ventilator as he fights the coronavirus, his fiancee said Thursday.

Garrison, hospitalized in his home state of Louisiana, wasn't yet speaking when Nikki Trudeaux posted her latest update Thursday.

"Webster Garrison is off the ventilator," Trudeaux wrote. "He is still weak and can't say words. He's mumbling a little bit. That's expected with that tube down his throat for that length of time and also being on all those sedatives so long. However, being on a ventilator for three weeks and one day, he is now breathing 100% on his own and his oxygen saturation level is at 100%."

Trudeaux has been asking for nightly prayers and using the hash tag "WebbyStrong" as the 54-year-old former major leaguer fights COVID-19.

The A's haven't identified Garrison but released a a statement late last month that "a minor league staff member has tested positive for COVID-19 and is under hospital care."

Garrison managed the Class A Stockton Ports last season, and it was unclear where he would be this season. The ex-infielder played five games for the A's in 1996, never getting a hit in 10 plate appearances while drawing one walk. He is from Marrero, Louisiana.

Trudeaux said she also tested positive for COVID-19.

For most people, the new coronavirus causes mild or moderate symptoms, such as fever and cough that clear up in two to three weeks. Older adults and people with existing health problems can experience severe illness, including pneumonia and death.
