MIAMI -- Marlins manager Don Mattingly, sidelined since he tested positive for COVID-19 on July 31, is expected to rejoin the team Friday.

Mattingly, who was vaccinated in mid-April, experienced mild symptoms. The last-place Marlins began a series at San Diego on Monday, and Mattingly, 60, plans to return to the dugout when they start a homestand Friday against the Chicago Cubs.

James Rowson has been the Marlins' acting manager in Mattingly's absence.

Mattingly was voted NL manager of the year in 2020 after he guided the Marlins to their first postseason appearance since 2003.
