Syndergaard (elbow) threw off a mound Monday and is expected to face hitters in the coming days, Deesha Thosar of the New York Daily News reports.
Syndergaard's recovery from Tommy John surgery was slowed in late August when he tested positive for COVID-19, but he's resumed throwing bullpens recently. The right-hander will take another step in his recovery when he faces hitters this week, and he'll likely have a better return timetable based on how he feels afterward.
