Stephen Strasburg hasn't pitched in over a month and the Washington Nationals moved him to the 60-day injured list last week.
The right-hander is unlikely to return this season as he deals with a nerve issue.
The Nationals previously suggested they feared he's suffered a recurrence of the thoracic outlet syndrome that cut his 2021 campaign short.
Strasburg has been limited to eight appearances since the 2019 season ended.
