Thornburg (shoulder) threw out to 90 feet Wednesday, Evan Drellich of CSN New England reports.

EDGE Analysis

Thornburg, who has been out the entire year with a shoulder impingement, was tossing out to 150 feet earlier in the year before being shut down when some symptoms returned. He resumed his throwing program earlier in the week and has stretched out to 90 feet, though the Red Sox will look to stretch him out to 150 feet again before his first bullpen session. Given his setback earlier in the year, the Sox will likely be patient with the southpaw.
