The Red Sox optioned Crawford to Triple-A Worcester on Monday.
Summoned from Triple-A to make an emergency spot start after Nick Pivetta was moved to the COVID-19 injured list, Crawford struggled in his MLB debut Sunday against Cleveland, lasting only two innings while surrendering five runs on five hits and two walks. The Red Sox won't require a fifth starter again until Sept. 14, at which point Pivetta or Martin Perez could be ready to return from the COVID-19 IL to step into the rotation. With that in mind, Crawford will most likely remain at Triple-A for the rest of the season.
