The Astros announced Friday that McCullers (shoulder) began a throwing progression, Chandler Rome of The Athletic reports.
After landing on the injured list May 19 due to right shoulder inflammation, McCullers was shut down from activity for about a week and a half before being cleared to begin ramping up again. While McCullers doesn't necessarily appear to be headed for a long-term absence, the Astros could elect to have him build up slowly as a means of buying time to decide on what his role will look like moving forward. With Hunter Brown (shoulder) tracking toward a mid-June return from the IL and with Peter Lambert and Kai-Wei Teng emerging as viable back-end starting options, the Astros may not be willing to reopen a rotation spot for McCullers once he's ready for activation. McCullers struggled mightily over his eight starts prior to landing on the shelf, posting a 6.86 ERA and 1.53 WHIP across 39.1 innings.
