Glasnow (shoulder) will throw another bullpen session and then head out on a rehab assignment, likely beginning with Double-A Altoona, MLB.com's Adam Berry reports.
He threw a 50-pitch bullpen session Tuesday and everything went well, so Glasnow will continue with the recovery process. Assuming he throws another bullpen session sometime this week, he will likely begin a rehab assignment next week. Berry notes that it is unclear if Glasnow will return to the big league rotation when he is activated or if he will be optioned to Triple-A. According to Berry, Gerrit Cole, Jameson Taillon, Ivan Nova and Ryan Vogelsong have a firm hold on rotation spots, so Glasnow would need to replace Chad Kuhl if he is to jump back into the big league rotation.
