Cubs option RHP Justin Grimm to Triple-A Iowa, LHP Brian Matusz to start Sunday’s finale with the Mariners
The Cubs announced after Saturday’s loss to the Mariners that Justin Grimm was optioned to Triple-A Iowa to make room on the active roster for LHP Brian Matusz. The Cubs did not announce the corresponding roster move to add Matusz to the 40-mann roster.
Multiple reports prior to Saturday’s game indicated Brian Matusz would be called up to start Sunday’s game against the Mariners. The Cubs have been discussing using a six-man rotation and will implement the plan Sunday.
