The Red Sox optioned Lars Anderson back to Triple A Pawtucket after the game Tuesday night. But GM Ben Cherington did not announce a corresponding move.
What seems likely is the Red Sox will add righthander Aaron Cook to the roster on Wednesday. Cook can opt out of his minor league contract otherwise and he has pitched well enough with Pawtucket (3-0, 1.89 ERA in five starts) to quickly catch on with another organization.
The delay could simply be opening a spot on the 40-man roster for Cook.
