TORONTO -- Red Sox lefty Drew Pomeranz, who has been in a fight to find his mechanics all season, has been moved to the bullpen, manager Alex Cora announced on Thursday.
Lefty Brian Johnson, who won both of his spot starts while filling in for injured ace Chris Sale, will stay in the rotation as the No. 5 starter at least until Eduardo Rodriguez (right ankle sprain) returns.
The Red Sox are playing a day-night doubleheader on Saturday in Baltimore, and there's a chance the second game could be a "bullpen" game involving Pomeranz.
