Two days after his second 11-earned run start of the season, the Boston Red Sox have placed right-hander Tanner Houck on the 15-day injured list with a flexor pronator strain, the team announced Wednesday. Righty Cooper Criswell was called up in a corresponding move. On Tuesday, manager Alex Cora said Houck would remain in the rotation "as of now."

The Boston Red Sox placed right-hander Tanner Houck on the 15-day injured list on Wednesday because of a right flexor pronator strain. The move is retroactive to Tuesday. In a corresponding move, the Red Sox recalled right-hander Cooper Criswell from Triple-A Worcester.

Tanner Houck has an 8.04 ERA through nine starts this year, and with rotation decisions looming, the Red Sox might need to pivot.
