The Red Sox transferred Houck (back) from the 15-day injured list to the 60-day IL on Sunday.

EDGE Analysis

The transaction clears a spot on the 40-man roster for first baseman Triston Casas, whose contract was selected from Triple-A Worcester on Sunday in a corresponding move. Houck is scheduled to undergo surgery next week to address a disc issue in his back and will miss the rest of the season.
