The Red Sox have made the anticipated transfer of Justin Masterson from the 25-man roster to the 15-day disabled list, citing shoulder tendonitis as the reason for his decreased velocity in the early going. In a corresponding move, the Red Sox recalled Robbie Ross Jr. from Triple-A Pawtucket to serve out of the bullpen while giving knuckleballer Steven Wright the nod to start Sunday against the Mariners.
None of this comes as a particularly surprising move, but the move to start Wright (possibly for an extended period of time) is by far the biggest story here.
