Red Sox outright Rusney Castillo to Triple-A

Red Sox outfielder Rusney Castillo was outrighted to Triple-A Pawtucket, as first reported by FanRag Sports’ Jon Heyman. Castillo has been removed from the team’s 40-man roster.

Castillo, 28, has struggled since signing a 7-year, $72.5 million contract with Boston in 2014. He was available to any team willing to pick up the remainder of his contract, though he went unclaimed and will now stick in the minor leagues for the foreseeable future.

Castillo has hit .262/.301/.379 with 7 home runs in 99 games with Boston over the past three years, though has hit just .245/.304/.320 with Pawtucket this season. With Jackie Bradley Jr., Mookie Betts, Brock Holt and Chris Young rounding out Boston’s outfield, there is no room for Castillo on the major-league roster.

Castillo’s return to the majors likely depends on his offensive performance with Pawtucket, as the Red Sox are unlikely to give up on their costly project so soon.
