Castillo (thumb) remains sidelined and is considered unlikely to return to Arizona Fall League action, WEEI.com reports.
Analysis:The report also notes that Castillo may not play in the Puerto Rico Winter League, though the Red Sox have not made a final decision on that front. It seems the team is largely concerned with protecting its $72.5 million investment, as Castillo is believed to just be dealing with a bruised hand and thumb, with nothing more than rest prescribed to treat the ailments. Castillo has hit .278/.333/.361 with three doubles, three walks and six strikeouts in 39 plate appearances in the AFL thus far.
