BOSTON (CBS) -The Boston Red Sox have claimed right-hander Sandy Rosario off waivers for the second time this off-season, the team announced on Monday.

The 27-year-old Rosario was originally claimed by the Red Sox from the Miami Marlins in October, but was later designated for assignment to clear a roster spot for the Rule 5 Draft. He was later sent to Oakland in exchange for right-hander Graham Godfrey on November, only to be designated by the Athletics two days later.

Rosario sported a 1.04 ERA with 16 saves and 24 strikeouts over 25 relief appearances for Miami’s Triple-A affiliate in New Orleans in 2012. He appeared in four Major League games for the Marlins, allowing six runs over three innings of work.

During the offseason, Rosario has appeared in 12 games for Gigantes del Cibao in the Dominican Winter League.

With Monday’s acquisition of Rosario, the Red Sox now have 39 players on their 40-man roster.
