Boggs started 2013 as the St. Louis Cardinals closer. After one month as the closer, he had two saves, two blown saves, two losses, a 12.66 ERA, and a ticket to Triple-A Memphis. He returned later in May, but after a third blown save, he was done in St. Louis. He was traded to Colorado for international signing bonus money. After some time in Colorado's minor league system, Boggs made nine appearances for the Colorado Rockies, but still walked five with five strikeouts in 8⅔ innings.
Overall, for his career, Boggs has a 4.12 ERA and 4.26 FIP. Walks have been an issue throughout his career, and he has 4.1 BB/9 for his career. In keeping with the Sox profile this offseason, he has a mid-90s sinker, a 90-ish slider, and mixes in split finger and four-seamer.
Currently, the 40-man roster is at 40, so somebody will have to come off the roster in order for the Sox to announce it. The unofficial terms:
Update: the move is official now. Boggs was added to the 40-man roster, and Deunte Heath was outrighted to AAA Charlotte.
