The Chicago Cubs claimed Rosario, a hard-throwing reliever who has changed teams four different times.
The Sox roster is now at 38.
The Sox have been trying to work out language (best guess is medical language) in Mike Napoliís contract the past few days in order to solidify a 3-year, $39 million deal. Shane Victorino reportedly had his physical today and could be introduced to Boston media Thursday. Thatís two spots. The Sox would then need one more to get Koji Uehara on the roster as well.
The 27-year-old Rosario has had quite a ride.
The Red Sox claimed him off waivers from Miami in October, designated him for assignment in November, worked out a deal with the Aís for right-hander Graham Godfrey when he didnít get through waivers and then got him back on waivers when the Aís couldnít fit him on their 40-man.
It seems everyone is trying to outright Rosario because he has a great arm, but there seems very little room on 40-man rosters these days.
