The 11 saves would be the fewest to lead the Rangers since Greg Harris had 11 in 1985. Eric Gagne had 12 in the first four months of the 2007 season before being traded to the Red Sox and ending up as the Rangers' leader.
Claudio didn't become the closer until the beginning of July. Even then the Rangers never really declared him the official ninth-inning guy, and it's unlikely that they'll go into the offseason assuming he will automatically be in that role next year.
The Rangers have much to do to fix their bullpen this winter and will consider all their options in the closer's role.
