Kimbrel , last night, is an example of the bullpen dilemma. He gets the save and preserves the win which , of course, is the point. But he uses 31 pitches to do so, gives up 2 hits and a walk getting there. OK, so no one can be perfect all the time, but now he can't pitch again until tomorrow. All the Sox relievers tend to be somewhat effective, but ineffcient. A relievers single biggest skill must be the ability to throw a strike/near strike and force the batter to act. Even the best will make outs 60 to 70% of the time.
