The Reds have improved the number of good relievers on the team. But, in making the final selections, I hope they realize the importance of guys who can pitch often, for more than one inning.
Weathers, Cordero, Burton, Stanton, Affeldt will likely be used for one inning at a time. I'm sure several of them can go more than one, but none of them fits the "workhorse" mode of an innings eater. (Burton might, but the Reds likely will use him as a late inning set up man. Affeldt was effective pitching short stints last year for the Rockies.)
Bray can be a multi-inning guy. I thought the Reds suffered last year because he wasn't around due to injury.
The remaining spot? I wouldn't mind if Coffey got a shot at it. He can pitch two innings and can do it often.
If Coffey and Bray are on their game, this will be enormously beneficial to the Reds. When a starter has to leave in the fifth or sixth, it's great if you can put in an effective reliever for two innings. Switching relievers every inning leads to a worn out bullpen.
I'd prefer this type of innings-eater over a sixth starter for long relief. The sixth starter usually doesn't get to pitch very often and is really an insurance policy. I'd rather have the insurance policy in AAA.
So, I'm rooting for Coffey to continue to pitch well and to get the last spot in the bullpen.
