I think this is a good idea for a team like Tampa Bay that is well aware they aren't going anywhere this year. For us, however, the way CC is going about stretching out our star relievers , is the correct way to use a bullpen. I wonder why it hasn't caught on much sooner overall. You had an Andrew Miller, and he was "revolutionary". However Rollie Fingers and fellas on that level back in the 80's routinely worked 2-3 innings for saves. If I'm not mistaken Dennis Eckersley is the one who started to really shorten those appearances into more so the 9th inning. I really think as has been stated.... if you have reliever A who pitches 75 innings this year in say, 70 appearances and reliever B who pitches 100 innings in 55 appearances, reliever B will have less chance of injury even though he put in more innings. The whole warm up process puts wear and tear on the body as it is. So if he's doing that less, i think you can get more millage out of guys going forward. Just makes sense! Not sure why we ever got away from that original way bullpens were used.
