Lowest WHIP for middle relievers, 2005-2007
I see that David Riske got a nice fat contract from the Brewers and I was curious to see how he came out on this fairly arbitrary search for the best relievers from the last 3 years.
The criteria are at least 80% of games in relief, at least 100 IP total over those 3 seasons, and no more than 20 saves (to eliminate closers.) You'll notice that some players qualified with just 2 of those 3 seasons.
Here are all the guys meeting those criteria with WHIPs under 1.2:

Riske makes the list at #13, and he's definitely posted some good numbers. Frankly, I didn't realize just how well the late Josh Hancock would stand up to such a set of criteria, but he makes it too at #20.
Scott Linebrink squeaks in there too, although his numbers have been trending very badly over the last 2 seasons. I suspect that Chicago greatly overpaid for him, and time will tell.
By the way, I hear a lot of people ask why middle relief pitchers aren't better. The answer is pretty clear: if they were good, they'd eventually become either a closer or a starter, roles upon which more emphasis is placed. Middle relievers tend on average to be the worst major league pitchers, with numerous exceptions.

I wonder if there has ever been a list of 21 pitchers pulled from the P-I that had only 2 lefties.
December 6th, 2007 at 11:32 am
I guess this list is slightly biased against lefties because of the 100 IP requirement, since many lefties are used for fewer batters overall.

Hi Andy
I thought about that too, but I did a quick informal study of run of the mill lefty relievers; Orosco, Groom, Embree, Stanton, Villone, Rincon, Eure and they seemed to have no problem meeting the 100 IP threshold.

I duplicated your study and restricted it to lefties and found 34 qualifiers with the median WHIP being 1.409. Doing the same survey for righties gave me 102 qualifiers withe a medium of 1.368
Using the top 15th percentile cutoff I found the lefty cutoff to be 1.256, and the righty cut off to be 1.179
Using the top 85th percentile cutoff I found the lefty cutoff to be 1.563, and the righty cut off to be 1.521
I don't know waht to draw from this, perhaps the scarcity of lefties causes a manager to give chances to less effective left handers, or perhaps this simply reflects left-handers being at a platoon disadvantage more than right handers.
I guess that's a topic for another day.
