For starters: when a crack M's analyst differs with us in a comment, we don't put it on the front page in a spirit of debate. What happens is that guys raise points that are so intriguing that we "elevate" the point, as they say in the corporate world.
Guys know they are free to come back at us. :- ) It's about baseball.

Q. Sweeney wouldn't be a very good candidate to platoon with a LH bat. He hits righties better than he hits lefties. For his career, even.
A. Good point that Sweeney isn't a classic platoon hitter right now, as Ken Griffey Jr. certainly is, for example.
But: Law of Gravity Corner time. There isn't any question that RH hitters have less time against RH pitchers. Sweeney's own career "sample" aside, there are 10 million historic MLB AB's that give us an axiom to work with here. :- )
A hitter's last quality AB's, before retirement, will be with the platoon advantage.
.................
It is reasonable to project Sweeney to hit RHP's well again in 2010 -- but if you're predicting that, notice that you are also concluding that Mike Sweeney is not yet experiencing a bat slowdown due to age. (This may be true.)
At 36, I'd like to give Sweeney the luxury of that extra moment against LHP's, but I could be wrong.
:daps:
.................
Also, Sweeney's reverse platoon split is gentle: 860 or so vs RHP's, 825 or so vs LHP's. You don't necessarily use Sweeney DH vs Jon Lester because it's to Sweeney's advantage. You use Sweeney DH vs Lester because it's to Ken Griffey Jr's advantage.
Still and all, if you see Sweeney as better vs RHP's still, then you move past the simple LHP/RHP splits and you get Earl Weaver on it. Sweeney gets in there based on injuries, specific pitcher-batter matchups etc.
The 9-to-make-5 Beane roster allows you to play different cards out of your hand each go. If it's LHP vs RH, fine.

Q. I think it's a given that the Mariners will go with 12 pitchers -- my impression is that every team does nowadays.
A. This is something I don't have the information to address. (Hopefully somebody does, and will.) Is that true, that all 30 MLB teams use 12 pitchers, every year?
I'd be pretty surprised if 11 was no longer feasible in the 21st century -- but then, in the 1970's, the first team to use 11 was a phenomenon to us kids. So I'm biased. (Earl Weaver frequently used 9, and sometimes used 8. Homo sapiens' arms have not evolved all that much since 1975.)
What brought this up, of course, was the Mariners having two of the most durable pitchers in recent ML history, Felix Hernandez and Cliff Lee:
- Lee: 231 IP last year
- Felix: 238 IP last year
- Workhorse starter: 200 IP
- Lee + Felix - Workhorse x2 = 69 IP
- David Aardsma IP: 71
- QED
Lee and Felix are subtracting 70 innings from your bullpen over and above what 200-IP (!) starters would absorb. See what I'm sayin'? ::pittslurredspeech:: Only one guy can pitch at a time, right?
Suppose they hadn't acquired Lee, and then the M's told you they were going with 13-14 pitchers. Same IP-per-man. Ludicrous to use 13 or 14 pitchers, right?
We're conditioned to think that 12 is the correct number of pitchers. Actually, even if 12 were "correct," which I highly doubt :- ) that number would still have to flex +/- 1 based on whether any team's rotation was using 50 more, or fewer, IP.
...............
If Lee and Felix are going to go 235 apiece, you'll be mismanaging your bullpen to have seven guys down there.
