Lefty vs. righty leagues experiment

1) One league is all lefty pitchers vs. whatever hitter you choose (usually, but not always, righties):

League-wide, that's a 1,003 OBP and 7.81 ERA

2) Second league is all righty pitchers and lefty and switch-hitters:

League-wide, that's a .806 OBP and 4.95 ERA

I know, we already understand that more righty hitters kill lefty pitching than vice versa, but just in case you needed data....I did notice a ballpark effect, where owners used more bomber parks in the 1st league and more pitcher parks in the 2nd league. Both are $140M leagues.

cool stuff

I think the biggest reason is the predominance of righties among the stud pitchers. Using Diamond Dope BR stats in Fulton Co Stadium:

- 24 of the top 30 SP* are RH
- 54 of the top 70 SP* are RH
- 15 of the top 17 R(1) are RH
- 31 of the top 40 all other exclusive relievers (R2-R5) are RH

Using only lefty pitchers eliminates ~ 70-75% of the pitching pool, and most of the top end guys. If you reran the righties league and eliminated all RH SP above 10M and all RH RP above 5M to level off the pitching gap, I bethe OPS would be almost equal.

Jeff Bagwell has 46 homers and 103 RBIs --- in 57 games!

Man such a great card...but in that environment...whew!

The lefty pitcher situation with TSN/SOM online always was unsatisfying for me. I realize it is a statistical reality, but lefties are definitely more easily handled due to the value of lefty killers in the pricing model due to the splits assumption.

Because in real life, I always wanted to be a southpaw because it at least appeared to yield an advantage, and my kids too--baseball and tennis.
Nothing like a lefty to mash things up.

Maybe an actual higher level pitcher like Matt could expand, but to catch scout's eyes as a RHP, with few exceptions, you used to have to be larger than the average lefty and be able to peak in the 90s. Otherwise, you'd have to post stats consistently until they couldn't ignore you.

For LHPs, much more latitude on size and speed for scouts.

Today of course, the game is much different, as power reigns no matter what or how you throw.

Could you RE-run the experiment with everybody using the same ballpark?
We should have a cash slush fund to pay for fun experiments like this.
