Cobb is close just behind Trout and Mays

I'm not sure baserunning has much value in a lineup with so many thumpers.

Bench and Schmidt might be the weakest runners and I don't think they'll gum up the base-paths.

Overall, I think you are correct that all of the lefties Ruth, Gehrig and Bons/Williams weren't hurt too much by lefties but only Bonds really ever saw the lefty relief specialist so splitting them up doesn't diminish the lineup much if at all. Leaving them in also doesn't hurt much even if the lefty specialist has a greater effect than a lefty starter.
