While the pitchers have worked a treat, getting the Negro League hitters where they should be has been a real struggle filled with loads of trial and far too much error. But finally I think we're on the right track and now we're seeing some really strong performances from a broad number of quality players, as you can see from the screenshot of the best NeL hitters by WAR for the season to date.
Still far from perfect but at least I believe things are headed in the right direction.
