I’m sorry this took so long, but I just emerged from a park home run and run adjustment rabbit hole yesterday, and with that out of the way, I was able to get this year’s win shares up and running.

2019 PL pitching win shares leaders
As mentioned in the previous post, I’ve hit a snag in my post-season work. To fill in a little bit of that gap before the playoffs start on Saturday, I was curious about which players had the best offensive seasons in NPB this year.
To measure that in a fairly simple manner, I’m borrowing standard wOBA (weighted on-base average) from Tom Tango using the stolen base version.
Here are the leaders in the CL and PL. I’ve included how many road plate appearances each batter had and their road wOBA because some might think their numbers are the product of their home parks. I’ve limited it to players with a minimum of 450 plate appearances.
CL wOBA leaders
