I think [this](https://github.com/BillPetti/baseballr/blob/master/R/mlb_pbp.R#L217) might be the source of the problem because some columns are being `tidyr::fill`'d up when they shouldn't be. For the one game I looked at (661400), `"matchup.postOnThird.id"`...

Putting on my maintainer hat for a second, it looks like that `dplyr::fill` has been there as far back as the commit history goes. It's not clear to me why...
