It would be great if that P/G calculation also worked when you filter v. L and v. R. For the Chrome extension, it doesn’t work because the game denominator seems to pull every game in which a batter faced a lefty or a righty. So, summing the v. L and v. R games gives more than the total games played. It should probably filter based upon the starting pitcher in that game. Not a perfect proxy for actual P/G v. L and v. R but better than you get currently. For example from the Chrome extension:
All: 126 G, 897.1 P, 7.12 P/G
v. R 116 G, 628.2 P, 5.4 P/G
v. L 84 G, 268.9 P, 3.2 P/G
By splitting the data, it appears that Bellinger appeared in 200 games this season. I know that I can go look at the FanGraphs splits, but this would be nice for making quick lineup decisions.
