I should have put this disclaimer gif on my first post, lol.
I'm well aware of the dynamic you've described. In fact, had Royce ate his cheerios this morning and hit that 3-run home run, Pablo's contributions would be all for naught. WPA speaking, of course.
I've read the articles, I know how it works. There is a fantastic bit of statistical gymnastics involved in telling the "story of the game" without defense or any meaningful measurement of the starting pitcher (unless he really sucks, like Sears). These last two games are outliers in modern baseball so the modern analytical model struggles with them, one on the bottom side with Ober and one over the top with Pablo.
Any statistical measurement attempting to tell us who was responsible for the winning of any specific game that gives a pitcher that throws a complete game allowing 4 (four!) baserunners a negative value is broken. Period. Back to the drawing board. The hypothesis is defeated.
If I'm being honest, just don't rate pitching with WPA. It overvalues relievers, undervalues starters and doesn't attempt to factor defense. Just use it for offense and it won't be offensive.
Also, really good clean game. I wish Buxton would hit that pitch on the outside edge to center or right center but I'll take left center when it works.
