To Walk or Not to Walk
In my head, the playoffs have always had a unique relationship with analysis. Things are happening, always new and exciting things, and I feel a strong desire to know what’s skill and what’s luck, to sort out whether Adam Wainwright found the secret formula to pitching or whether he just had a good breakfast Sunday, while the Braves stubbed their collective toes on the hotel bed frame.
But for the most part, there’s not much to say conclusively about one pitching outing, or even a few pitching outings. The samples are vanishingly small in the postseason, and so I watch for the narratives and the drama, rather than trying to find an interesting line to analyze. Sure, I have opinions about the players in the playoffs, formed from a year of crunching numbers on their performances. But for the most part, I don’t use October to tell me new things about them.
If Patrick Corbin comes in and gives up six runs in relief, is he bad? Is he unsuited to relieving? Did he just not have it that day? I don’t know, and short of some velocity or spin rate smoking gun, I’ll probably never know.
Having said all that, there’s one thing I feel very comfortable analyzing. Managers still walk people intentionally in the playoffs, and maybe they shouldn’t. Dave Martinez and Mike Shildt succumbed to the temptation of making a difference over the weekend, and while neither decision ended up impacting the final accounting of the game, I was curious to see what those walks did to the teams’ chances of winning.
Let’s talk about Martinez’s decision first, because it’s much stranger. We’ll set the stage with all the essentials: in Game 2 of their series against the Dodgers, the Nationals took a 4-2 lead into the ninth inning, with Daniel Hudson taking the mound following a dominant inning by Max Scherzer. Justin Turner doubled to start the inning, but Hudson rebounded, striking out A.J. Pollock and getting Cody Bellinger to pop out to third. Read the rest of this entry »
