Back in July of 2013, I put together a little bit of research to put Michael Cuddyer’s 27-game hitting streak into perspective. I had been quite critical of Mr. Cuddyer at that time, and it only seemed fair to show him a little love. At the time, I mentioned that I might look into some more hitting streak data in the near future. Turns out the “near future” was three years later. Spurred on by the recent hitting streaks from the killer B’s on a swarm — Jackie Bradley Jr. and Xander Bogaerts — I thought I’d wade back in.
First, as I mentioned last time, a couple of ground rules. I don’t count streaks that span two seasons. I don’t like doing it, and you can’t make me. Second, there are some streaks that took place from the time before we have game logs. When I first conducted this research, the earliest season for which we had game logs was 1916; now it’s 1913. Fortunately, for the sake of convenience, no relevant hitting streaks occurred during 1913-1915, so we’re not getting any new information in that respect.
We are getting some other new information, though. For instance, Baseball-Reference has WPA calculated further back than they did before, so where before we didn’t know the WPA of Joe DiMaggio’s 56-game hit streak, now we do have that figure. We also have a few more years of streaks in the mix. The cut-off for WPA data now seems to be 1930, though there was one streak from 1943 for which WPA information appears unavailable.
