A favorite question of the baseball audience is, when does a small sample start to have meaning? There are a few general rules of thumb, but in large part it’s still a question, I think, because there is no perfect answer. It can be a gut thing, or it can be a matter of magnitude. I don’t care if a batter starts out 6-for-10 with three home runs. I’d care a lot more if a batter were to start out 8-for-10 with six home runs. Some performances over small samples are so very good — or so very bad — that there almost has to be signal. Even over a short amount of time, it’s hard for a player to fluke his way into the extremes.
Over the winter, the Rockies invested heavily in their bullpen. You could argue they invested *too* heavily, but, well, this is the bullpen era, and you’d figure the Rockies, of all teams, might need to keep theirs both deep and refreshed. It’s a bullpen with plenty of interesting arms, but the most important reliever might be Adam Ottavino. In the past, Ottavino has been genuinely dominant. Last season, he came off the rails, with a walk rate of 16%. With a bad Ottavino, the Colorado bullpen might not be a strength. With a good Ottavino, it would go four or five deep.
It’s early. But, as early as it is, Ottavino has faced 34 batters, and he’s struck out 22 of them. He’s walked one guy, he’s allowed one run, and he’s given up two hits. Nearly half of all swing attempts against Ottavino have missed. Nearly half of all swing attempts against Ottavino pitches in the strike zone have missed. Only Josh Hader might rival what Ottavino has done. This is a small sample that’s so good, it’s crying out to be investigated.
The results are almost unbelievable. It turns out Ottavino also has an exceptional process.
