There’s no hiding from it — baseballs in the major leagues are being pitched faster than ever before, on average. I mean, we don’t have all that much of a record, but the trend is blatantly obvious over the past 10 or 15 years, and it stands to reason it extends ever back. A few years ago, this was a really interesting observation. Now, it’s something everyone already knows. Pitchers throw harder than they used to. That’s a given. Seemingly every bullpen now has an arm or three who would’ve been a certified flamethrower a decade ago.
Why is this happening? It’s important to try to understand the reasons. There are a lot of ideas out there, many of them valid. There’s a belief that, in general, teams are increasingly obsessed with velocity. And bullpens are being used more aggressively, with relievers throwing harder than starters. Newer training techniques are getting more out of young pitchers, so pitchers also just arrive throwing harder. You’ve got teenagers throwing harder, and teams looking for powerful arms and promising bodies — as a consequence, between 2002 – 2004, rookie starters threw their fastballs a hair under 90. The last three years, that average has gone up to 92. Why the increased velocity? “Youth” is a common response.
It’s definitely a big part of the answer. It’s not all of it. I think there’s something else happening, and it can allow us to link a number of this offseason’s free agents.
