Baseball's Surprising Stats: When Projections Deceive
The baseball season is off to a thrilling start, and as the excitement builds, we're diving into some intriguing observations that might just ruffle some feathers. But first, a disclaimer: this article isn't your typical projection piece.
The Power of Gut Instinct vs. Data
I've noticed a fascinating trend this spring: my gut feelings about certain pitchers are often at odds with the data. Take Bubba Chandler and Mitch Keller, for example. Their four-seam pitches looked dreadful in their initial starts, only to appear perfectly fine in their subsequent outings. And it's not just them; Richard Fitts' four-seamer and sweeper exhibited significantly more movement on a particular day, and Rays prospect Ty Johnson's four-seamer had an additional 3 inches of vertical break compared to last year, all without any apparent changes in technique.
Now, I'm no expert in stuff models or environmental adjustments, but I suspect wind might be a significant player in these anomalies. Baseball analyst Vivienne Pelletier has pointed out that crosswinds can alter a pitch's trajectory by up to 4 inches. Moreover, Robert Stock, a renowned baseball thrower, has noted that air density can also impact pitch movement.
So, here's my take: when I observe a substantial increase in movement without any corresponding changes in pitching mechanics, I'm inclined to trust my instincts. I'll assume the pitcher hasn't made any adjustments until 2026 MLB park data proves otherwise.
The Nationals' Pitching Puzzle
Now, let's focus on a team that struggled with pitching last season: the Nationals. Their projections for 2026 are not looking promising, with one pitcher, Irvin, expected to have a ~5.00 ERA in ~20 starts. But here's where it gets controversial: the Nationals seem to be reducing their four-seam and sinker usage, which is intriguing because they led the MLB in fastball throwing last season at 55%.
In spring training, the Nationals have thrown fastballs just 41.7% of the time, the second-lowest in the league. Irvin, in particular, has reduced his four-seam and sinker usage to 40% this spring, a significant drop from last season's 54%. He's also adjusted his approach against lefties and righties, favoring the curveball (30%) and cutter (25%) against the former, and increasing short slider usage to 23% against the latter. This strategy aims to reduce the reliance on the four-seam pitch, which was hit hard by both lefties and righties last season.
And this is the part most people miss: while the Nationals' strategy might seem counterintuitive, it could be a clever way to improve their pitching performance. Sometimes, the key to success is not just about adding new elements but also about subtracting the ones that aren't working.
As we eagerly await the regular season, remember that projections are just that—projections. They provide a glimpse into the future, but they're not set in stone. So, what do you think? Are the Nationals onto something with their pitching strategy, or is this a recipe for disaster? Share your thoughts in the comments below!
