Get ready for a thrilling baseball season! As we embrace the arrival of spring, it's time to dive into some exciting insights about the game. Today, we're uncovering a hidden gem that could challenge conventional wisdom.
I'm thrilled to share my upcoming 1-30 system pitching development ranks, based on insights from over 50 MLB coaches and executives. It's an exclusive glimpse into the world of baseball analytics, and I can't wait to reveal it next week!
But here's where it gets controversial... I've noticed some intriguing data this spring that doesn't quite align with my instincts. Take the four-seam shapes of Bubba Chandler and Mitch Keller, for instance. Their initial starts were underwhelming, but they bounced back in their second outings. Richard Fitts' four-seamer and sweeper showed significantly more movement on February 25th. And Rays prospect Ty Johnson? He's throwing a four-seamer with a remarkable 3-inch increase in vertical break, without any changes in release or spin.
Now, I'm not an expert in stuff models or environmental adjustments, but I suspect wind is a major factor in these games. Baseball analyst Vivienne Pelletier highlights how crosswinds can impact a pitch by up to 4 inches. When you consider the unique wind fingerprints of spring training parks, which lack the second and third decks of MLB stadiums, it's clear that these environments are vastly different. Robert Stock, a noted baseball thrower, also emphasizes the role of air density in affecting Stuff+.
In summary, if I see a significant increase in movement without changes in slot, release, or spin, I assume the pitcher hasn't changed. We should stick with their 2025 regular-season shapes until 2026 MLB data proves otherwise.
Let's take a closer look at Irvin, one of the worst pitchers in baseball last season. I predict the Nationals will significantly reduce their four-seam and sinker usage. As a team, they relied heavily on fastballs last season, throwing a league-leading 55% combined four-seam and sinker. This spring, they've dialed it back to just 41.7%, the second-lowest in the league behind the Marlins.
Irvin, in particular, has reduced his four-seam and sinker usage to 40% this spring, down from 54% last season. Against left-handed batters, his curveball has become his primary pitch, with a 30% usage rate, while his cutter follows at 25%. Against righties, he's tripled his short slider usage to 23%, a strategic move to reduce four-seam usage, which allowed a high barrel rate to both righties and lefties last season.
Irvin's projections for the upcoming season are not looking great, with an estimated ERA of around 5.00 in approximately 20 starts. However, his efforts to diversify his pitch selection and reduce reliance on the four-seam could pay off.
So, will Irvin's adjustments make him a success story, or will he continue to struggle? What do you think? Share your thoughts in the comments and let's discuss!
