I mostly agree with the direction you’re going, but I think the real inflection point here is usage context, not just pitch diversity. The Cubs’ recent acquisitions suggest they’re prioritizing shape separation and tunneling efficiency more than raw unpredictability for its own sake. A high-velo 4-seam paired with a true splitter does create vertical separation, but only if the release consistency holds up under leverage.
The question for me is whether his splitter actually plays as a bat-misser at the MLB level or if it’s more contact-management driven. If it’s the latter, I’m not sure it meaningfully moves the needle compared to what they already have. That said, the WHIP profile is hard to ignore, especially if it’s supported by weak-contact metrics rather than BABIP luck.
I also wouldn’t underestimate age curve here. If the Cubs see him as a short-term volatility stabilizer rather than a long-term bullpen anchor, the fit makes more sense. Giants feel like the obvious fallback, but Chicago has been quietly willing to bet on pitch-mix upside lately, even if the surface numbers don’t jump off the page.
So yeah — not a lock, but if they’re optimizing for diversity + cost efficiency, I can see the logic.
