As a pitcher’s parent after watching someone get a free pass or a hit after what seemed like a third strike to me via my perfect viewing angle in the stands or on TV (lol) I’ll say something like “Seems like you were squeezed a bit today”. There’s only been a couple times in college or lower-level pro ball where the response will be something like “Yeah, that blue was trash today”, mostly it’s “The blue was ok and pretty consistent” In the MLB, he’s talked about how amazingly consistent the blues are, and takes the anomalies as part of the game. Parentally, I handle the anomalies with profanity under my breath in public, and not so much at home…
I will say at the MLB level a great catcher that understands the pitch movement of his staff does steal a few strikes. It’s a game within a game I’d not paid attention to until last year, and I think I’ll miss it if it goes away.
