I think it's preferable for a young hitter to err on the side of patience (ala Bryant) rather than overaggressiveness. Viewed in that way, it isn't too surprising that they were often in difficult 2-strike counts. As they gain experience, they will learn to take fewer meatballs early in the count without becoming overaggressive. That will translate into better postseason success.
Good hitters learn to guess. Guessing pitch type and location and what pitcher is trying to do. Harder to guess when lack big league experience. Hitters HAVE to guess. Pitchers are just too good to just react without a plan of attack for the hitter. So, patience vs. overaggressiveness, sure, but a lot going on out there.
Greatest hitter of last 75 years was Ted Williams and everybody should listen to Ted Williams when he talked about guessing. Basic point is that if you're not guessing, you are not applying your accumulated knowledge about the pitcher, the count, the overall hitting situation. You are just reacting--and that's not good enough. Williams was adamant about hitters learning to guess.
So, when looking at Cubs young hitters, I would like to think that all of them are smart enough and will work hard to become better at guessing. Bryant, in particular, I'm confident will get better. He seemed to be fooled a lot and the more he learns, the better he will become at guessing.
Guessing is just another form of learning to adjust at the big league level. On the pitcher side of things, Maddux was a master guesser, right? Had uncanny knack of out-thinking the hitter. So, Cubs young hitters have to learn to guess better.
When you see a hitter who is totally clueless, such as Baez in 2014 when he was striking out a 280 K pace, the hitter isn't even in a position to guess. He is so clueless with his approach, that just
reacting virtually 100% of time. Dead meat.
Of course, good guessing is helped by getting into good hitters counts. Tough to guess with two strikes. But, we all have seen what Rizzo does lately there and it's a form of guessing too--the adjustments that he makes.
Sometimes we see a hitter take a good pitch to hit and wonder why. Often, the hitter just guessed wrong and not ready to take a good swing. It happens--even to Ted Williams. Lost that one.
Better guessing for Cubs young hitters--with experience and better hitting acumen--maybe those pitches will be hit hard. Somewhat fewer Ks too by putting ball in play before reaching two-strike counts.
