Doesn't need to be like that. Bases empty and/or not a close score, it makes no difference what resources the opposing manager has. But if the other team has a lefty or two they can bring in each time the game hangs in the balance with one of our corner guys due up, it's a disadvantage.
The solution of course is for the new batting coach to figure out what the previous one(s) apparently could not, namely how to bring these lefty hitters to the level of accomplishment they need to be once they reach the majors. I don't think Keirsey, Wallner, or Larnach showed the extreme L/R splits in the minors like we've seen in the majors (Keirsey being the smallest of major league SSS of course, but he still managed to fit the unfortunate pattern). It's uncanny how our lefty hitters, possessing normal/small L/R splits in the minors, seemingly all get spooked by LHP when they come up, deer-in-headlights style.
Referring to handedness is of course shorthand. There's the old cliche that "I don't care which hand he throws with, I want a pitcher who can get lefties out," and the corollary for batters is obvious. Correa hits righthanders exceedingly well (even if he succeeds even more against lefties). Lewis is a little hard to figure, given his second-half swoon, but the overall stats for his 2024 show a guy who was playable when facing a right-hander and did better than that against left-handers. L/R splits are something almost every batter has, and you can live with that, as long as he's playable either way.
The key is, when are they playable. Correa is totally playable against RHP, and Lewis shows no sign that he isn't playable against them, either. Wallner and Larnach, just going by results so far, are simply not playable against LHP, Adding Keirsey to this mix, based on empty results in a mere 4 PA in 2024, threatens to be toxic unless solutions are found pronto.
Or, maybe Buxton can hang in there for 150 starts in CF, and make my concern moot. 😀
There are various solutions to this L/L/L alignment in the outfield, a few of which I've alluded to and there are obviously others. My point is that I can't simply ignore it, when deciding whether to roster both Larnach and Waller. They aren't good enough, yet, to let me.
