I've been intrigued by the Korean/Japanese hitters lately, Son and Kim included.
I believe that I commented on their "pause/pose" at the top of their swing. They wait......which makes all the difference on their weight.
As I've thought about it (and I have), I've begun to think that the difference is really that of lateral vs. rotational movement.
The "modern" swing is the one we've seen in the Tom Emanski videos (which drive me batty). This is a rotational move, with bat speed generated by the hips exploding open. Lookie here, at our own Boomstick Baby:

That move is rotational. There is little slide forward, almost none. The hips explode open and the bat follows. It is an around and up move. You'll see something like that in the modern power golf swing. McIlroy and Johnson demonstrate here: https://www.youtube.com/watch?v=YuEATi-0HMM
This is a move that generates maximum bat/club speed. It is a relatively modern (successfully, anyway) golf move: The golf ball spins/curves less today than the old ball used to. It is designed that way. The rotational move maximizes power and sacrifices little accuracy, since the ball spins sideways less. In baseball, the rotational move maximizes swing speed.
In either sport the player gets to the front leg more quickly. That leg gets straighter earlier.
The "old move" is lateral. There is a clear slide. There is a "flex" that keeps the batter low. The back leg is much more bent as the batter gets on top of the front leg. This is a move "into" the ball. The bat releases later and I think (in baseball) the batter gets a better view of the ball for a longer period of time.
I've been looking at video a bit and I found this: Ted Williams: I can't think of any thing I've seen that better describes what I'm speaking about: https://www.youtube.com/watch?v=EpMlVptg2Ls
Aaron is lateral ("Gaining ground," as the guy says): https://www.youtube.com/watch?v=sfJFhxWwiu4 Mays, too: https://www.youtube.com/watch?v=302SYEjg1Ac
Here's a quick view os Sadaharo Oh's move: https://www.youtube.com/watch?v=wj8SNYxzRCk And Ah-seop Son move "into" the ball, not around his center: https://www.youtube.com/watch?v=wj8SNYxzRCk
In golf, the best ball strikers in history may be Lee Trevino, Moe Norman and Ben Hogan: Witness:
Hogan was pretty rotational for his day, but "chases" the ball, "down the line" much more than Johnson or McIlroy do today. https://www.youtube.com/watch?v=nWLLPKiSMRk
Trevino: Nobody chased it better than him:

Moe Norman: He is likely the best ball striker in the history of golf. His move is down the line and his finish is incredibly reminiscent of the great Asian hitters in baseball: https://www.youtube.com/watch?v=9vdS4ifJ4IA
Ball strikers, as opposed to power hitters, hit the ball squarely and hard, nearly all the time. I commented on the Sons and Kims, who seem to hit opposite field HR's, often right down the line, yet don't seem to be "going the other way."
They go down the line, in an old time move, delaying the release, yet hitting the ball squarely. Is it better than the "modern" (see Cruz) swing? I don't know...but it fits my eye much more wonderfully. There is a smoothness, a go slow to go fast, that seems just right.
Go to 1:26 in this video to see the "OriginaL' Boog Powell, a big guy, "slide" into the ball. https://www.youtube.com/watch?v=L1E5Ltv58sU
I love it.
There is a posed and paused element to the old time swing. The move into the ball is lateral and controlled. The batter (or golfer) "meets" the ball much more than he attacks it. We've lost this swing. I want to find it again.
