Baseball pitchers with insane shoulder flexibility (ESR)

Is it me or pro baseball pitchers have better ESR than pro tennis players when it comes to pitching/serving?

Pause at 0:03, his arm is literally perpendicular to his upper body.

Baseball pitchers use the uncoiling of their upper torso and that very long stride forward (opposite leg) to achieve a remarkable ESR. Tennis servers employ an upper torso uncoil and a leg drive upward to achieve a robust ESR.

I was a pitcher in college along w tennis. Here is a pic of mine.

Interesting. Have never pitched. I know that on the serve one flexes the knees at trophy position and then extends the knees to facilitate a greater racquet drop (ESR).
It looks like the pitchers still have their knees bent at the point of maximal ESR. As you mentioned, the pitchers take a stride forward. But still not clear how the pitchers achieve the severe External Shoulder Rotation without the knee flexion/extension.

When baseball pitchers take that long stride forward, they effectively leave the hand/ball behind their body. That, along with the uncoiling of the upper body, produces a very substantial ESR (backward).

Pitchers move in a horizontal direction, with their chest facing the batter, to facilitate the ESR. This makes sense since they are launching the ball in horizontal direction, more or less. Pitcher's mound is somewhat higher than home plate so the ball is actually traveling at a slight downward direction.

Tennis servers, OTOH, are launching the racquet in an upward direction (closer to vertical than horizontal). As the upper torso uncoils, the chest and the racquet shoulder are driven upward. The ESR for this will be in a downward direction (rather than a backward direction). This is why tennis servers employ more knee bend and the legs drive primarily upward rather than forward. (There is actually a moderate forward component to the leg drive for the tennis serve compared to its upward component).

I’d say, during that long stride they create linear momentum of body which then converts into rapid torso rotation as they plant the front foot, so the back shoulder accelerates creating stretch against the “left behind” arm holding the ball. One cannot plant against air, so with upward swing we use our tools in a different way collecting most power from more concentrated upward drive.
