Solo che dai, ogni tanto ci vuole uno che risalti anche (quel poco di buono che c'è) l'old school...

Tu sei l'unico che legge il topic dei Dodgers quindi sai quanto faccia caso al comando di Kershaw dopo ogni sua partenza, visto che la paura di perderlo è sempre dietro l'angolo. Questi sono aspetti che si possono notare solo guardando la partita

Hobbit83 ha scritto:L'altro giorno mostravano uno "statcast" di keuchel e veniva indicata la velocità di uscita del lancio e la "velocità percepita". Cosa sarebbe quest'ultima?
Negli esempi che mostravano, era sempre leggermente inferiore alla prima (roba di meno di un mph).

Renè, mi sviluppi questo concetto di overstride per favore?
Precisamente, sul lancio tecnicamente, di che si tratta?

Apertura del compasso molto esasperata verso casa base.

Last year Trackman installed its ball flight measuring systems in a handful of major league and minor league parks. The data provided a trove of information that makes the radar gun, a staple of baseball since the early 1970s, seem as obsolete as the typewriter.

Why is Robertson so difficult to hit? According to Trackman's measurements taken in one American League park last season, Robertson, with his exceptionally long stride and reach, released his fastball seven feet from in front of the pitching rubber -- the largest average extension Trackman measured in that park. The average MLB fastball extension was five feet, 10 inches.

Imagine if Robertson moves the pitching rubber 14 inches closer to home plate every time he pitches. That's the kind of advantage he gains over the average pitcher by releasing his fastball with so much extension. The radar gun (and Trackman) clocks Robertson's fastball at an average of 93 mph. But because Robertson shortens the distance between his release point and home plate, his "effective velocity" is 95 mph. It looks like 93 but gets on a hitter like 95 -- thus the illusion of "hop."

Robertson, che fra l'altro è 5'11 da altezza elencata, mentre Kershaw e Harvey sono 6'4, gambe decisamente diversamente lunghe. Robertson ha gambe più corte, ma ha lo stride più lungo in Major League (35 cm sopra media) nonostante ciò... e capisci QUANTO vada in overstride, per farlo.
