你只看他的上半身其實沒啥用 投球機制就是timing
身體哪一個部位 哪一個時間 該出現在哪一個地方
不過能站在職業投手丘上的 看arm clocking基本上都能猜到他下半身的相對位置
說inverted W 我們就來看一個大聯盟投手牛棚的影片
sonny gray
比起6"4的100mph火球男
5"10的sonny gray跟5"8的marcus stroman都是投球機制比那些火球男更優異
才能投到97 98
一般來說一個很好的check point就是前腳落地的瞬間 arm clocking的位置
如果地面垂直是90度 水平是0度 那大概會在45度左右
90度被稱為early clocking 除了bartolo colon以外
很少有大聯盟投手會出現early clocking還能丟出95+
0度是late clocking
回到sonny gray的牛棚 你看他落地的前一刻手還在這邊

對比黃恩賜大概是這個位置

他前腳落地那一瞬間 arm clocking就到相當理想的角度
大概45~60度之間 當然有可能是因為是牛棚沒有全力丟 或者影片取樣率問題
這看起來比較像是60度

hip rotation結束後 arm clocking達到90度
也就是所謂的hip shoulder seperation

對手肘壓力大的瞬間只有external rotaion 到 internal rotation & ball release
這一點無解 球速越快 手肘的壓力就越大
除非像是Aaron Sanchez這種只靠上半身丟到97
那可能選手壽命會短一點
良好的投球機制
利用投手丘與重力 + 穩定的lead leg block把linear power轉換成rotation power
優異的下盤+髖關節爆發力創造出來的hip shoulder seperation
一樣的球速 自然更能能分擔肩膀跟手肘的壓力
※ 引述《s9209122222 (海海海)》之銘言:
: 從他的慢動作來看,他貌似有很嚴重的 inverted L,
: 前臂也是肩膀開始轉動才舉起來,他的球速又比大部份中職選手快,
: 這對手肘壓力非常大吧?
: 這不是 flat arm syndrome 嗎?
