年初寫了一篇文章討論彈力球議題,你可以不用點但還是附上連結:
https://reurl.cc/62G9mr
主要觀察到的結論是:
1. 過去幾年的Exit Velocity並沒有明顯的增長,至少可以確定即使彈力球存在,其效果
也不是增加EV
2. 過去幾年的聯盟Launch Angle一路發
3. 在創造更好的Launch Angle x Exit Velocity組合上,打者是顯著進步的。比起飛球
革命,更重要的進步是打者更知道怎樣的EV/LA是最應該被創造的
4. 如果彈力球存在,其效果應該是「兩個同EV同LA的batted ball,彈力球會飛得更遠」
5. 對於4所提到的情境下去用模型模擬,EV/LA = 100/25時,2019年的球平均比2018多飛
了5ft
6. 彈力球的bonus會隨著EV變高而提升
7. 從19年季後賽的有限樣本中,頗懷疑季後賽跟季賽用球不同
