球速和月份的关系:
Month Speed correction value Avg. temperature
April -0.28 68°
May -0.10 72°
June +0.07 81°
July +0.13 84°
August +0.14 82°
September +0.07 75°
四月天气冷 投手果然球速比较慢 要到八九月天气热时球速才变比较快
早午晚场比赛:
Time of day Pitch speed (relative to evening)
Mid-day -0.12
Afternoon -0.03
Night +0.07
Wee hours +0.05
看来投手不喜欢在阳光下投球
用球数:
Pit Speed (relative to first 20 pitches thrown)
21-40 -0.13
41-60 -0.19
61-80 -0.38
81-100 -0.46
101 + -0.32
除非是V壮这样配速投球 不然大家都是愈投愈累然后球速下滑
快乐枪:
Ballpark Speed difference (relative to neutral park)
Kaufmann Stadium (KC) +0.83
U.S. Cellular Field (CWS) +0.55
Fenway Park (BOS) +0.48
Nationals Park (WAS) +0.42
Progressive Field (CLE) +0.31
Wrigley Field (CHC) -0.30
Yankee Stadium (NYY) -0.33

wee hours 是不是上场的大多是后援投手的缘故?

2012-05-13 15:39:00#1DkhggbO (MLB) 就客队投球时调低
感谢WLR大！是说我有点不懂为什么要那样，就算数据上
看起来比较慢，但对打者而言速度不会变慢呀Orz好像没什么实益...(小声)

搞不好真的是球场跟气候造成投手球速增减压@@?
作者: hikaruton (Tonia~黄色希卡鲁) 2012-05-13 23:07:00
所以对打者而言 实际上还是快了点或慢了点
