撷取文章一些重点
The most notable is the introduction of the check-swing challenge system in th
e Triple-A Pacific Coast League, beginning in early May. That allows a batter,
pitcher, or catcher to challenge an umpire’s check-swing decision against ba
t-tracking technology. MLB had tested this rule in the Low-A Florida State Lea
gue and the Arizona Fall League last year
MLB To Test Check-Swing Rule In Triple-A
March 16th, 2026 at 11:02pm CST ‧ By Anthony Franco
Major League Baseball will implement a handful of rule changes at various leve
ls of the minor leagues during the 2026 season. Eric Longenhagen of FanGraphs
first reported the slate and those interested in the topic are encouraged to r
ead that post in full.

A check-swing challenge system requires an objective cutoff point. The thresho
ld is whether the bat head breaks a 45? angle relative to the handle (essentia
lly aligning with the opposite base line). Major League Baseball’s rulebook d
oesn’t have an official check-swing cutoff, instead leaving it at the umpire
’s discretion as to whether the hitter offered.
As Longenhagen demonstrates with video, the 45? threshold is further along tha
n what umpires have generally treated as the cutoff. That led hitters to succe
ssfully challenge a lot of calls last year. It appears that’s a deliberate co
nsideration by the league. MLB’s memo notes a slight drop in the Florida Stat
e League strikeout rate after the check-swing challenge was implemented, “hav
ing a positive impact on balls in play and encouraging more extensive testing
at higher levels.” It’s not a huge effect but one that would turn more swing
ing strikes into balls than vice versa.
今年5月开始会在3A太平洋联盟PCL测试挥
棒过半挑战系统,判断标准是是球棒头部相
对於握把的角度是否超过45度,会允许打者
投手 捕手挑战,而国际联盟IL则是仅提供裁
判判决标准,不提供球队挑战。
根据去年在1A测试的结果,45度通常比裁判
判决出棒过半的临界点靠前,如影片所示,
在引入挑战系统後1A的联盟整体三振率有显
着下滑。
看似过半但实际上不到45度

1F:推 jerryklu: 一直在想45度到底从哪开始算 原来是用三垒线看 虽然有 03/17 15:35
2F:→ jerryklu: 明确规则是好事 但这跟过往惯例好像差的有点多 03/17 15:35
3F:推 carlchang092: 用平行垒线当判定标准其实也有部分裁判这样判 03/17 15:40
4F:→ carlchang092: 原因也很简单因为一般认知平行本垒板前缘 03/17 15:40
5F:→ carlchang092: 从裁判角度是斜的根本没办法有明确参考 03/17 15:40
6F:→ carlchang092: 改成45度可以让裁判也有统一判决的可能 03/17 15:40
7F:推 lowl99: Acuna表示 03/17 15:54
8F:推 Johseagull: 酷 有统一都好 03/17 16:13
9F:→ uranusjr: 改 45% 有显着下滑很合理, 和现行标准比宽松很多 03/17 16:29
10F:推 kenkuo1688: 原来是45度 我以为过本垒版就是了 03/17 18:24

12F:推 carlchang092: 原本是没有明确标准裁判自由心证 03/17 19:17

14F:→ carlchang092: 看手腕甚至身体重心什麽的都有听说被当标准 03/17 19:18
15F:→ carlchang092: 现在统一成裁判比较能一致的标准也好 03/17 19:18
16F:推 y800122155: 本垒板算90度,新规则应该是135度才对,可以再多挥45 03/17 19:38
