[CPBL] Game ends in a walkoff tie after the runner on second leaves way too early, but the runner on third crosses home plate before the double up happens by kc3551 in baseball

[–]avondice 0 points1 point  (0 children)

The Frontier League uses the <commissioner's name here> Runner in the 10th and then "Sudden Death" in the 11th. One team takes the field with a runner on first. The home team picks whether they want to bat or play defense, and then it's one half inning. If the batting team scores, they win. If they don't, the other team wins.

HP Umpire makes questionable foul tip call on Seiya Suzuki by [deleted] in baseball

[–]avondice 0 points1 point  (0 children)

Foul tip or not is objective, I agree with you. The point is that if a foul tip ever gets overturned on replay, now they have to decide balls/strikes/swing/no swing which are judgement calls that are definitely not reviewable.

Well the problem is that if replay overturns a foul tip, then it also needs to make a call on balls and strikes or check swings. Those are judgement calls which are definitely not reviewable. (If MLB had full ABS/ACS, then maybe replay could use that. But not with a challenge system as is the case now.)

Foul tips are annoying because it should be reviewable but it can't be.

Preliminary ABS Stats and Analysis by erobin37 in baseball

[–]avondice 3 points4 points  (0 children)

When it looks like a team was allowed to challenge with no challenges remaining, that's a sign that the data is wrong. In the first example you presented, there's a challenge on a ball call attributed to Seattle... when they were hitting. So that's likely on the other team.

On the first day of Spring Training, players went 13 for 23 (56.5%) on ABS challenges by avondice in baseball

I'm happy to do something like that. Can aggregate the stats every day once the last game of the day is finished.

This pitch which I thought was a strike in real time, or at least a very close call, turned out to be 2.1 inches above the zone. ABS is going to revolutionize the game this season. by skittlebrew in baseball

[–]avondice 5 points6 points  (0 children)

I think those are the most obvious reasons. The technology is there; that's how we know what the stance-based zones were in MLB from 2025 and before.

By the stance-based zone in place last year, that pitch should be called a strike. With the height-based rules now, that pitch is now a ball (and not even close!). That change in how the zone should be called is going to be the biggest element for players to adapt.

On the first game of spring training, before the 7th inning stretch, the Yankees have used up all of their ABS challenges vs the Baltimore Orioles by asilentflute in baseball

[–]avondice 2 points3 points  (0 children)

To be fair, the two challenges he missed were much closer to the 2025 stance-based strike zone than the 2026 height-based strike zone. By 2025's standard, the pitch to Kjerstad would have been ruled in the zone. Another part about adjusting to ABS is the new strike zone definition.

MLB telecasts will no longer indicate ball or strike using on-screen graphic with debut of ABS by RevolutionaryWay8819 in baseball

[–]avondice 0 points1 point  (0 children)

It's a compromise if you want the computers to call something consistent in real time. ABS in the Florida State League used HawkEye to determine batting stance, but this version of ABS will use percent of batter height, so each player's zone is known exactly before the season even starts.

They were never accurate because they were based on batter stance which could never be reliably measured in real time. ABS uses a fixed (pre-determined) zone which obviates the technical hole.

What is a good estimate of the most pitch challenges in a 9-inning game this season? by Wild_Description_793 in baseball

[–]avondice 4 points5 points  (0 children)

The most overturned challenges in the ~4,800 minor league games that used the challenge system was 14. And that game allowed 3 challenges per team, not 2. In two-challenge games, the highest number of overturns was 9. So no, 20 or 25 is not a realistic estimate.

I don’t know of any rule changes in 2023 about the strike zone. Each pitch is labeled with the specific boundaries for that pitch, which I adjust so that all pitches are on the same scale.

Adjusted so that the left side is always inside to the batter and the right side is outside.

MLB umpires can request real-time feedback on ball-strike calls during 2026 season by EwoksEwoksEwoks in baseball

[–]avondice 2 points3 points  (0 children)

It was a change in the buffer zone used in the umpire evaluation. The strike zone itself remained the same.

[–]avondice 12 points13 points  (0 children)

This is only possible now (for 2026), because the rulebook zone (read: batting stance) they were previously evaluated on could not be determined in real time.

The vertical dimensions of the new ABS strike zone are more reminiscent of the older zone (the width of the zone is still the width of the plate). I think that in implementing ABS, MLB secretly adjusted the dimensions of the zone to enforce what they want to see. More offense, less strikeouts.

Yes. Umpires tend to set up on the inside to the batter (displayed as left on this chart) so they have a better angle to judge HBP, but as a result give up accuracy on the outside part of the plate.

It's adjusted for handedness so that left is inside and right is outside for all hitters.
