My streaming box buffers about 1 minute behind, so I was waiting with bated breath as to what Mike was talking about here.... Bryce (Took me many months to realize my box buffers, which was made obvious during New Years countdown, as we heard loud sounds in our neighborhood, while counter was 58)

What a FANTASTIC clip to make this point: This is ... (almost definitely) ONE constant swing plane ... (very probably) SIX different attack angles ONLY way for any pair of those balls to have same attack angle is if each ball "passes through" (exactly) the next ball.Which is practically impossible

The extra inning runner is the ONLY rule with opposition. That's true of every overtime rule that is used in regular season and not playoffs in any sport Otherwise, all the new rules were overwhelmingly positively received by the fans

Old ballplayers lament new rules? If there's anyone that does NOT have the pulse of the baseball nation it's old ballplayers C'mon, if you want me to run a poll over on Twitter, we'll get at least 80% if not 90%+ in favour of no-pitchers-batting

Height v Stance is an ENORMOUS change Given that there is no definition of a swing to begin with, there's no "change"!

Tangotiger @tangotiger.com · 22/09/2026
That's not actually unwritten either. The gray area is between front-of-plate (10% swing rate) and foul line (90% swing rate) At about 20 degrees is the 50/50 swing rate call Folks are just making up the defacto / unwritten rule based on whatever the TV producer is showing

On full counts, batters have 40 pitches outside strikezone and 42 inside Since a walk has wOBA value of 0.7 and strikeout is 0.0, then taking all 82 pitches would result in wOBA of 40*.7 / (40 + 42) = .341 League-wide wOBA on full counts is .376 Getting Miz at .341 is success

Solution to issue of teams using #EBUP (emergency backup pitchers): Every fan in attendance gets 20$ voucher, or 25% of face value ticket price, whichever is higher, paid by the Pitcher In NHL, #EBUG use requires fans in attendance to PAY extra 1$ each: it goes to the goalie

In terms of standings, the games that are most important are those that involve your direct competitor in the standings, since a W for you is an L for them Otherwise, it's just bullsh!t fans say, on top of all the other bullsh!t fans say. We don't need to respond to all the bullsh!t

I should add my entire career would not have developed as it did Consider that MLBAM had its initial scoring system modelled on the Retro/DiamondWare scoring system. Without that, it delays MLBAM event files by a few years, as well as my book and WAR by a decade. Thousands of my peers are affected

Ironically, JJ Wetherholt & Sal Stewart have exactly the same wOBA with runners on, .348. JJ better OBP, Sal better SLG. Stewart has 74 more PA with runners on. But he drives in a runner once every 3 PA w/ runners on, and for JJ it's once every 5. It's both things.

I think the intent of the rule is that we dont care about the intent of the batter Its simply an objective definition that the batter is aware of, so he knows how aggressive he can be and when he can stop his swing in time

Yes, obviously you IBB the best batter on the opposing team when that run is irrelevant to the game

You need to specify if it was bottom/top. I presume it's bottom, since I saw a tweet with a fight in the stands with Cubs jerseys And then I need the score. Was it tied, and so the IBB makes that run irrelevant?
