Welcome to baseball in 2026, where technology is changing the game in ways nobody anticipated.

The new Automated Ball-Strike Challenge System — baseball's answer to replay review for balls and strikes — has an interesting wrinkle that's causing confusion. Players must challenge immediately, before making any other movements. And by immediately, MLB means immediately.

Cavan Biggio learned this the hard way in a spring training game. According to Jomboy, Biggio took what should have been ball four. But he flipped his bat in celebration before tapping his head to signal a challenge. By the time he signaled, it was too late. The challenge was denied because he'd already made another movement.

So instead of taking his base, Biggio had to stay in the box. That's... something.

Look, I'm not anti-technology. Replay review has been good for baseball. Getting calls right matters. But this? This creates situations where a player's natural celebration instinct can cost them a walk. That's absurd.

Imagine you're a hitter. You just took a pitch you think is ball four. Your brain processes: "That's a ball. I'm going to first base." You flip your bat. Oops. You just lost your right to challenge. Hope you were right about that pitch.

The system is supposed to give players agency — the ability to challenge calls they think are wrong. But if the window to challenge is so narrow that a bat flip disqualifies you, what's the point?

Baseball is a game of instincts and reactions. Players have been flipping bats and dropping bats and tossing bats for over a century. Now we're asking them to override that instinct, assess whether they want to challenge, and signal the challenge — all in the split second after a pitch.

This is going to create so many weird moments this season. A player celebrates a big hit, realizes it was called a strike, too late to challenge. A batter starts to walk, remembers the rule, frantically waves for a challenge before his foot moves. It's going to be chaos.

Maybe MLB will adjust the rule as the season goes on. Maybe players will adapt and learn to challenge first, celebrate second. But right now, we're in a weird transition period where baseball's most fundamental moments are governed by rules even the players don't fully understand yet.

This is what happens when you layer new technology onto an old game. Sometimes it works seamlessly. Sometimes you get a guy losing ball four because he flipped his bat a half-second too early.

Welcome to the future, folks. It's complicated.
