Major League Baseball just confirmed a pretty big rule change for 2026: the ABS (Automatic Balls and Strikes) challenge system is coming. This tech upgrade will shake up how the strike zone gets called, and it’s already sparking plenty of debate among players, coaches, and fans.
For elite defensive catchers like Patrick Bailey of the San Francisco Giants—who’s widely seen as the best pitch framer in the league—the impact could be huge. Bailey built his name on turning borderline pitches into strikes, but with ABS, technology and real-time challenges will take over more of those calls.
The ABS Challenge System: How It Works
They’ve tested the ABS system in Triple-A and during spring training, and it’s looked pretty accurate and quick so far. Under the new rules, pitchers, catchers, or batters can challenge up to two calls per game.
If a challenge is correct, the team keeps it. In extra innings, each side gets one more challenge.
This could totally change the dynamic of calling a game. There’ll be less focus on human judgment and more on what the computers say.
Technology Behind the Change
Every stadium gets 12 Hawk-Eye cameras tracking pitches with serious precision. Once someone challenges a call, the system spits out a result in about 15 seconds.
Fans will see a visual of the pitch and the strike zone, kind of like tennis replays. It keeps the game moving but adds a fresh bit of suspense for everyone watching.
The Impact on Patrick Bailey
Bailey’s got a rare skillset. He can turn borderline pitches into strikeouts—he just did it in a recent Giants game—and he’s at the top of the league in Catcher Framing Runs.
That elite framing is a huge part of his defensive value and a big reason he’s put up a solid 3.2 fWAR this year, even though he’s only hitting .224 with six homers.
Framing Under ABS Rules
Giants manager Bob Melvin thinks Bailey’s framing will still matter. Since teams only get a couple of challenges, they’ll probably save them for big moments instead of every close call.
Bailey’s sharp strike-zone feel could still sway umpires on unchallenged pitches. So, defensive catchers might stay pretty important, even with all this tech in the mix.
What the Numbers Say
Minor league data from ABS experiments shows an interesting split:
- Pitchers challenge calls correctly just 41% of the time.
- Catchers like Bailey succeed 56% of the time.
This edge shows that, even with ABS changing things, skilled catchers should keep a leg up when it comes to knowing when to risk a challenge.
Concerns and Opposition
Some players and teams have their doubts about the new system. They worry about too many challenges, messing with the game’s flow, and maybe even embarrassing players who guess wrong on pitch locations.
It’s another round in the ongoing tug-of-war between old-school baseball instincts and the analytics crowd.
Fan Experience and Added Drama
On the flip side, supporters say ABS will give fans something new to cheer for. Seeing the real spot of a pitch on the big screen in real time could fire up the crowd, kind of like replay moments in other sports.
The extra transparency might cut down on those frustrating, head-scratching calls too. That could make the game feel a bit fairer—or at least more honest.
Bailey’s Own Take
Bailey’s been pretty cautious about ABS. He knows it could take away some of the value from framing pitches, which might push him to hit more to keep his spot.
Still, with his instincts and defensive chops, he should stay one of the Giants’ top assets. I’d be surprised if he didn’t find a way to keep making a difference.
The Future of the Catcher Position
The implementation of ABS in 2026 isn’t just a technological shift. It’s forcing everyone to rethink what makes a catcher truly valuable.
Offensive stats might matter more than before. Still, defensive skills—especially when it comes to winning challenges—aren’t going anywhere.
Bailey’s got a shot to turn what looks like a hurdle into a chance to stand out for the Giants. If he adapts fast, he could prove he’s more than just a good glove.
MLB’s move toward the ABS challenge system is going to change the whole dynamic between pitchers, hitters, and catchers. I can’t help but wonder how defenders like Patrick Bailey, who really know the strike zone, will adjust.
Some catchers will fade, but the ones with sharp instincts and a feel for the game should hang on—even as baseball keeps mixing old-school grit with new tech.
