SAN DIEGO — When you follow a game on Major League Baseball’s website, it’s there. When you watch a local broadcast, there’s a good chance you’ll see it. When you see an ESPN broadcast, it’s part of the live picture.

Graphics showing the strike zone, telling viewers immediately whether a pitch is good, are standard fare now. For the most part, they show us how good umpires are at getting borderline ball-and-strike calls right. They also show us every call that is missed.

Considering that tennis already has mechanized officiating, with other sports implementing technology in their own ways, it’s fair to wonder about the potential for balls and strikes to be called by a machine. While human umpires always will be needed to enforce the rules, what might be the future for robots?

Sporting News asked several All-Stars and found, overwhelmingly, that the game’s best players do not want to see a change, for a variety of reasons. Here is what they had to say.

Corey Kluber, Indians pitcher: I’m sure that if we dug deeper, you’d probably find positives and negatives for it. I think that there is some human element to baseball that’s always been there, that, to me personally, is part of the game with the umpires. Without knowing too much detail about how it works, my gut instinct would be to keep it the way it is.

Clayton Kershaw, Dodgers pitcher: How do we know (the technology is) accurate? I think the umpires do a really good job, and I don’t want to see that. As much as the hitters complain at times about strike zones, the high strike would be called in that box, and that never gets called, so they would have more issues than they think, for sure.

Brad Brach, Orioles pitcher: We’ve talked about it before in the bullpen. I think pitchers would be able to manipulate the electronic strike zone. You look at Zach Britton, our closer, if they had an electric strike zone, hitters would never be able to touch him. He has pitches that he throws, that nick the strike zone and wind up in the dirt. I think they might be able to do something with that, but it’s so difficult.

The umpires don’t get enough credit. They only get the bad attention to them. You don’t realize how good those guys are. They’re like 98 percent-plus, every single day. That 2 percent, where it’s a strike three call that’s a little outside, or they have to throw somebody out because they’re arguing balls and strikes. I think it would be tough to do the electrical thing because guys would throw pitches that barely nick the zone and go so far out, but it’s considered a strike. It would make it really, really difficult for hitters.

(But if it does nick the zone, shouldn’t it be a strike?) Yeah. That’s the argument, but when you have balls hitting the dirt after they nick the zone — like, curveballs especially, being on the plate, hitters would have a really difficult time hitting that. I think pitchers would really like it, but I know hitters wouldn’t.

SN 50: Ranking the 50 best players in baseball

Jackie Bradley Jr., Red Sox outfielder: Certain days you don’t mind it, certain days you do. What everybody wants is, you want consistency. As long as you’re consistent, I honestly feel like people won’t say as much about balls and strikes. (The umpires have) a lot of training, a lot of experience, and even though they may make mistakes and they’re still human, they are, for the most part, the best at their job.

Matt Wieters, Orioles catcher: They’re the best at it as anybody that you can find. I kind of lean away from it because I think if you do put the box with the electronic strike zone up, you’re going to see different kinds of pitchers — which may be a good thing, but completely different from the normal pitcher. You’re going to see a lot of sidearm guys, you’re going to see a lot of guys with big curveballs where the ball is actually bouncing but goes through the box, so you’re going to get a strike. You’re going to lose some of the veteran pitchers who are so good at getting calls. A good thing about baseball is, the more time you put in, you sort of earn a little bit of credibility and a little bit of leeway with some umpires. I think with the strike zone grades, it’s gotten a little less than when I first came into the league, but I think you’ll lose veteran pitchers who know how to throw the ball an inch off the plate or two inches off the plate. That’s part of our game that, as a catcher, I love.

(But isn’t a strike a strike?) As a catcher, you’re going to see a lot of catchers who are just big, strong, burly guys who can hit home runs because you’re not going to have to call a game, not going to have to catch the ball. They’ll just be able to knock it down, pretty much. I don’t think fans want to see catchers back there who are just knocking it down, picking it up and getting a strike call.

Jose Fernandez, Marlins pitcher: I don’t know how that would change the game. Whatever the league decides, I don’t mind. It’s tough because I can’t even imagine that now.

Stephen Vogt, A’s catcher: I don’t think we’re gonna ever go to the machine. It gives feedback to everybody, and it can be a positive tool. Unfortunately, it gets spun negatively a lot, especially on TV and now they can right away, definitively say that was a strike that they called a ball. I think it’s a good educational tool and good feedback for the umpires and feedback for us. Making it widely public, I don’t know how good that is because there’s a lot more that goes into it than just the ball going over the plate. You take away the art of catching, take away the art of manipulating pitches, that kind of thing. It’s a good educational tool.

(Why is it good that catchers can manipulate it?) It’s the human element. This game is becoming too much computerized as it is. I’m old school. You’ve got to have human element in this game because the human element matters. People try to take the human element out of baseball and say that it’s just numbers. It’s not just numbers. A lot of it’s who wants it more. A lot of it is who can get this pitch called a strike. A lot of that goes into it. If we continue to go to the computers and give them more power, you’re going to take away that human element, and that’s what makes this game great.

Marco Estrada, Blue Jays pitcher: It could happen. I know guys talk about it all the time. I don’t know if it would be the right thing. This is one of the longest sports in the United States, and to change it that much, it just doesn’t seem right. I wouldn’t want to turn it into something that’s basically umpired by robots. I like that there is error, there’s human error. It’s going to be there and it’s part of the game. I think it’s something that at times, yeah, it gets ridiculous that guys don’t get calls or guys get too many strikes that should be balls, but it’s part of the game and what makes baseball (great), I think.
