ABS powered by Team Mobile and a call that was a strike.

A little sinker up and in.

Has been confirmed.

That was a bit of baseball history being made last night in San Francisco.

The first regular season challenge using Major League Baseball's new ABS system,

that's automated ball strike. In every major league ballpark now,

new camera technology will track the precise location of pitches. Teams can challenge up to two

baller strike calls made by an umpire and a nine-ending game. It's the start of a new era, so on this

opening day, let's bring in Dan Evans, a former general manager of the

Los Angeles Dodgers. He's also had key roles with four other teams most recently as a scout

for the Toronto Blue Jays. So Dan, help us understand us. Give us the ABCs of ABS here. How does this work?

Who can make a challenge and when? First of all, John, just what we need in our life,

another acronym that we have to look up the first time. For the fans, the key thing is

the game is trying to get it right and working on getting it right as well as possible.

What this does is twice a game, a batter, catcher, or pitcher can ask within two seconds of a pitch for a clarification is the call overruled or does it stand?

There's going to be real alacrity to this.

And I think the key to know for the fans is that a manager, a coach, someone in the

ballpark can't really influence the batter, the catcher, or the pitcher to ask for the appeal.

It's only those three. Don't just think some managers are going to figure out a sign to get one of

those three to make a call?

I wouldn't be surprised, but I think there'll be penalties. What we've already learned, John,

is the pitchers and the catchers, actually the catchers and the pitchers are better at this than the hitters are.
