Players getting angry towards an umpire is synonymous with baseball. And during the Arizona Fall League, it's no different ... even if you're arguing with technology.

During a Tuesday fall league game, Giants outfield prospect Jacob Heyward, the younger brother of Cubs outfielder Jason Heyward, was ejected after striking out on a call made by a robot umpire:

Looks low and inside, right?

But if you scroll to the next photo of the Instagram post, the pitch tracker shows it was, indeed, a strike. 

So who (or what) was Heyward yelling at if he was unsatisfied with the call? Heyward appears to claim his displeasure wasn't with the home plate umpire -- who simply was relaying the call from a computer system -- but he was ejected nevertheless.

This year, the automated ball-strike system (ABS) has been implemented to use at all games being played at Salt River Fields in Scottsdale, Ariz.

The independent Atlantic League first tested the technology, which includes a real-life umpire still manning duties behind the plate. The ump receives communications via an earpiece that's connected to an iPhone, and then relays the call from the TrackMan computer system.

Yes, it's complicated.

Despite Heyward's reaction, the data shows the pitch was a strike. And even if this is the case from now on (MLB will sometimes adopt these "experiments" down the line) the human element of emotions still will always come into play.
