Longtime aces Yu Darvish and Justin Verlander have pitched against each other on the field and online. They've had some good battles. However, a personal fight developed between these two competitors. Their ongoing feud goes back to April of 2018, when Justin Verlander fired some shots on twitter:

Darvish got him good. Now if you are new to CubsDNA culture, allow me to explain.
