A collision at first base led to a spat between the Cardinals vet and a Brewers player — and a fiery postgame rant.

St. Louis Cardinals star Willson Contreras had a secret message for his teammates, but it won't make Brewers fans happy.

To support his teammate, Rhys Hoskins voiced his displeasure loudly from the bench. In a postgame interview, Contreras was asked about the incident, and his fiery NSFW response went viral on social media. While Willson Contreras never named the player, it was evident that he was taking a jibe at Rhys Hoskins.
