​In this episode of "Professional Athletes Behaving Badly," we have a case study on Twitter usage.

Houston Astros third baseman Alex Bregman is ​not having an amazing season at the plate. He's hitting .256 with eight home runs and 27 RBIs. The team has strong position players all around but lacking pitching depth, leading to Bregman's name circulating in trade rumors.

One Astros fan made note of this on Friday.

What happened next requires a certain lack of social media understanding - Bregman decided to reach out to @AllenH83 with a direct message. Not a particularly nice one either.

Guess he never heard about screen shots. 

Throughout the conversation, Allen manages to hold his own, responding as respectively as possible.

Bregman did not take the same route. Reaching out isn't always a bad thing, but it is when the first message is an insult of a fan's baseball knowledge.

Then, he decided to call him "flees on the nut sack of society," which seems like a disproportionate reaction to almost anything, before concluding with the classic "keep my name out of your mouth." 

That's going to be pretty difficult for him to do, since you just gave him the biggest talking point of the Astros during the All-Star break.

Trade rumors can be uncomfortable for players, but that doesn't mean they should randomly lash out at fans. If the Astros weren't motivated to trade Bregman before, perhaps they are now. Either way, not a great look.
