Sports: why is Pittsburgh baseball team called the Pirates?

Self-tutoring about American sports history: the tutor looks up how the Pittsburgh Pirates came to be so-called.

In my experience, sports people are clever in subtle ways. Therefore, I was sure the name Pirates would have an interesting story behind it, which it does.

Back in 1891, the Pittsburgh Alleghenys baseball team hired talent from other teams in a way called “piratical” by the teams whose players they lured away. The name was so compelling, the Alleghenys adopted it, becoming the Pittsburgh Pirates in 1891:)
