Homering on first MLB pitch

There have been 30 players in history to hit a homer on their very first pitch in the big leagues. Two of them are Cubs, including the most recent one to do it, Willson Contreras in 2016. (I was there for that game--it was Father's Day)

Of the 30, 15 did it last century, 15 have done it since the turn of this century.
