By now, most NHL fans - and, especially, Pittsburgh Penguins' fans - are well acquainted with identical twin brothers Liam and Markus Ruck, both of whom were selected by Pittsburgh in this year's draft. And, hey, the Penguins may have a couple of good hockey players in their future there.

But they did something else cool in another sport, too.

Before Wednesday's MLB game between the Pittsburgh Pirates and Atlanta Braves at PNC Park in Pittsburgh, the Ruck twins threw out mirroring first pitches, which tracks with pretty much everything else in their lives.

Well, I guess another difference between them - other than ketchup - is that one throws right, and one throws left!
