OK

Repeat after me, "it's a dice game"

Random things happen with random randomness when you're talking about dice.

for example as a team the pitchers faced 6003 batters 3008 rolls on hitters cards and 2995 on pitchers cards.
as a staff that breaks down as 50.1% on batters cards...
Strausberg broke down 403 rolls on hitters and 444 on pitchers card....or 46.7% on hitters cards....that made him "outperform" his card....

Sale 581 hitters and 546 pitcher rolls for 51.6% hitter rolls .... he produced about as expected....

this is quite common and adds to the fun....if it was entirely predictable the best math mind would win....
