There are a couple things I can think of right off the bat that are instrumental in determining ERA that aren't considered in those three stats:

-- unearned runs (since they don't count towards the ERA)
-- innings pitched (since visiting teams don't pitch the same number of innings in a loss)

If those two things, along with the earned runs, are equal then the ERA will necessarily be equal as well (unless I'm having a brain cramp).

Batting average is more clearly coincidental... even earned runs are scored through a variety of ways, and percentage of hits to at bats is just a slice of measuring them.

Sorry out of time to try to tie this to basketball.

SportsCenter had an interesting comparison, showing
that the Astros and Cards have an equal number of runs
(29), batting average, and ERA (4.80) over their 6
games so far.

Does anyone think this is pure coincidence, or could
it be that if their runs and batting avg are the same,
then their ERAs must surely also be the same?

Can we draw statistical parallels in basketball? An
easy one would be TOs vs TO's forced. However, I'm
wondering if something more in-depth can be drawn out.
