Is there a good reason for this?

My 1992 Yankees team is 14-31 in one run games, that's a winning % of .311.
In games decided by more than one run we are 73-26.  That's a winning % of just under .740.

Really?  

We are 9th (out of 24) in runs scored and 1st in runs allowed.

My bullpen is pretty solid.

I have scored 212 more runs than my opponents.

Anyone have any ideas why my team is so much worse in one run games?

Guess: You win a lot of blowouts and make your losses close.

I have won 6 by 10 runs.  None more than 12.

I basically agree, but I'd put it another way: your run distribution is likely off.  This is most likely the result of "living off the three-run homer"  If you want to be scientific about it look at the frequency of your run support and runs allowed. 

Since your team was 30 games over .500 at the time of your post, I wouldn't lose any sleep over it and just chalk it up to bad luck, especially if most of the 1 run losses were 9 inning games as opposed to extra innings where you could adjust your late inning pitchers to have more of an effect.
