I'm thinking this is profitable.
27.5% of games are decided by one run. Of those 27.5%, we can expect the favorite to win 57.3% of the time.
That means you'll have a losing bet (favorite winning by one run) 15.75% of the time.
On average, you're laying +136 for a dog, and getting +140 on a favorite. You'll profit $38.83 each game you play and don't lose. When you lose, you're ling $199.17. That's a lay of -512.9281 per game for something hitting 84.25%.
$38.83 X .8425 = $32.71
$199.17 X .1575 = -$31.37
Profit per game = $1.34
Games in a season = 4860
Profit per season = $6533.18
In the long run, you've got the edge, especially if you shop for lines.
Let's backtrack it for last year using Sportsdatabase.
There were 1326 games decided by one run in 2008. Favorites had a 369-294 record in the one run games (55.6%). That means you would have lost 369 games (favorite won by only one run), and won 294 games (dog won by one run) + 717 (dog won by 2+ runs) + 994 (favorite won by 2+ runs). That's a 2005-369 record at (NOTE: DATA IS UNRELIABLE - SPORTSDATABASE TAKES OUT GAMES AT RANDOM IN QUERIES, THIS NUMBER SHOULD BE HIGHER)
-512.9281*369 = -189270.46
100*2005 = 200500
Profit = $11,229.54
