These are not my systems. They were posted here by someone back in March....
Bet on any underdog that has won at least 7 or more of it's last 11 games......Bet against any fav that lost 7 or more of it's last 11 games.
Take the average offensive runs scored for the last 3 games. If the dog has a 2 run advantage over the fav, then you have a live underdog with hot bats.
