you guys want a winning model...here you go: bet against the SF Giants scoring runs.
51 of the last 77 they have scored 3 or less.
27 of the last 36 they have scores 3 runs or less
the last 5 games they have scored 3 Runs or less.
take the UNDER giants runs scored, its normally 4 or at worst 3.5
Good luck gentlemen.
