Bet365 3 way handicap betting on baseball??

[shanek]

Can you please clarify how the 3 way handicap betting works for baseball.
Example: pit +3.0 1.86
Tie-pit +3.0 6.50
Cin -3.0 2.50
If someone bets on Cin -3.0 2.50...does this team need to win by 3 or 4 to win the bet? What if they win by 3, is it a push and do you get your money back?

Thank you

Those arent the odds im seeing on site?
on 3 way , -3 means a 4+ victory, 3 tie means exact 3 victory, and +3 means the dog can lose by 2 or better it.
