Well, since it is tied 3-3 both sides lose because neither is winning - I know it sucks but its the house edge - since it is already on 6 before the 5th - the over loses because it is substantially likely to go over and the under loses because technically it is still under - good luck
At this stage, everything is cancelled....if it stopped now. If it makes it past five but not 8.5 innings then only the ML plays would stand and if it makes it 8.5 or more innings then all bets are in-play....
