The Pregame Results Archives for Over/Under Totals show large variations in Runs. Example:
8/20/2015 8:10:00 PM MLBTotal (Houston/Tampa Bay) Under 0 - 1 u 7.0 (-115) W 100.00
8/20/2015 8:10:00 PM MLBTotal (Houston/Tampa Bay) Over 1 - 0 o 3.5 (-110) L -110.00
Why is the O/U for one player 7 and 3.5 for the other? It doesn't indicate Team or 1st 5 inning Totals. The only Pick options I'm aware of on the site for baseball are:
Run Line, ML and O/U.
This large Run difference appears frequently and I'm certain that the Run total didn't move that much with LV oddsmakers.
If these low numbers are real, please let us where we can wager on these Totals.
