When I first started betting on MLB in the UK about ten-years-ago I often found myself taking the over on the lowest total on the board because I really had no clue about pitchers, bullpens ERA, etc.
Consequently, as the years have gone on I've found it very hard to get out of the habit of looking at the lowest totals of the day and blindly taking the over.
I finally decided to track the numbers this year, so what I've done is taken the opening line from SBR Odds on any total of 7.5 and lower and taken the over for one unit.
So far this year the system is +8.30 Units and I shall update the record as the season goes on to see if there is any noticeable advantage in blindly taking the over on any total of 7.5 and lower.
Obviously I accept this is a very small sample size and I do intend to carry update this record reguarly over the next five seasons.
