It just seems like it is a good bet during the week but when it comes to the weekend they score more on Friday-Sunday games....
I had a great night betting no run on Thursday and didn't touch it last night as I had noticed this before.
I haven't gone to do research but look at Thursday versus Friday this past week. 10-5 yesterday in which a run was scored in the first inning...versus 4-9 on Thursday (scoring in first inning).
