Just figured I would throw this out there but I noticed that yesterday's pitchers started on at least 6 or 7 days rest. That could have contributed to strong first inning starts that would favor no scores in the early innings.
I am also finding that when there are changes on the money line, the win tends to parallel the move. ie last night money moved on the SF game in first inning for a no score. I have seen this with other games as well. So maybe a good idea to watch for the moves. The lines usually don't move at BETUS but when they do, it may be worth noting.
Good point on the Betus deal, but I grabbed the wrong quote.
Please keep us informed of these moves when you notice.
