mariners at home against right handers. The over of 6 or 6.5 there. Nationals at home and under. Rangers at home OVER with jet stream wind that shows blowing in from right field. Start looking more closely at these particular plays and that wind. Get the overnight lines for the rangers totals and research the wind projections. Anyways, my small contribution off the top of my head
I think the general public loves the OVER when the Rangers are at home and the line can get pumped up a full run a lot of times, but like you mentioned, the key is to get it in early.
