So I'm not a sabremetrician by any means, but I was wondering if you guys had any thoughts on how to use a player's split stats for a given day, to determine which player has the better chance of providing more value for a given day.

So an example would be a player like Adam Jones versus Dexter Fowler and who would have a better game tonight with their respective matchups.  

Say Jones is playing versus a lefty, on the road, in a night game while Fowler is playing at home, versus a righty, in a day game.  Is there some formula that you would use to even get a rough idea of who's the better bet?  Would you weigh their past 2 weeks more than any individual split since the sample size is so small?

Any thoughts on how people would approach this would be great.
