on the upper right there's a box that says "leaders", put your cursor over it and click on "major leagues." Once that comes up click on "Batted Ball" and if you click on "BABIP" it'll sort the players according to it (first time you click it gives you the highest, next click it'll sort them by the lowest). At the top you can toggle between "Pitching" and "Batting" but you'll have to repeat the process of sorting them.
FB/HR% can be deceiving- make sure with batters in particular that you click on them and look at their historical ratio. Low power guys will have lower FB/HR% in general so don't just look at it without analyzing their track records. Ballpark can also affect this but I like to use it a lot when looking at pitchers especially.
