tRA now on fangraphs.com

I used to get it from statcorner.com, and still might, I'm not sure. The tRA on fangraphs will be a little different then on statcorner, because they use different batted ball info, and different park factors.
By the way, tRA is not on a ERA scale. To get it to a ERA scale (tERA) multiply the tRA by .92.
Here is some info on tRA. (Read the comments; some of them have more info)
