Is there a difference between xFIP and tRA?

By the way I also use B-R for getting stats on the entire league, especially their pitch data (Strike Swinging %, 1st Strike %, etc.)

This has caused a huge gap in his 2006 vs 2009 FIP(3.46-5.84), tRA(4.04-6.33) and ERA(3.56-4.99) that probably doesn’t really pinpoint the underlying skill level very well.

His xFIP over that period has been steady though with a 4.33-4.93 range. I just feel xFIP shows true talent a lot better and FIP, ERA, tRA are much more results oriented which has its uses of course.

Have you guys ever thought of adding xFIP?

Don’t mean to speak for Dan, but I believe he’s talking about how B-R has the cumulative stats listed after each game. So if I look at, say, Yunel Escobar’s game log for June 30th, 2009(on Baseball-Reference) I can see that his OPS after that game was .777. If I then look at the game log for July 24th, I can see that Escobar upped his OPS to .856. So I can contrast those stats, which I like to do from time to time. You guys do have game logs(which include WPA and pLI, which is awesome), but they only list the events of that game; no overall stats.

Or Dan might be talking about something else entirely. But that’s why look at B-R’s game logs, at least.

If tRA uses batted balled data, how accurate is the stat corner version for minor leaguers?

Minor league batted ball data for LD can be very iffy.
