I'm not saying Parra is fixed yet, but what I am saying is that I don't believe he was unlucky for a season and a half and now he's suddenly lucky which is leading to better results. There's nothing wrong with your assertion that it wasn't luck. It might actually be more likely that Parra's true BABIP (or SLg against or whatever you want to use to measure effectiveness) trully is well above average. The thing about statistical uncertainty is that you just can't PROVE it conclusively, using sample based statistics. A true .320 BABIP pitcher could pretty easily have a .360 BABIP for a season and half ONLY because the coinflips went against him. Or it could be because his location stunk. Now, if you KNOW that Parra is consistently thowing his pitches in a location that on average, causes a worse than average results, that's altogether different. More than a couple of studies have verified the pretty obvious connection between location and pitch effectiveness. Here's one: http://baseballanalysts.c...9/07/can_pitchers_co.php Like cwolf, I am quiet skeptical that you have accurately kept track of Parra's pitch locations, though. I don't know how anyone could, just by watching games. Here is Parra's pitch f/x data by starts: http://www.fangraphs.com/...010&date=2010-06-18&dh=0 Even having all the data in front of me at one time, it's hard to make any objective observations. I would need to dump all the raw data intoa spreadsheet and do a study. But apparently, you've apparently stored all that in your head and came to a definitive conclusion? I think you are WAY overestimating your observational abilities. Thousands of pitches! Thousands of results! The notion that "all you have to do is watch him pitch and you know" HAS to be just starting with the results and working your way backwards. That or you are Rainman. Also, I think it's a lot more complicated than just looking at pitch location, anyway. Pitch velocity, break, location, sequence, deception, etc... I don't think anyone has claimed to be able to understand everything that goes into understanding the art of pitching. "Basically, luck is garbage, the end." To apparently completely reject the whole concept of luck in sports is pretty silly. It's like rejecting that that water is wet and the sky is blue. I think you just don't find the non-deterministic nature of sports to be emotionally satisfying so you try to dismiss it. If you flip heads, it's because you were supposed to flip heads?
