  1. How’s his stuff, PITCHf/x-wise, is the next question. If he’s leaving the ball up, or has lost velocity/movement, regression may not occur – the drop in performance could be due to an increase in pulled flyballs, flatter pitches, leaving stuff up or over etc etc.

  2. From the scouting perspective, when Harang started going bad, he had a significant flaw in his delivery. His already short stride had shortened up even further. As a result, his arm wasn’t coming through as far before he was releasing the ball. He lost 3-4 mph, was getting less downward movement (particularly on his change up), and was pitching up in the zone even with his fastball — very uncharacteristic for Harang. He’s built his success on attacking the low end of the strikezone with great frequency.

    All of this seems to match with the results data. Up in the zone with flatter, slower stuff = lots more flyballs and homers.

    He’s been working to get the flaw corrected, and has been improved over the last month. It shows both from the scouting and stat perspectives.

  3. Like Rick said, it seems like whatever he has been doing wrong for the better part of the season is now corrected. He’s been great over his last six starts, with an RA of 2.14. He has also faced some quality offenses during that span, those belonging to the Cardinals, Cubs, Rockies and Astros.

  4. Look at his splits before and after May 25. He threw 103 pitches on May 22, then Dusty used him for 63 pitches in relief on the 25th in that disastrous 18-inning game and brought him back for 73 more pitches on the 29th. It probably just took him a few months and a stint on the DL to recover from the damage Dusty caused.

  5. Matt, I know this is an old post, but I was wondering if you or anyone else has looked deeply into Harang’s Pitch F/X data to see if there is anything potentially wrong with his mechanics, release point, velocity, etc. I plan to do this myself on some level, but I’m not sure I have access to the data behind the Pitch F/X graphs where I could combine starts onto one graph to get the overlay I’d like. Do you have any recommendations? I was thinking of taking a few 2007 starts and pre-5/25/08 (the San Diego relief appearance) starts and comparing them to mid-2008 and 2009 starts. My thought was to take good starts from both periods and bad starts from both periods and put them side-by-side to see if there were anything to see. Jeff Brantley apparently did a pretty good breakdown of his mechanics on TV a few starts ago, but I didn’t get a chance to see it. If you have any advice, I’d love to hear it. Thanks, and keep up the good work!
