  1. Great start for the kid. Baltimore is very excited to have such a young player turn in to a future ace.

  2. He mixed his pitches really well, and that may have helped him get more strikes with his change-up than the movement on it would have implied. As a fan watching the game, I have to say that I was totally comfortable with him on the mound. Eve when he got into a couple of jams I just felt like he’d get out of them and it wasn’t a big deal. That might have a lot to do with his polish.

    Once Bergesen comes off the DL, they O’s rotation may be Bergy, Matusz, Tillman, David Hernandez, and Jeremy Guthrie. That should be pretty exciting to watch.

  3. Erik,

    Often you hear scouts/evaluators describe pitches as having “late break”, and I’m wondering if pitch f/x provides information on this (or if such a thing actually exists). For example, 2 pitchers throw similar 90mph fastballs that break 5 inches into a right-handed batter — is it possible that pitcher A’s fastball starts its break at 40′ and pitcher B’s begins at 45’? Does pitch f/x quantify this sort of thing? Or is it only a function of velocity (a pitcher who throws harder but has similar break has a sharper break since the ball needs to move more in less time)?

    It seems to me that pitch break is a result of the spin imparted on the ball by the pitcher, which only diminishes after the ball is released. So on one hand I’m inclined to believe that there is no such thing as “late” or “early” break (only “more” or “less”), but on the other hand I can count what I know about physics with three fingers (thanks Newton) and what I understand about pitch f/x and pitching mechanics on the other two (they exist).

    I apologize if I’m a mile or two behind the curve on this, but I’d appreciate your insight.
