Happ shows some promise. He is six-feet tall, lefthanded, and throws a 90mph fastball. He has consistently posted good minor league numbers and looks like he might translate it to the major league level. Happ owns a tight slider that he uses often. He likes to try and go inside on RHs with it, burying it at their ankles, or throw it away from LHs. Happ will also show a changeup to RHs and mix in a very slow curveball. 8/7/08 CSJ

*fastball(87-92), slider(80-84), changeup(79-82), curve(69-70)

* His velocity is still consistently in the high 80’s. Last year and the year before there were reports of him hitting 91-94, but according to MLB Gameday, which is the most accurate reading you’ll find, more accurate than the TV guns, he was 87-89 the entire night. What makes that seem faster is the way he hides the ball behind his back, and the fact that he’s very tall and lanky, meaning the ball gets on the hitter quicker because it’s released closer to home plate. This should also be a lesson, don’t always believe the velocity numbers you hear from scouts, they have a reason to embellish at times.

* Happ leaned very heavily on his fastball and changeup. By my quick count, this was his breakdown

Fastball: 57 (61.3%)
Change: 26 (28.0%)
Slider: 9 (9.7%)
Curve: 1 (0.01%)
