I cooked up a few GIFs of Matt Hobgood's pitches (from our 2010 scouting report
) and noticed some slight differences just watching the clips side by side. I paused each clip at the point of release and took a screen shot, which you can see below.
His curveball is coming from more of an overhand arm slot while his fastball is closer to a 3/4 release. You'll also notice his left leg (to our right) is significantly more bent in the curveball snapshot, and his glove is closer to the ground as a result.
This is taken from a late-March 2010 spring training game, so it's been about 11 months. His mechanics certainly could have changed since then. Still, it's worth taking a look at.
