Back at the start of 2009 – he’s thrown three innings since then – Beyond The Boxscore posted a Prospect f/x for Mason Tobin. A couple of highlights:
First and foremost, Tobin was throwing hard – fastballs came out of his hand anywhere from 94.5 mph to 97.3 mph. His off-speed pitch was slurvey, checking in at 76mph with good lateral break.
Tobin’s slurve has some nice lateral spin movement on it. He throws from a fairly low arm slot, and as mentioned above, isn’t a slider or a curve. Given his fastball velocity, you’d expect Tobin to throw a slider in the 80s, not the 70s. Tobin also released the pitch a little higher than he did the fastballs.
Tobin looks good, throwing very hard with good movement. I wonder if he has another pitch that he didn’t use (a change-up, perhaps?), but the fastballs and the slurve should work nicely in relief.
