Matz, a Mets fan from Stony Brook, was drafted in 2009 and immediately had his career thrown off track when he needed Tommy John surgery in 2010.
In 21 starts for Low-A Savannah last year, he went 5-6 with a 2.62 ERA, allowing 38 walks with 121 strikeouts in 21 starts.

He was the only pitcher I saw to throw his session alone. It was done under the watchful eye of owners Fred and Jeff Wilpon, with a cameo from Sandy Alderson. Matz threw mostly fastballs and, according to my eyes, appeared to be nice easy cheese. He has a smooth left-handed delivery and throws hard for a player not overwhelmingly large in stature.
Matz is worth keeping an eye on. The organization doesn't have a lot of left-handed arms, especially guys who throw as hard as Matz. He's a starting pitcher. He's got really good stuff. However, a veteran scout who watched Matz last year told me he believes the kid could be a very valuable relief pitcher one day, similar to a Craig Breslow. I bet he starts his big-league career in the bullpen, probably during 2015, then transitions back to the rotation when there's a need.
