nippert had tommy john surgery last year, but seems to be fully recovered and pitching well like he did in 03.
his fastball is in the low 90's and he has a very good curveball.
not sure about his shot at the rotation next year. the dbacks shouldn't rush him too much cuz of his the surgery...and you never know who they will bring in next season...there is a russ ortiz out there every year.
he might be the best pitching prospect for the dbacks right now.
