real good profile of Martis by Harry Pavildis at HBT:
Martis is essentially a three-pitch pitcher. Or two, or five. He rarely uses his sinker, but his slider may be two or three different pitches:
- Change (CH) usually about 80mph, sinks and tails like his two-seamer, but 10 mph more slowly; three-finger grip and others (?)
- Four-seam fastball (F4) sits at 92 mph, tops out below 95—which isn't overpowering, but it is his bread-and-butter
- Two-seam fastball/sinker (F2) rarely used and only against left-handed hitters
- Slider (SL) ranges from 75-85 mph, probably runs the gamut from slutter to slurve
Batters whiff at Martis' change 47% of the time, which is amazing. They whiff at his slider 30% of the time which is above league average.
