From BtBS article "2010 Rule 5 Drafted Pitchers in the Majors: Pitch Analysis": Nathan Adcock was taken by the Royals with the 5th pick in the Rule 5 Draft and has been used as a long reliever in the Royals' super young bullpen, though he has made two short starts (one okay, one short disaster). His numbers have been less than impressive: he's put up a 4.55ERA/5.18FIP/4.13xFIP line, though some of that is due to really bad luck on Home Runs.
Now these pitches are more impressive than Paterson's and show some potential. Adcock's primary offering, the two-seamer, gets pretty damn good sink and still manages to average above 90MPH. And as such, it does indeed have good GB numbers against both types of batters. Adcock's change-up has similar movement to the two-seamer (with a slight bit more sink), but a 4-5 MPH gap from the two-seam fastball. He also seems to throw the pitch to both righties and lefties, and in a really small sample size has been somewhat successful with this infrequently used pitch.
Adcock's other pitches are more hit or miss: the four-seam fastball doesn't have great movement; it's basically average (as John Sickels described above). His Slider has pretty good velocity, but really doesn't have a huge amount of horizontal movement, though its horizontal movement relative to the fastballs could make it potentially a really good pitch. The Curveball is more of a slurve (there's little drop, and all horizontal movement), and really all it has going for it is velocity.
Regardless, Adcock is one to keep an eye out for. He has a starter's repertoire, a main pitch that has some pretty good properties, and good velocity on his secondary stuff to make up for less impressive movement.
