David Peterson

Peterson was a Top 100 prospect out of a Denver high school thanks to a projectable 6-foot-6 frame, ability to sink his fastball that reached 91 mph and flashes of above-average changeup and slider. A broken right fibula delayed the start of his prep senior season, and the 28th-round pick (Red Sox) didn't sign, instead heading to Oregon. He proved durable in his first two seasons and pitched for USA Baseball's Collegiate National Team last summer, but Peterson didn't take off until 2017, when he hit it off with new pitching coach Jason Dietrich. Peterson was leading the country in strikeout-to-walk ratio in early May and had six double-digit strikeout games, including 17 against Mississippi State and 20 in late April against Arizona State. Peterson has improved his fastball velocity (up to 94 mph early in games) and command this season. He pitches at around 91 mph. His quieter delivery features better direction to the plate this year and a bit more deception, eliciting swings-and-misses from his fastball. His slider earns plus grades from some scouts, and at times he'll back-foot righthanded hitters with it all night until they adjust. Then he can locate an average curveball to mix things up, and scouts like his above-average changeup, though he doesn't use it much. One Pac-12 coach called it his best pitch, with plus tumble and fade, and it allows Peterson to go arm-side with his fastball and change, then glove-side with the slider, slicing up the plate and flummoxing hitters. Peterson stays out of the middle of the plate, pitches with angle and gets groundballs when he isn't striking out loads of hitters. He has solid athleticism that allows him to repeat his improved delivery, even as he's filled out physically from 213 pounds as a prep senior to a listed 235 at Oregon. Peterson had pitched his way into the first round.
