62. Peterson was a rangy 6’6″ high school senior ranked highly that chose to go to college instead after breaking his leg his senior year and missing time, causing his draft slot to fall. He’s had a good career with Oregon, but most importantly, he’s filled out that frame to a 240-ish pound monster that has been dominating college hitters this season, including multiple 17+ strikeout games. At his size, he has a remarkably repeatable delivery with a heavy low-90s fastball, a plus slider, a curve that rates average, and a change that some grade as his best overall pitch. Peterson should make it to the majors quickly, and the Mariners will be more than happy to keep the Oregon product in the Northwest.. LHP. University of Oregon. David Peterson. 17. player
