View Draft Report
Miller has been one of the best pitchers in the history of Millersville baseball, and he helped guide the Marauders to a Division II World Series runner-up finish this spring. Over three years, he struck out 215 batters and walked just 32. Miller's prospect balloon began to inflate with a strong showing in the Cape Cod League as a rising junior, and he followed that performance up with an exceptional junior spring, in which he went 11-1, 1.61 ERA. Miller pitches off his fastball, which works mostly at 88-91 mph and touches slightly higher. He also shows a short slider that grades out as a near-average offering. Miller keeps the ball off the heart of the plate and shows solid control. He has a physical 6-foot-4, 195-pound frame and a clean delivery, giving scouts the impression that he could be a starter at the next level.

Organization Prospect Rankings
The Mariners discovered Miller because they had kept an eye on the Division II Pennsylvania State Athletics Conference after successfully finding Mercyhurst (Pa.) righthander Dan Altavilla in 2014. Miller went 12-2, 1.42 with 115 strikeouts and 13 walks in 107.2 innings in 2016 to lead Millersville (Pa.) to a No. 1 ranking in D-II and a national runner-up finish. He tossed a complete game with five hits and one earned run and seven strikeouts in the opener of the D-II World Series and was drafted by the Mariners a week later, signing for $250,000. He kept up his dominance in pro ball, recording a 2.72 ERA and 51-to-7 strikeout-to-walk ratio in 56.1 innings at short-season Everett. Miller works off an 89-91 mph fastball that gets up to 93 with an elite spin rate, while his 80-83 mph slider grades as a plus pitch that also features excellent spin and a high whiff percentage. His curveball and changeup are currently below-average but project to average with further development. Miller's balanced four-pitch mix, poise and durability project him to a back-of-the-rotation starter, and he has a chance to skip low Class A Clinton altogether and begin 2017 at high Class A Modesto.
