Harris allowed just three hits and also struck out 11, reaching that mark -- a career-high -- for the second straight outing.
The 6-foot-4, 175-pound Harris was Toronto's first-round pick (No. 29 overall) in the 2015 Draft out of Missouri State. The 22-year-old works comfortably in the low 90s with his fastball and can reach 95, with some scouts believing his lanky frame leaves room to develop more strength and added velocity. He also processes a slider, curveball and changeup, all of which project to be at least average.

Harris had a rough season debut -- allowing three runs on two hits and four walks in two-thirds of an inning -- but hasn't allowed an earned run in his last six outings and now has worked seven innings in consecutive starts. He moved to 3-0 and lowered his ERA to 0.83.
Harris tossed 58 of his 84 pitches for strikes against the Loons, inducing five ground-ball outs and three fly outs to go with his 11 strikeouts. He turned in a similarly dominant start last week at Fort Wayne, when he struck out 11 vs. just one walk, allowing four hits in seven scoreless frames.
