Washington’s 7th round pick last year, Tetreault started his first full professional season with Class A Hagerstown before a midseason promotion to the Carolina League. He’s flashed strikeout ability and the control to remain in the rotation long-term.
Tetreault utilizes a simple one-step semi-windup into a letter-high leg-lift and throws from a three-quarters slot. He turns away from the hitter and has deception in the delivery’s finish. His fastball sits in the 90-to-92 mph range with the ability to reach back for an occasional 93-94 mph when needed. It has consistent sink and flashes sink and slight cutting action at best. Tetreault has more control than true command within the zone, often working over the middle of the plate and struggling to paint corners. He throws a true cutter in the high-80s with sharp, late tilt. He commanded his cutter better than his regular fastball in this look, nabbing low corner strikes to both righties and lefties. His upper-70s changeup and curveball (74-to-76 mph) aren’t as developed, and he’ll tip both pitches at times.
Tetreault will get every chance to remain a starter given his large frame and potential four-pitch mix. I love his projectable and athletic 6-foot-5 frame, as well as the way he attacks hitters on the mound. He’s still raw and there’s risk to the profile, but the ceiling could be a backend starter. If the secondary pitches don’t sharpen up, his fastball/cutter combo ticking up in the ‘pen is an interesting fallback.
