Organization Prospect Rankings

Track Record: Then signed with the Mariners for $77,000 when he was 16 and quickly emerged as one of the top young prospects in their system. The Mariners traded him to the Yankees in 2017 in a deal for reliever Nick Rumbelow, only to re-acquire him two years later in exchange for Edwin Encarnacion. Then returned from the coronavirus shutdown with a star turn at instructional league, but he struggled at High-A Everett when minor league play resumed in 2021. He went 2-5, 6.46 in 14 starts and was limited to 54.1 innings by shoulder tenderness.

Scouting Report: Then has plenty of stuff, but the results haven’t followed. His lively fastball sits 94-97 mph, touches 99 and plays in the strike zone. His slider is an above-average pitch that is his best secondary at times, and at others his above-average changeup is the better pitch. Then’s biggest issue is consistency. He has a hook in the back of his delivery that affects his ability to get to his breaking ball and his below-average control prevents him from effectively navigating a lineup multiple times.

The Future: Then’s pure stuff excites evaluators who think he will be more effective in short stints out of the bullpen. He may make that switch to relief as soon as 2022 at Double-A Arkansas.
Fastball: 60. Slider: 60. Changeup: 55. Control: 55.

TRACK RECORD: Then first signed with the Mariners in 2016 and was traded to the Yankees one year later. The Mariners reacquired the lanky righthander in 2019 in a trade for Edwin Encarnacion, and Then reached low Class A by the end of that season. Then spent 2020 at the Mariners’ alternate training site before reporting to Arizona for instructional league.

SCOUTING REPORT: Then added 10 pounds of good weight prior to spring training and dropped his arm slot to a more natural position. Those changes resulted in a big uptick in his velocity. Then’s plus fastball sat 96-97 mph in the fall and began touching triple- digits, up from his previous 92-96. It’s a four-seamer with tail and sink, but he can also manipulate it to generate average movement to his glove side. His hard, sharp slider also added power to flash plus at 87-91 mph, and he has a good feel for an above-average changeup at 88-91 mph with deception and a good bottom. Then uses a low three-quarters slot with a smooth arm action and a clean, repeatable delivery that yields above-average control.

THE FUTURE: Then has the attributes to be a mid-rotation starter, but he could also thrive in a late-inning bullpen role. He will likely start 2021 in high Class A.
TRACK RECORD: The Mariners would have been wise to purchase a round-trip ticket for Then when they traded the lanky Dominican to the Yankees in late 2017, as he headed back to the organization last year in the trade involving big leaguer Edwin Encarnacion.

SCOUTING REPORT: Then shows confidence on the mound, attacking hitters with his electric stuff. His fastball sits 92-93 mph, touching 96, and there's room on his frame to add strength. His heater comes out effortlessly and with late action. Still a work-in-progress that projects as an average pitch, Then's 80-84 mph slider has late break and 10-to-4 movement. The 83-88 mph changeup is a hard pitch that flashes plus, but he doesn't use it much. He throws his fastball for strikes but needs to get more swings and misses over the plate from his secondary pitches. He repeats a high-three-quarters delivery.

THE FUTURE: We'll have a better idea about Then's future projection after more time in full-season ball, but for now mark him down as an intriguing starting pitching prospect.
Track Record: The Mariners liked Then’s quick arm and projectable frame and signed him out of the Dominican Republic for $77,000 in 2016 before flipping him, along with lefty J.P. Sears, to the Yankees for reliever Nick Rumbelow. He made his Yankees debut in 2018, posting a 2.70 ERA in 11 starts in the Rookie-level Gulf Coast League.

Scouting Report: Then boasts a three-pitch mix that starts with a low-90s fastball that touches 95 mph. The pitch features running and riding action out of an overhand slot. He backs up his fastball with a 78-82 mph curveball with hard, downward snap. The pitch is inconsistent but projects plus with repetition and development. He also throws a mid-80s change that shows hard sinking action and could be average in the future. There are some concerns about his somewhat straight fastball, which is exacerbated by his lack of size and little remaining projectability.

The Future: Then has a chance to stick in the rotation as his arsenal develops, but the bullpen is also a possibility. He should pitch at one of the Yankees’ two short-season affiliates in 2019.
Then was signed out of the Dominican Republic by the Mariners as a pitcher who, with a quick arm and a slight frame, had a good amount of projectability remaining. He was dealt to the Yankees in the 2017 offseason with lefthander J.P. Sears in exchange for righthanded reliever Nick Rumbelow as New York cleared space on its 40-man roster. He had a stellar opening season as a professional, allowing just 50 hits in 61.1 innings in the Dominican Summer League. He also experienced a velocity jump, moving into the low-90s with his fastball and touching as high as 94. He backs it up with a loose, 74-78 mph curveballt that he needs to tighten and work to land in the strike zone more frequently. He also has an 81-86 changeup that's ahead of the curveball in both development and ability to throw the pitch for a strike. His delivery calls to mind Mariners closer Edwin Diaz, but he needs to gain strength to be able to repeat his motion. Added muscle will help him land on-line more often and keep from falling off the mound on every pitch. He's likely to start the year in extended spring training before heading to either one of the two Yankees half-season affiliates in mid-June.
