The San Francisco de Macoris, Dominican Republic native fired 61.1 innings over a span of 13 starts. Then made a strong impression in his first season in professional baseball by collecting 56 strikeouts while just permitting 12 walks. He pitched to a 2-2 record with a 2.64 ERA and .220 opponent batting average against.

Scouting Report

Then is a 6-foot 1-inch tall, 155-pound right-handed pitcher. He throws his fastball in the low-90s and possesses two secondary pitches, a changeup and breaking ball with a smooth delivery.

There is a lot of upside in Then, he has the potential to be ranked highly in the organization depending on how he develops. MLB.com has ranked Then as the 28th best prospect in the organization and given him a 45 overall, 55 fastball, 50 curveball, 50 changeup, and 50 control grades. Because Then is still very young, expect him to add more velocity as he matures and becomes more consistent with his delivery.

As MLB.com writes, “Once Then matures physically, he could have three solid or better pitches in his arsenal. He had no problem throwing strikes in his pro debut, another reason to think he might develop into a mid-rotation starter.”

2019 Outlook

Then will be 19-years-old when the 2019 season begins, he will likely spend the season with the Pulaski Yankees of the Appalachian League after seeing time back in extended spring training.
