Jeter Martinez is a fantasy baseball SP prospect sleeper and minor leaguer to know. Read our MLB prospects outlooks for fantasy baseball rookies and call-ups.
PROSPECT: Jeter Martinez, SP, Seattle Mariners
ANALYSIS: The Mariners signed Martinez out of Mexico this January as one of the top-rated available players on the international market this season. He was the top-rated player from Mexico in all rankings.
The 6'4" Martinez has long arms and generates additional difficulty to hit as he comes over the top with his delivery. So far, Martinez has made three starts in the Dominican Summer League, tossing 13 2/3 innings, allowing just one earned run with a 19/3 K/BB rate.
Martinez works in the low-90s now, but he has the frame to add good weight and definitely add velocity. He's also shown an impressive feel for multiple offspeed pitches.
VERDICT: Martinez is a long way off, and you'll not ever see me recommend a DSL pitcher as a fantasy add at any dynasty level. That said, the feel that Martinez has of his pitches at his young age as well as the frame to continue adding make him one to keep in the back of your mind.
