Mariners set to sign international prospect Jeter Martinez

Reports indicate the Mariners will announce the signing of pitcher Jeter Martinez, rated the 42nd-best international prospect in baseball.

Sunday represented the start of the 2023 international signing period. As we wrote, the Mariners confirmed the signing of seven players including shortstop Felnin Celesten, the second/third rated international prospect in baseball.

In this respect, Mariners fans will be excited to learn of reports indicating another highly-touted international prospect also set to join the organization. As per Jesse Sanchez and Daniel Kramer of mlb.com, the signing of pitcher Jeter Martinez will apparently be announced at some stage in the coming days.

Martinez is rated by MLB Pipeline as the 42nd-best international prospect in baseball. According to sources, his deal will be worth $600,000 pending finalizing the details.

Projectable talent

The 16-year-old is already 6 foot 3 and 185 lbs, with his projectable frame bringing to mind Mariners and MLB Hall of Famer Randy Johnson. Scouting reports indicate he will be a starter as long as he continues on his current trajectory.

Martinez’s fastball is currently around 90 mph and should only improve as he continues to grow and add strength. There is already some sink in his fastball, and he creates some deception with his arm angle.

As per mlb.com, there is also some fade to the righty’s changeup and a sharp bite to his curveball, but both are works in progress. He already has good command of the strike zone, along with an instinct of how to attack hitters.

Best prospect in Mexico

Martinez is considered the top player from Mexico in this international class, which is impressive in itself. He has experience playing in the showcase circuit in the United States.

Martinez also trains with Showtime Top Velocity. A number of teams have shown strong interest in him, but it seems like the Mariners are set to win out and claim an impressive coup.

Frankie Thon Jr. is the Mariners’ Director of International Amateur Scouting. Speaking on Sunday about the start of the international signing period, he said:

“To witness the moment that these young players, from diverse countries and backgrounds, achieve their dreams while taking that first step towards their ultimate professional goal…it’s something that we as a staff will surely never take for granted.”

Pending official confirmation of the signing, what is your opinion of Martinez? Further, what is your take on the Mariners’ international signings as a whole so far in 2023? Let us know in the comments section below.
