Marte is just 19 years old and is ranked as the Mariners #7 prospect on MLB.com. He only has one season of statistics as he was 17 in 2019 and then there was no minor league season in 2020 due to the COVID-19 pandemic.
In that one season which was in the Dominican summer league, Marte hit .309 with 9 home runs and an .883 OPS in 299 plate appearances. His MLB.com prospect ratings are 50 for contact, 55 power, 50 fielding, and 55 arm. None of that jumps off the page but he is certainly a solid all-around prospect.
He has the potential to be a decent hitter and sold fielder and because of his good arm he could play third base if the Mariners wanted to partner him with JP Crawford on the left side of the infield. However, with JP Crawford looking like the shortstop of the future it could make sense to trade Noelvi Marte.
He is not projected to be up in the majors until at least 2023, and after losing a full season of minor league baseball it could be longer. So, if the Mariners get into a win-now mode Marte could be out of the door in favor of the present instead of the future.
