Most of the Mets' high-impact prospects are in the lower levels of the minors, but they have a handful of players who can help as soon as 2019 or 2020, including...
Andres Gimenez
Gimenez, 20, is projected to be ready to reach the big leagues in 2020. He's currently the organization's top prospect and ranked the 58th overall prospect in all of baseball.
I like that he's "unassuming," as MLB.com wrote this past winter. He's a small kid, which makes him look inexperienced and not ready for prime time. But talk to any scout, reporter or executive that has watched him and they all agree he has terrific tools on both sides of the ball.
