From MLBTR: "As for the Rays, they picked up the younger, 19-year-old Martinez who now ranks as their No. 21 prospect at MLB.com and Baseball America as well as their No. 31 prospect at FanGraphs. The lack of a minor league season makes it impossible to really evaluate the younger Martinez’s 2020 season. That said, he posted a .311/.388/.437 slash through 233 plate appearances back in 2019 and adds some depth to the lower levels of one of MLB’s best farms." If he ranks #21 or #31 in the Rays system, he would probably be close to the top 10 in our system. He was 19 in BA, 28 on MLB Pipeline (this is probably an obsolete ranking if he's 21 for the Rays), 22 on Fangraphs.
