Miami Marlins: 7 Top Prospects that could make Full-Time MLB Debut in 2021

3. 1B Lewin Diaz – Miami Marlins #5 Prospect

Off to a similar hot start to the Triple-A season as Sanchez, momentum continues to build for Miami Marlins 1B prospect Lewin Diaz.

Diaz is listed as the Miami Marlins #5 prospect according to MLB Pipeline, and is regarded by most as arguably the Marlins first baseman of the future. Diaz has continued to impress throughout his time in the minor leagues, and now has himself on the verge of the big leagues full-time.

Diaz originally signed with the Twins back in 2013, but was traded to the Marlins in 2019. Diaz struggled initially after he was traded to Miami in 2019 only hitting .200, but the power potential he sports was evident as he hit 8 HRs in 31 Double-A games.

Speaking of that power, that is exactly the kind of hitter that Diaz is. Not only is Diaz a strong defensive first baseman, but the 6’4 24-year old displays a powerful left-handed swing that allows him to drive the ball to all parts of the field. Also evident by 27 HRs across three different teams during the 2019 season, it’s clear that Diaz has big-time power potential.

We’ve already seen Diaz make his MLB debut during the 2020 season where he went 6/39 at the plate with 3 RBIs. While the numbers won’t blow you away, Diaz impressed enough both offensively and defensively for the top prospect to earn a roster spot for the 2020 NL Wild Card Series, despite not playing in a game.

Similar to Sanchez, Diaz is off to a hot start in the Triple-A season where he is 4/9 from the plate with 2 HRs and 7 RBIs. If he keeps this up, Diaz may soon be manning first base with the big league club in due time.
