Michael Limoncelli, RHP | 5.20.00 | 6-2 / 190

The 6th-round pick from the 2019 class has fully recovered from UCL surgery and as the season progressed in 2021 the velocity and command flashed.

When healthy in high school, Limoncelli pitched comfortably at 88-91 mph, but touched 94, and added strength and delivery work could land him in the low-90s consistently, which is the prognostication for this coming season.

He projects above-average to plus command thanks athleticism and repeatable release and seconds the fastball with an average or better curveball and changeup that’s flashed.

Limoncelli has a chance to pitch at Modesto to start 2022.

Edryn Rodriguez, 2B | R/R | 4.23.03 | 5-9 / 160

Despite a lack of prototypical size, Rodriguez’s short swing generates good bat speed and consistent hard contact. He’s comfortable hitting with two strikes and stays within his abilities, launch hard ground balls and line drives at a high rate.

A natural shortstop, Rodriguez is very good at second and is an above-average runner. He should see the states this season after a .309/.422/.515 slash in 44 games in the DSL last season.

Luis Bolivar, CF | R/R | 2.9.04 | 6-1 / 175

It’s an unrefined skill set, but a promising one, including a chance for average power to pair with the speed and defense.

Bolivar should make his stateside debit this season, and a good showing at the plate could put him on track to see full-season ball before he’s 20.

Cade Marlowe, OF | L/R | 6.24.97 | 6-1 / 210

Marlowe has hit at every level since the Mariners took him in Round 20 out of West Georgia in 2019. There’s too much swing and miss, but he’s still found the barrel plenty and in 2021 slugged .566 on the strength or 26 home runs, 25 doubles, and 10 triples.

He uses the whole field, but he’s learned to take advantage of his pull power.

He projects as an average runner and is playable in center, but fits best in a corner where the pressure to hit is much greater. He’s already 24 and has yet to see Double-A, making it a difficult sell for me, so he wasn’t included in my Top 30, which is a testament to the system depth rather than an indictment of Marlowe.

He can disintegrate my doubt with a strong first half at Arkansas this coming season, at which point we’ll have to consider at least a part-time role in the majors as a better-than-the-original Jake Fraley type.

Charlie Welch, C | R/R | 2.8.00 | 6-0 / 210

Welch is famous for being a pinch hitter extraordinaire in college, sitting behind Cubs 8th-round pick Casey Opitz at Arkansas but slashing .388/.494/.821 in 67 at-bats.

Welch, the Mariners’ 19th-round pick last July, has flashed defensive abilities, but most see him as a potential bat that splits time between catcher and DH, or perhaps learns another position such as first base or the outfield. But the bat looks the part, it’s just a matter of exposing it more as he develops.

He batted .348/.466/.587 in just 58 PAs in the complex league after the draft last summer, but could start 2022 in High-A Everett.

Gabe Moncada, 1B | R/R | 12.17.01 | 6-2 / 175

Moncada has turned bat speed into good power with swing refinements and improved pitch recognition, mashing to the tune of a .359/.500/.560 line last summer in the DSL.

He’s likely stuck at first base, so it’s bat-only here, but he may have earned a shot in the states in 2022 where his raw abilities will be put to the test.

Andrew Moore, RHP | 8.11.99 | 6-5 / 210

No, not that one.

Moore, the club’s 14th-round pick last summer, is a project, but one worth keeping an eye on thanks to velocity up to 98 mph and projectable data on the pitch.

The delivery needs work if he’s to throw enough strikes, and he’s most likely a reliever only, but it’s a power arm that can miss bats in the zone and spin a breaking ball.

Juan Cruz, OF | R/R | 4.30.04 | 5-11 / 155

Cruz is all projection at present, but there’s a chance at some offensive upside with better strike zone judgment. He projects in a corner, is a 55-grade runner, and has bat speed suggesting average power potential down the line.

He needs to get stronger, and I’m curious if the athleticism might not play in center.

German Guilarte, C | R/R | 3.6.03 | 5-11 / 175

Guilarte is a solid receiver with enough arm to stay behind the dish for now, but may not project to have the size to man the position long-term.

There’s bat speed and plate skills in the profile, but his chances hinge on whether or not he can catch.

Aneury Lora, RHP | 3.30.04 | 6-2 / 160

Lora was part of the club’s 2021 international class and hits pro ball a long-levered project with upside. He’s yet to make his pro debut, and was sitting in the mid-80s prior to signing, but with a promising curveball and changeup.

I expect Lora to develop and become a name prospect as early as 2022.
