10 Mariners Prospects To Watch Beyond The Top 30

The Mariners Top 30 prospects rankings are up now for Baseball America subscribers, with full scouting reports, BA grades and tools grade projections for all 30 players.

Through the process of narrowing the list down to a Top 30, there are other intriguing names who didn’t make the cut but are worth monitoring, with the potential to jump into the Top 30 in the future. Some of those are players who might be in the upper levels and could see big league time this year, though likely in a limited role, while others are lower-level players still in the complex leagues with more upside but plenty of risk.

Beyond the Top 30, these are 10 prospects to watch in Seattle’s farm system.

Jean Munoz, RHP. Muñoz is a lean, athletic righthander with a 93-96 mph fastball and a plus slider. He doesn’t have a third pitch and his control is below-average, but he has upside as a reliever.

Chris Clarke, RHP. A fourth-round pick of the Cubs out of Southern California in 2019, Clarke reached Double-A last season and was selected by the Mariners in the Rule 5 draft. He’s a big, 6-foot-7 righthander with a 92-95 mph sinker and an above-average, big-breaking curveball that should play in relief.

Juan Then, RHP. Then has struggled with elbow and shoulder injuries but has shown big stuff when healthy. His fastball ranges from 94-99 mph and his slider and changeup both flash above-average, although they are inconsistent. 

Edryn Rodriguez, SS/2B. Rodriguez is a polished player for his age with a good feel for contact, emerging power and reliable defense in the middle infield. He lacks size and his tools are fringy, but his advanced feel for the game gives him a chance to overachieve.

Jimmy Joyce, RHP. A 16th-round pick out of Hofstra in 2021, Joyce misses bats with a 91-94 mph fastball with sink and run and a low-80s slider with good shape. He is a starter now but projects to be a low-leverage reliever.

Jorge Benitez, LHP. Benitez annihilates lefthanded batters with a 90-93 mph fastball from a low arm slot and a high-spin curveball in the mid 70s. His tough angle also plays against righties and gives him a chance to be a low-leverage reliever.

Jake Scheiner, 1B. Scheiner is a smart hitter with big power. He struggles against breaking stuff and swings and misses too often, but his power, instincts and work ethic give him a chance to be an up-down power bat.

Carlos Jimenez, OF. Jimenez signed with the Mariners for $480,000 and spent the last two seasons in the Dominican Summer League, where he flashed above-average speed and defense in center field. He shows a decent feel to hit but little power.

Jose Caballero, 3B/2B/SS. Caballero gets on base with his exceptional plate discipline and is a versatile defender who can play all around the infield. He is also a bilingual speaker who is a good clubhouse presence.

Martin Gonzalez, SS. Gonzalez signed for $1.3 million but hit alarmingly poorly in his pro debut in the Dominican Summer League. He’s a good defensive shortstop but swings at everything, resulting in extremely high chase and strikeout rates.
