Seattle Mariners Ranked 34 Prospects as Top Talent

Mark J. Rebilas of USA TODAY Sports was also present during this event.

However, other times the issue lies within. So where would that leave us now? Essentially we don’t know.
Below is an analysis of Seattle Mariners farm system prospects. Scouting reports were created utilizing information gleaned from industry sources as well as my personal observations. For the fourth year running we are delineating two anticipated relief roles–MIRP for multi-inning relief pitchers and SIRP for single-inning relief pitchers–in our “position” column below: MIRP is for multi-inning relief pitchers while SIRP stands for single inning relief pitchers. ETAs listed generally correspond with when players must be added to 40-man roster to avoid being eligible for Rule 5 draft eligibility — though manual adjustments can sometimes occur for either way depending upon individual cases where necessary.

Other Prospects to Note
Organized into categories by type and listed according to preference within each one, here are other prospects worth noting for consideration in each one.
Rookie Level Names to Remember Adrian Quintana, RHPDylan Wilson and Walter Ford for RH play from RHP positions for Team USA while Eduardo Ponce of CJuan Cazarez is on RH only while Danery Meyer stands as RH only pitcher
Quintana, 21, possesses a well-built frame and sits 90-92 with an effective curveball. Recently promoted back to Modesto shortly before list publication, Quintana made headlines as being among the pitchers with potential. Wilson, an 18-year-old righty from Curacao, sits 88-90 with two decent breaking balls (a low 80s slider and slower vertical curveball). He’s an above average athlete but lacks physical projection. Ford, only 19, signed for $1.2 million as the 74th overall pick in 2022 but has yet to leave the complex or complete his pre-draft velocity test (89-92 in my pro looks from prior years). Ponce, an 5-foot-9 Mexican DSL catcher known for her advanced defense and bat-to-ball skills, lacks physical projection. Meanwhile Cazarez, an athletic 5-foot-11 DSL righty who’s reached up to 95 MPH, boasts an effective 12-to-6 curveball and has had fastball rides exceeding 40 miles an hour; Meyer stands 6-foot-4 at 17 years old but sports 40 athlete status while still boasting fastball rides that ride well and depth on his low 70s curveball.
Funky Low Slots and Players Who Know How to Spin ItTy Cummings, RHPLOGAN GRAGG,RHPTYLER CLEVELAND, RHPBlas Castano RHPTyler Cleveland,RHP Will Schomberg AND Anyelo Ovando
Cummings was selected in the seventh round from Campbell last year and features a low-90s fastball with an effective slider – ideal characteristics of an ideal no. 6-9 starting pitcher. Meanwhile, Cardinals released Gragg after posting an average double-A ERA of 5.74 during 2018. The Mariners signed Cleveland as a junkballing righty with five pitches who has found success out of their bullpen this season, having previously pitched at Central Arkansa as an individual starter. Unfortunately, due to his lower slot rightiness he has experienced walk issues as soon as being moved over from starting to bullpen this season. Castano, 25, is an undrafted free agent out of Davidson with outstanding breaking ball spin, who had success throwing cutters and curveballs to Low-A hitters before receiving his recent promotion to A ball. Schomberg was another undrafted free agent with seven feet of extension who may serve as an emergency starter at some point during his career. Finally, Ovando (23, A ball reliever with messy delivery but plus curveball and plus seven foot extension).
Contact Bats and Extra OutfieldersBrock Rodden, 2Bade Marlowe and RJ Schreck are three outfielders with experience who may prove useful as contact bats and extra outfielders respectively.
Brock Rodden, who excels as both an offensive and defensive switch-hitter, spent two seasons at an Oklahoma JUCO before enrolling at Wichita State. There he recorded more walks than strikeouts while hitting 17 bombs each season with 17 walks taken per season for WSU. Marlowe appeared capable of extra outfield duty for some time at Tacoma but has recently seen his strikeout rates soar and has made 34 major league debuts so far since coming over from Vanderbilt (Screck); this left fielder from Vanderbilt has found great bat-to-ball success at Everett thanks to having such short porch swinging!
Seattle’s big league roster features elite starting pitching but inconsistent offense. So it only seems logical that their farm system boasts promising young hitters as part of its arsenal. Cole Young stands out as an advanced infield prospect who could provide short-term relief at second base for Seattle. But these other prospects remain far removed from MLB and/or redundant with pieces already present on Seattle’s big league roster. Harry Ford will need time to adjust before becoming successful against major league pitchers. Cal Raleigh may get in his way at bat and slow him down considerably as they adjust. Colt Emerson and Young are similar defenders; J.P. Crawford has taken his position at shortstop through 2026 without falter. As the Astros surge past a Mariners squad that has seen its lead drop from 10 games on June 18 to two as of publication, none should remain untouchable when trading deadline approaches.
At the forefront of Seattle’s system is an impressive group of everyday hitters that could become stars one day, though none has an obvious star ceiling yet. Due to a lack of universal Top 20 type talents and below-average overall farm depth, however, this system ranks just below league median. Both international and domestic amateur scouting departments were responsible for these potential everyday guys; their impact has since become much clearer on major league rosters due to Luke Raley, Dominic Canzone and other graduates that graduated.
Lack of impact pitching in the system doesn’t loom large as its development has historically been handled well; plus, big league club is already strong when it comes to pitching depth. Scouts and analysts who uncovered good arms later in draft can help maintain depth; it may be that pitchers drafted or acquired recently who are currently injured will inject significant value when healthy again.
