Along with a Top 10 Dynasty Baseball Prospects Ranking, I wanted to highlight some interesting MLB guys for every team and talk some strategy to give a more complete Dynasty Team Report. Like during the regular season, I’m still going to be posting a few articles a month for free on my website. This is one of those articles. Here is the Seattle Mariners 2023 Dynasty Baseball Report (Top 10 Prospects/Interesting MLB guys/Strategy Talk):

Hitters
Julio Rodriguez SEA, OF, 22.3 – Prospects can break your heart, but the season Julio just had is why we play this game. There is nothing more satisfying in all of fantasy sports than acquiring a young prospect, letting him develop in your farm system, and then watching him explode in his MLB debut. And explode is exactly what Julio did, slashing .284/.345/.509 with 28 homers, 25 steals, and a 25.9%/7.1% K%/BB% in 132 games. He has elite speed (29.8 ft/sec sprint speed) and elite exit velocity numbers (92/96.2 MPH AVG/FB EV). He closed out the season with a bang, putting up a 1.202 OPS in his final 19 games, which could be foreshadowing for what he has in store for 2023. The only quibble is that he ran far less in the 2nd half with only 4 steals in 7 attempts in his final 50 games, but considering how fast he is, I wouldn’t get too hung up on that. 2023 Projection: 96/32/98/.278/.353/.522/26
Jarred Kelenic SEA, OF, 23.9 – Prospects can fill your heart, but the career Kelenic is having is why we curse this game. There is nothing more painful in all of fantasy sports than acquiring a young prospect, letting him develop in your farm system, and then watching him implode in the majors. And implode is exactly what Jarred did, slashing .168/.251/.338 with 21 homers, 11 steals, and a 30.0%/9.3% K%/BB% in his 147 game career. He actually managed to get worse in year 2 with a .534 OPS, 33.7% K%, and 55 wRC+ in 54 games. I wrote in the Torkelson blurb for the Tigers Team Report that I’m almost more encouraged that Tork struggled at Triple-A too considering he ripped up Triple-A in 2021. It means it just might have been a down year, which happens to almost everyone in baseball. If he went right back to destroying Triple-A, I might think he has some kind of fatal flaw vs. MLB pitchers. Enter Jarred Kelenic, who continually gets sent back down to Triple-A and goes right back to raking. He was starting to show the weakest of pulses in September with 3 homes and a 1.107 OPS in the first 7 games of the month, but it was false hope as he closed out the season going 1 for 23. Even his upside isn’t what it used to be as he now has below average speed. He’s still only 23 years old, and he has nowhere to go but up (although I said that last year too), but his name value will still probably push his acquisition cost up higher than I would be willing to go. I’m staying away. 2023 Projection: 53/17/61/.228/.299/.405/9
Cal Raleigh SEA, C, 26.4 – Raleigh became one of the premier power hitting catchers in the majors, smashing 27 homers which was tied for first with Daulton Varsho. They weren’t cheapies either as he crushed the ball with a 90.9/94.8 MPH AVG/FB EV and 22.5 degree launch. His 114 MPH Max EV was in the top 6% of the league. The high launch angle combined with a high strikeout rate (29.4% K%) is going to tank his batting average (.211 BA), so he’s basically Mike Zunino 2.0, although his strikeout problems aren’t nearly as bad as Zunino’s. 2023 Projection: 57/25/71/.225/.304/.462/2
Starting Pitchers
George Kirby SEA, RHP, 25.2 – Kirby dominated in his MLB debut with elite control (4.1% BB%) of a legitimate 6 pitch mix (4-seam, curve, cutter, sinker, slider, change). He threw each pitch at least 8% of the time, but the fastball is the money maker, throwing it 45.4% of the time and putting up a negative 18 run value on it (9th best in baseball). It led to a pitching line of 3.39/1.21/133/22 in 130 IP. As advertised from his prospect days, none of his secondaries are true out pitches, and his 24.5% K% isn’t standout with a below average 21.2% whiff%, but that is one hell of a rookie season. I’m only expecting improvements from here. 2023 Projection: 12/3.45/1.11/178 in 170 IP
Logan Gilbert SEA, RHP, 25.4 – Gilbert’s profile is very similar to Kirby’s, except slightly worse. He also has excellent control (6.4% BB%) of a heavily used 96.1 MPH fastball (53.9% usage). He put up a negative 12 run value on the pitch which was 25th overall. It led to a pitching line of 3.20/1.18/174/49 in 185.2 IP. None of his secondaries are truly standout, and while his changeup performed the best, he only went to it 8% of the time. The biggest red flag is that his stuff is mighty hittable with a 91 MPH EV against (bottom 3% of the league) and 118 MPH Max EV against (bottom 1%). His 4.11 xERA was much worst than his 3.20 ERA. K/BB numbers are still king at the end of the day, and his control will ensure a good WHIP even if the ERA rises. I would also bet on improvements to his secondaries as he already tinkered with his slider this year, throwing it 3.5 MPH faster. 2023 Projection: 13/3.58/1.16/187 in 190 IP
Bullpen
Andres Munoz SEA, Setup, 24.2 – Munoz is the top setup man to own in dynasty, and Seattle has been malleable with their bullpen in the past, so he could easily lock down a share of the closer job with Paul Sewald. He throws a 100.2 MPH fastball with a silly elite slider that put up a 50.8% whiff% and .162 xwOBA. It led to a 38.7% K% and 41.8% whiff%. If that wasn’t enough, he also has near elite control with a 6% BB% and he induced weak contact at near elite rates with a 86.2 MPH EV against. He had a 2.49 ERA with a 96/15 K/BB in 65 IP, and his 1.84 xERA was even better. The guy literally doesn’t have a weakness and has a real argument to be crowned the best reliever in baseball. 2023 Projection: 5/2.39/0.93/91/12 saves in 62 IP
Top 10 Seattle Mariners Fantasy Baseball Prospects
1) Harry Ford SEA, C, 20.1 – Harry Ford and Logan O’Hoppe were my top 2 prospect catcher targets for 2022, and both were big hits. Granted, you could have thrown a rock and hit a catcher prospect breakout with Endy Rodriguez, Bo Naylor, Edgar Quero, Diego Cartaya, Ford, O’Hoppe etc … all having big seasons. Ford used his lightning quick bat, plus speed, and mature plate approach to put up a 132 wRC+ in 104 games at Single-A. He slashed .274/.425/.439 with 11 homers, 23 steals, and a 23%/17.6% K%/BB%. The power didn’t pop, but his home ballpark is one of the worst for homers, and I have no doubts about his long term power as he doesn’t have any groundball issues. He hit 8 homers in 53 games on the road and 3 in 51 games at home. He’s a plus athlete who could play other position, so he could be the type to retain catcher eligibility while still playing 150+ games. He’s still a major buy for me in 2023. ETA: 2025 Prime Projection: 84/23/78/.268/.350/.463/16
2) Gabriel Gonzalez SEA, OF, 19.3 – Gonzalez might not have the highest upside as he’s not a huge tools guy. He doesn’t have monster power or speed, and he’s not a hulking human being at about 5’11”, but what he does have is monster baseball skills. He destroyed the DSL in 2021 with a 141 wRC+ in 54 games, then he crushed stateside rookie ball in 2022 with a 164 wRC+ in 35 games, before making his full season debut and barely slowing down with a 14%/8.7% K%/BB% and 116 wRC+ in 32 games at Single-A. He has a plus hit tool with near elite contact rates his entire career, and there is plus power potential especially considering the quality of contact. He’s not a burner but he should be able to nab a handful of steals as well. He’s one of the safest teenage prospects in the game and it’s not like there isn’t some upside in here either. ETA: 2026 Prime Projection: 85/25/85/.278/.343/.473/9
3) Jonatan Clase SEA, OF, 20.10 – Clase had a big time breakout season, but nobody seemed to notice. He slashed .267/.374/.463 with 13 homers, 55 steals, and a 26.7%/13% K%/BB% in 107 games at Single-A. He has elite speed and there is some real juice in his bat with him crushing some absolute bombs. He’s only 5’8”, 150 pounds, so he’s not going to be a huge power hitter, but there should be enough to let his speed shine. The high K% adds risk which prevents his value from really exploding, but he mitigates that with high a walk rate. Clase is the type I hope falls right into my lap late in off-season prospect drafts. ETA: 2025 Prime Projection: 79/14/60/.246/.328/.398/31
4) Cole Young SEA, SS, 19.8 – Selected 21st overall in the 2022 MLB Draft, Young is kinda similar to Edwin Arroyo (selected 48th by Seattle in 2021) in the sense he doesn’t necessarily jump off the screen, but there is still an exciting set of tools led by the plus hit. He did damage in his pro debut, slashing .367/.423/.517 with 2 homers, 4 steals, and a 8/8 K/BB in 17 games split between rookie ball and Single-A (he actually performed better at Single-A than rookie). He’s a very solid 6’0”, 180 pounds with above average speed and the ability to put a sting into the ball, although his well over 50% GB% will limit his power. It’s not the highest upside profile, but it’s a safe one with the potential to contribute in every category ETA: 2026 Prime Projection: 87/17/62/.274/.340/.428/15
5) Lazaro Montes SEA, OF, 18.6 – I fell in love with Montes’ graceful lefty swing from a 6’3”, 210 pound frame last off-season, and he didn’t disappoint in 2022, slashing .284/.422/.585 with 10 homers, 3 steals, and a 33.2%/15.7% K%/BB% in 55 games in the DSL. It’s legitimate 40+ homer potential, but I can’t deny the 33.2% K% against the very weak DSL pitching isn’t concerning. The high walk rate shows that some of that was because of his extreme patience, but it gives him major hit tool risk, and as a corner outfielder, his bat will have to hit close to it’s ceiling to lock in playing time. I’m still betting on the talent long term, but not as much as I would have with better K rates. ETA: 2027 Prime Projection: 76/34/84/.238/.320/.502/4
6) Felnin Celesten SEA, SS, 17.6 – Expected to sign for over $4 million, Celesten has that super smooth lefty swing (he also hits righty) in the mold of a Marcelo Mayer, George Valera, and Zac Veen. It just screams offensive potential. He’s also an excellent athlete with plus speed. We’ve seen plenty of international prospects with smooth swings just not hit enough against more advanced competition, but it’s hard not to fall in love with the swing and tools. Considering the last couple international classes haven’t really popped, Celesten could come at a very reasonable price in 2023 First Year Player Drafts. This could be the year to dive back into this market. ETA: 2028 Prime Projection: 83/26/87/.268/.336/.470/18
7) Bryce Miller SEA, RHP, 24.7 – Miller showed major control problems in 2021 in the SEC in his first year as a starter with a 5.9 BB/9 in 56.2 IP, but Seattle took a shot on his big stuff in the 4th round, and it paid off in 2022. He put up a pitching line of 3.16/1.04/163/46 in 133.2 IP at mostly High-A and Double-A. He pitched just as well at each level. He throws gas with a mid 90’s fastball and has 3 quality secondaries in his slider, change, and curve. He certainly still has some reliever risk, but there is real fantasy upside here, especially considering this was only his 2nd year as a starter. 2023 Projection: 3/4.19/1.34/51 in 50 IP Prime Projection: 10/3.76/1.30/168 in 160 IP
8) Emerson Hancock SEA, RHP, 23.10 – Hancock was art of pitching his way through Double-A with a 2.19 ERA and 64/21 K/BB in his first 70 IP, but the lack strikeouts caught up with him in the end with a 7.62 ERA and 28/17 K/BB in his final 28.1 IP. His 3.75 ERA was still solid overall, but the 22.3%/9.2% K%/BB% and 5.43 xFIP doesn’t look as good. He has the pedigree as the former 6th overall pick in the draft, and he looks the part when you watch him with 3 electric pitches (mid 90’s heat, change, slider), but the numbers say back end starter. I’ll split the difference and put a #4 starter tag on him. 2023 Projection: 2/4.42/1.38/56 in 65 IP Prime Projection: 10/3.93/1.27/158 in 170 IP
9) Cade Marlowe SEA, OF, 25.9 – Marlowe is in that Joey Wiemer class of prospect. He’s an older prospect with a plus power/speed combo and major hit tool issues. He slashed .287/.377/.487 with 23 homers, 42 steals, and a 27.0%/10.7% K%/BB% in 133 games at mostly Double-A. He made it to Triple-A for 13 games and his K% spiked to 38.3%, which isn’t a great sign. He’s older than Wiemer and the power/speed combo isn’t as big as Wiemer, but these types of prospects give you legitimate upside without having to draft a teenager who is likely at least 3-4 years away. I doubt Seattle will just hand him a starting job, so he will have to scratch and claw for playing time with a very short leash when he does get his shot. He also hits righties significantly better than lefties, so a platoon role is in play. 2023 Projection: 19/5/20/.221/.290/.398/6 Prime Projection: 51/16/60/.236/.316/.431/12
10) Tyler Locklear SEA, 1B/3B, 22.4 – Selected 58th overall in the 2022 MLB Draft, Locklear put up video game numbers in the Atlantic 10, slashing .402/.542/.799 with 20 homers, 6 steals, and a 25/47 K/BB in 62 games. He smashed in pro ball too with 7 homers and a 21.8% K% in 29 games at Single-A. The power is very real at 6’3”, 210 pounds and he also has a good feel to hit with a relatively short righty swing. The swing isn’t particularly athletic, he has below average speed and he’s likely a 1B long term, so the bat will have to hit it’s absolute ceiling to hold down a full time job. ETA: 2025 Prime Projection: 64/22/77/.254/.321/.466/2
11) Axel Sanchez SEA, SS, 20.4 – Sanchez looks cool as a cucumber in the box before exploding on the ball. He has easy athleticism and was known more for his glove than his bat prior to this year. The bat really shined in 2022 though, slashing .283/.365/.510 with 10 homers, 13 steals, and a 24.9%/9.1% K%/BB% split between rookie (117 wRC+ in 27 games), Single-A (155 wRC+ in 33 games), and High-A (38 wRC+ in 8 games). There is still plenty of refinement needed, but he reminds me a bit of Jeremy Pena. ETA: 2026 Prime Projection: 76/20/72/.250/.322/.428/13
12) Michael Arroyo SEA, SS/3B, 18.5 – Arroyo was a high priced international signing who was known for his plus hit tool and mature approach. He came exactly as advertised in his pro debut, slashing .314/.457/.484 with 4 homers, 4 steals, and a 16.6%/13.6% K%/BB% in 49 DSL games. He’s similar to Gabriel Gonzalez in that he isn’t a huge tools guy at 5’10”, 160 pounds, although his power potential probably doesn’t rise quite to Gonzalez’ level. I want to love Arroyo even more, but it’s hard for me to fly a guy up my rankings who doesn’t have huge upside, is a long way off from the majors, and hasn’t even debuted stateside. ETA: 2027 Prime Projection: 83/21/73/.273/.339/.447/6
13) Taylor Dollard SEA, RHP, 24.1 – Dollard isn’t a big velocity guy with a low 90’s fastball, but he mitigates that by going to his plus slider very often (he also throws a curve and change) and by hitting his spots with at least plus control (5.4% BB%). He put up a pitching line of 2.25/0.95/131/31 in 144 IP at Double-A. He’s not a big strikeout guy, and his .248 BABIP with a 4.66 xFIP shows he needed some luck to put up those numbers. Despite his age, he’s still relatively projectable at 6’3”, 195 pounds, so if he’s able to add velocity in his mid 20’s, he could easily beat his current back to mid rotation projection: 2023 Projection: 1/4.46/1.31/23 in 30 IP Prime Projection: 9/4.12/1.26/152 in 165 IP
14) Bryan Woo SEA, RHP, 23.2 – Woo returned from Tommy John surgery in June and immediately showed the big stuff is back with a mid 90’s fastball, plus slider, and a changeup that flashes plus. He was a strikeout machine in the lower minors with a 85/22 K/BB (4.11 ERA) in 57 IP spread across 3 levels (rookie, A, A+). He’s now destroying the AFL with a 0.84 ERA and 16/4 K/BB in 10.2 IP. I generally discount AFL performance, but one of the exceptions is from a pitcher who was out for most of the season. You can’t fake big time stuff, and Woo certainly has big time stuff. This off-season is definitely the time to get in on Woo before his value explodes in 2023. ETA: 2024 Prime Projection: 9/3.94/1.32/161 in 155 IP
Dynasty Baseball Thought/Strategy of the Day (which may or may not be related to the team I’m covering that day)
As I alluded to in the Jonatan Clase blurb, not every target of mine is someone I’m necessarily going to really stick my neck out to grab. If you’re constantly reaching for all of your favorite underrated targets, you’re basically eliminating the excess value they should provide to you. The value comes from letting that player fall right into your lap. Gaming the draft is a big part of fantasy success, and you have to risk losing a guy. If you miss out on them, c’est la vie. I certainly have some targets I need to have and am willing to go above and beyond to get, but you have to pick your spots.
