Look, we’re in the throes of the dead part of the year. It might not be quite so dead if the Supersonics were still around, or if the Kraken were worth a damn, but here we are: grasping at straws, writing about the upcoming baseball season during a lockout with no end in sight. Worst of all: this post is almost certainly going to be out of date and moot as soon as a new CBA is signed and the Mariners can start shuffling their roster around. Weeee!
At the moment, the Mariners have 21 pitchers on their 40-man roster. As is common knowledge, even though the hypothetical regular season is just over a month away, the Mariners’ roster is anything but finalized. I would not expect the following 21 pitchers to all be on this 40-man roster on March 31st; moves will be made, and some of the people I talk about will cease to matter. At least, when it comes to Mariners fans like me.
I split up the 21 pitchers into three categories: Yes, No, and Maybe? It just so happened that each category had an equal seven members, so let’s go through them, starting with the least trustworthy pitcher and work our way up to number 1.
I suppose I should set some groundrules and define what I mean by “trustworthy”, but why don’t we get to that as the post goes along. There’s already been too much preamble, as far as I’m concerned (but I’ll be damned if I’m going to censor myself!).
No: The Least-Trustworthy Mariners Pitchers Of 2022
#21 – Juan Then
Then is an interesting starting pitching prospect who needed to be added to the 40-man roster, lest we risk losing him to the Rule 5 draft that happened some time ago. He’s yet to pitch above A-ball. Prior to the pandemic, he looked like he might be a quick riser through the minor leagues, but his 2021 wasn’t great. There’s absolutely no way he’ll pitch for the Major League ballclub this year, and odds are he’ll never play a game in Seattle as a member of the Mariners. My guess is he is trade fodder for a team looking to shed salary and build up their farm system.
#20 – Aaron Fletcher
He’s a lefty reliever who’s had a couple brief cups of coffee with the M’s in 2020 and 2021 and has a pro ERA over 12. He SUUUUUCKS. He’s young enough to turn things around, and the M’s don’t have a ton of lefty bullpen options at their disposal, but nothing I’ve seen as of yet leads me to believe he’s ready for the rigors of the Majors.
#19 – Justus Sheffield
He was once projected as a possible #1 or #2 starter, now there’s talk of him being shifted to a permanent bullpen role. He had a decently-effective 10-start 2020 season (with zero pressure), but his 2021 was a disaster. He started 15 games, struggled pretty much throughout, went on the Injured List (even though it was dubious that he was actually injured in any meaningful way), returned as a bullpen arm, and continued to struggle. I think he’s toast. He’s got no life on his fastball, and he can’t get by on nothing but sliders, because by and large his slider is only effective when it’s out of the zone, and if you see it coming, as a batter it’s easy to lay off of it.
#18 – Matt Brash
He’s another guy with no Major League experience, yet the unknown factor puts him above both Sheffield and Fletcher. He skyrocketed through the minors – spending much of 2021 in AA – before getting called up to Seattle late last year. He never did get into a game, but there was rampant speculation he was set to start one of our final games. He’ll almost certainly get called up to Seattle at some point this year, but it’s always best to temper expectations with someone so inexperienced. Nevertheless, I would expect some ups to come with the requisite downs, which already puts him ahead of the curve compared to the three guys behind him.
#17 – Wyatt Mills
He had a pretty brief cup of coffee in Seattle last year, but his numbers in Tacoma were pretty great. I would expect him to take a step forward in 2022. I don’t remember a lot about him, but for the Rainiers he had 51 strikeouts in 28.2 innings, so I’m assuming his fastball is pretty elite. Get it under control and you’ve got something.
#16 – Joey Gerber
There’s a pretty significant caveat here: I kinda/sorta trust him IF he’s healthy. But, he missed all of 2021 with injury, so that’s why you find him in the bottom third in terms of trustworthiness. Nevertheless, in 2020 he was one of our better relievers, so we know the stuff is there. Can he get it all back? That remains to be seen. I expect him to start his 2022 in Tacoma (assuming he’s off the IL and throwing again), eventually working his way back up to Seattle as need arises.
#15 – Justin Dunn
I kinda think I have more confidence in Dunn than I should. He often gets lumped in with Sheffield, as both are working their way through the organization at a similar pace. Dunn also had a solid – if unspectacular – 2020 season. Unlike Sheffield, Dunn actually flashed some improvement in 2021. Now, granted, Dunn was still effectively wild – walking a ton of guys, while not necessarily giving up a lot of hits – but his FIP went down almost two full points, and his strikeout rate improved. He seemed to be in better physical shape in 2021, and that translated to an improved fastball. Command has always been his bugaboo, but you’d think experience would help him rein that in a little bit. Unfortunately, his 2021 was cut short due to injury; his final appearance came in mid-June. He kept trying to return, but repeatedly suffered setbacks. It doesn’t appear he had surgery on his shoulder, so we’ll see if he was able to fully recover with conservative care. We’ll also see if he gets any more chances to start, or if the team moves him to the bullpen full time. Lots of questions here.
Maybe?: The Medium-Trustworthy Mariners Pitchers Of 2022
#14 – Erik Swanson
Swanson came over in the Sheffield deal and I’ll admit, I wrote him off after his 2020 season. He was another starter, but he got demoted to the bullpen a year prior to Sheffield. As it turns out, though, that was the best thing for him. Swanson was a middle-tier reliever in a VERY good 2021 M’s bullpen, providing solid numbers throughout his 33 appearances. There are times he’ll get knocked around, but he flashed a live fastball and kept us in a lot of games a lesser reliever might’ve let get out of hand. Still, if there’s a negative regression candidate, I think Swanson is our guy; I could see his ERA balloon back up over 5 or 6 runs relatively easy. His secondary pitches aren’t super thrilling; until he builds them up, he’s going to continue being overly reliant on his fastball, which is hittable for Major League batters.
#13 – Andres Munoz
He got in one game at the very end of 2021, pitching 0.2 scoreless innings. The good news is: he recovered from his injury. The bad news is: he’s had almost two full years off. His fastball is electric, but he’s probably a guy we don’t want to push too hard in the early going. He’ll have every opportunity to win a bullpen job in Spring Training though, and the sky is the limit on his potential. But, I’d like to see him do it a few weeks before I start buying in 100%.
#12 – Yohan Ramirez
Ramirez is another guy with a live fastball, but plenty of control/command issues. Nevertheless, he came up HUGE in some high-pressure spots in 2021. He also shit the bed pretty spectacularly in equal numbers, so the potential is there, the health is there, but the limitations are pretty stark. Thankfully, there are plenty of right-handed bullpen options ahead of him, so we don’t NEED him right away.
#11 – Ken Giles
We signed Giles prior to the 2021 season knowing full well he was injured and would be missing the entire year. But, we signed him specifically so he could be a significant bullpen piece in 2022; this was the plan all along. He’s a veteran with plenty of closing experience, and was one of the best relievers in baseball in 2019. Another heater guy, he should slide in quite nicely with our returning bullpen guys. We don’t need him to be a closer, but it’s nice knowing he’s there in case the others aren’t quite as good as they were last year. The risk, of course, is that Giles has had two years off, essentially. Will he last the duration? Or, is he just a walking injury waiting to happen?
#10 – Diego Castillo
I’m probably lower on Castillo than I have any right to be, but this is a guy whose ERA numbers have always outperformed his FIP numbers. He also was decidedly worse last year with the Mariners than he was with the Rays (prior to our trading for him). Not that he was terrible with the M’s, but every appearance felt like a rollercoaster (askew hat tip to Fernando Rodney). I don’t trust him! I know he’s pretty good, but for the life of me I don’t trust him. Part of trust is knowing what to expect ahead of time, and I feel like I never know if we’re going to see the Good Diego Castillo or the Bad Diego Castillo.
#9 – Anthony Misiewicz
Now, with Misiewicz, there’s a guy you can set your watch to! He’s the top lefty reliever in the bullpen, so right away not a lot is expected of him. Even with the rule changes to how relievers are used, more often than not you can get away with having him throw less than a full inning. That’s when he’s at his best. Trying to stretch him into multiple innings is when you’re looking at disaster. However, given his youth, and the volatile nature of relievers, I’ve got a gut feeling that he’s due for some positive regression. Having said that, bank on this being my worst take of this post; putting him anywhere near the Top 10 is probably foolish, but I yam who I yam.
#8 – Nick Margevicius
Here’s another guy who I have to say at the top: IF he’s healthy. I like him, though. As a long reliever, I think he’s effective. He’s a nice guy to have in the bullpen if a starter struggles or gets hurt. He’s nice lefty insurance in case our other bullpen lefties struggle. All in all, he can do a lot of things that help a ballclub. More often than not, he’ll keep you in ballgames. That’s all I ask from a guy like this. Granted, his terrible career numbers are his biggest detriment (and the reason why he isn’t in the good category), but he’s still pretty young.
Yes: The Most-Trustworthy Mariners Pitchers Of 2022
#7 – Logan Gilbert
I should say at the onset that I’m VERY high on these top 7 pitchers. So, just because Gilbert falls in at #7 doesn’t mean I’m questioning him. I’m just being a little overly cautious. He was a rookie in 2021 and I think it’s safe to say he out-performed expectations. Most importantly: he improved as the season went along, becoming one of our very best starters by season’s end. That’s tremendous for someone so young; he should be a mainstay in the rotation for many years to come. He might not be an Ace, but he’s a solid #2 or #3, right now. All that’s left is to be consistently great, throughout the year. There will still be occasional bumps in the road in 2022, but they should be fewer and further between; that’s exciting.
#6 – Marco Gonzales
Marco was on a steady upward trajectory through 2020 before regressing a bit in 2021. I will say that he was throwing better at season’s end, and it’s likely he was dealing with a lot of injury issues throughout the season, but some of his poor starts were just disconcerting enough to sour me on him a tad. A tad! I still think for what he is, he’s good for this organization. Marco will still keep the M’s in ballgames more often than not. He’s just not, you know, an Ace. Thankfully, we no longer need him to be. As a #3 or #4 starter, I think he’s just fine.
#5 – Chris Flexen
This might be a little low for someone who was unquestionably the best Mariners starter of 2021, but a lot of the projections have Flexen as a significant negative regression candidate. It did seem like he wiggled off the hook quite a bit last year, and he might not be so lucky a second time around. The flipside to that argument is: he figured out how to be a starting pitcher over in South Korea and now he’s a completely different animal. That’s what I’m hoping for – that’s why I still have him in my Top 5 – but I’m allowing for there to be more bad outings out of him in 2022. That doesn’t mean he’ll totally faceplant; I still expect him to keep us in games by and large.
#4 – Paul Sewald
Now, HERE is probably my second-most laughable ranking of this post. Sewald was hands down the best pitcher in the organization last year. But, he was almost unsustainably elite last year, and I have a hard time believing he’s going to continue being That Guy going forward. Don’t get me wrong, he was one of my favorite Mariners last year. But, you could see him start to get touched up towards the end of the season, and that strikes me as very ominous. I hope I’m wrong!
#3 – Robbie Ray
If there’s anyone destined to rip our hearts out, it’s the guy who has parlayed one elite pitching season into a big-money, long-term deal. He had one previous All Star year in 2017, but his 2021 Cy Young season is why he’s here. The pressure is on, because not only is he our Ace, but he’s joining an up-and-coming roster with increased expectations. I’m heading into this year with love in my heart, confident that his stuff will continue to lead the way. But, in the back of my mind, there are dark, sinister thoughts of the albatross he could morph into, from the very onset. The Mariners have a long and fucked history of free agent starting pitchers coming in here and stinking straight away. I hope he’s not another notch on our bedpost.
#2 – Drew Steckenrider
It’s a total mindfuck to have my top two most-trustworthy pitchers be two other righty relievers not named Paul Sewald, but I don’t know what to tell you. I like Steckenrider. I don’t think he’s a closer, though he has that experience. I thought Scott Servais used him perfectly last year, pitching him based on matchups. Sometimes he was our closer, but sometimes he came into the game in the 7th or 8th innings. He’s just a steady, hard-throwing righty who produced crazy-effective results.
#1 – Casey Sadler
Have you seen his numbers?! Sub-1 ERA. Has a fastball in the upper 90’s, yet his best pitch is his slider; I love everything about his repertoire! He’s decidedly not a closer – and there’s no reason to expect that to change – but as a guy you mix and match with, I think no one is better on this team. The best thing about the bullpen in 2021 was how there weren’t really any super egos. The guys settled into their roles, but nothing was set in stone. They went into games on an as-needed basis, and absolutely dominated. It gives me hope for 2022, even though I know in my mind the likelihood of negative regression hitting all of these guys collectively.
