The Mariners’ starting pitchers can be broken into two different groups. There are the veterans at the top in Marco Gonzales and James Paxton, who between them have spent about 10 seasons in Seattle. They’ve both been successful, and so long as they stay healthy — not a given for Paxton — we know what to expect from them. The other half of the Mariners’ rotation is the young guys: Justus Sheffield, Justin Dunn, Logan Gilbert, and others. Each of them had or has considerable prospect stock, but while they’re expected to be successful at some point in the future, we can’t be sure that success will arrive in 2021.

Holding those two groups together in the middle is left-hander Yusei Kikuchi, fittingly, as he represents something from both. At 29 years old and with nine seasons spent in NPB, he’s already a veteran. But as with the young guys, there is still a lot to learn about how he will fare in the majors, given that his MLB experience amounts to two years. The first was 2019, his rookie season and first time pitching in the U.S., when he posted a 5.46 ERA and 5.71 FIP in 161.2 innings as Seattle finished last in the AL West.

The pandemic-shortened 2020 season, though, suggested there could be a lot more to him. Kikuchi’s ERA stayed above 5.00, but his FIP plummeted to 3.30, and he made significant progress with his strikeout and home run rates. If his surface numbers take the step forward this year that his peripherals did last year, it would be a major boost to the Mariners as they try to crawl toward contention.

Jarred Kelenic is right, or at the very least, he’s not wrong. There’s no reason not to take the recent claims of the Mariners outfielder and his representative, Brody Scoffield, at face value. Their story — that Kelenic was offered a pre-debut extension and that when he declined to sign it, the club refused to call him up in 2020 for service time reasons — is totally believable, and is backed up by Kevin Mather’s now infamous remarks over Zoom to the Bellevue Breakfast Rotary Club; Mather, the club’s President and CEO at the time of his remarks, resigned last week. The proposed extension, which Mather described as a “long-term deal, six-year deal for substantial money with options to go farther,” speaks both to Kelenic’s immense talent as well as the Mariners’ desire to lock him up on team-friendly terms.

Jerry Dipoto, who addressed the situation last Tuesday, is right, or at the very least, he might not be wrong. Dipoto said what one normally would about a highly-ranked prospect who is generating hype but isn’t on the roster yet. (Here it worth remembering that GMs operate within the budget strictures ownership set for them. That’s not to say Dipoto has no agency, and owners look for GMs who are willing to let this type of fiscal responsibility take precedence over winning baseball games. But in reality, ownership should be on the hook to a far greater degree than the front office in the eyes of fans.) Kelenic has only played 21 games above A-ball. He hit a very solid .253/.315/.542 in those 21 games, as a teenager mind you, and was actually remarkably unlucky, as evidenced by his exceptionally light .246 BABIP. Still, a little more seasoning in Triple-A, as Dipoto suggests, might be beneficial. Kelenic’s approach could use some tightening and his strength gains have come with some of his twitch going backwards, which is starting to hinder him defensively.

But those are nitpicks, not deficiencies that should have kept him out of Seattle. Evan White proves the case. White isn’t nearly as talented as Kelenic, but he signed a pre-debut deal and was instantly the Opening Day first baseman in 2020. His bat wasn’t ready, as evidenced by a miserable 66 wRC+ to go with an ugly 41.6% strikeout rate, yet he was there. Was White the Mariners’ best option? Maybe. But did the fact that he signed the sort of big league deal that Kelenic turned down drive the decision to have him with the major league team while Kelenic futzed around at the team’s alternate site in Tacoma? No question. Read the rest of this entry »

There were so many concerning and reprehensible elements to Kevin Mather’s address to the Bellevue Breakfast Rotary Club — given earlier this month, but unearthed, in YouTube form, by commenters on Lookout Landing yesterday — that it would be beyond the scope of a single post to adequately address them all. Mather, still the President and CEO of the Mariners at this writing and even after the Seattle Times reported his history of alleged workplace harassment in 2018, managed in the course of 45 minutes to offend on a multitude of different levels, none of which were mentioned specifically in his apology statement. Here, though, I will specifically address the element of his speech that I have the most knowledge and experience with — the one that, as a result, was the most infuriating to me. In the course of his question period, Mather, twice and entirely unprompted, denigrated his players’ ability to speak English.

The video has since been deleted from the Bellevue Breakfast Rotary Club’s channel, where it was originally updated, but it has been uploaded elsewhere; Lookout Landing also posted a full transcript here. The quotes below are pulled from the Lookout Landing transcript. First, Mather was asked by one of the members of the Club to “tell [them] about Julio Rodríguez.” Mather’s answer began like this:

Julio Rodríguez has got a personality bigger than all of you combined. He is loud, his English is not tremendous.

Later, another member asked about what support the Mariners offered to players who don’t speak English as their first language. Mather described the improvement in such supports over the last 20 years, before deciding to illustrate his point with this example:

As far as Korea, Japan, Taiwan, those players are typically older. They don’t come over as 16- or 18-year-olds, they come over as 28, 30, 32 year olds. We typically…it frustrates me…For instance, we just re-hired Iwakuma, he was a pitcher with us for a number of years. Wonderful human being, his English was terrible. He wanted to get back into the game, he came to us, we quite frankly want him as our Asian scout, interpreter, what’s going on with the Japanese league. He’s coming to spring training. And I’m going to say, I’m tired of paying his interpreter. When he was a player, we’d pay Iwakuma X, but we’d also have to pay $75,000 a year to have an interpreter with him. His English suddenly got better, his English got better when we told him that! For the older players from the Far East, we have an interpreter that travels with them. For the younger Dominicans, Venezuelans, Caribbean players, we really invest in them at a young age before they get here. Good question! It’s important.

A few days after signing Ken Giles to bolster their bullpen of tomorrow, the Mariners signed a free agent who should help the team this year, and it’s a big one for Seattle fans. On Saturday, the M’s agreed to a one-year, $8.5 million deal with James Paxton, with incentives that could bring the total outlay to $10 million. With spring training just a few days away, it’s a reunion that makes a lot of sense for both parties.

Paxton was originally drafted by the Mariners in 2010 and worked his way through the organization to make his major league debut in 2013. A litany of injuries prevented him from making an impact during the first three years of his major league career, but he broke out in 2016 when he suddenly started throwing 97 mph. He was traded to the Yankees prior to the 2019 season and was a solid presence in their rotation that year, but the injury bug struck again in 2020, limiting him to just five starts. Now, he returns to the Mariners and will share the rotation with the headlining prospect — Justus Sheffield — that came to Seattle from New York in that trade two years ago.

Paxton’s ability to stay on the mound has always been a lingering concern. The last time he made it through an entire season without at least one trip to the injured list was 2013, when he made a full slate of starts for the Triple-A Tacoma Rainiers and then made his major league debut in September. Last year, it was a strained flexor in his left forearm that sidelined him (that after offseason back surgery). The year before that it was a knee injury. He’s also dealt with arm contusions, back inflammation, and muscle strains in his fingers, arm, and torso. If you were to map out the parts of his body that have been hurt, the entire left side of his body would glow red.

Addressing a historically bad bullpen was the primary goal of the Mariners this offseason. Going back to 1969 — the year MLB lowered the mound — the 2020 Mariners bullpen posted the second worst league-adjusted FIP and the fourth worst league-adjusted ERA in a single season. They’ve already made a number of moves to strengthen their relief corps, including trading for Rafael Montero and bringing in a ton of relievers on minor-league deals. Yesterday, they capped off their offseason plan by signing a big-name closer to a multi-year deal. They locked up Ken Giles to a two-year deal, though the specific financials have yet to be reported at time of publication. The only problem is that Giles recently underwent Tommy John surgery and likely won’t pitch until 2022. Elbow troubles have plagued Giles over the last two years. He pitched through inflammation in 2019 but all that wear and tear on his arm caught up to him a season later. He threw just 3.2 innings in 2020 and went under the knife on October 1.

He’s the latest player to sign a deal like this. Garrett Richards and Michael Pineda are the two biggest names who have signed multi-year deals soon after undergoing major arm surgery. It’s an interesting move for the Mariners who have had a rather quiet offseason. They’re not quite ready to break out of their rebuild and have avoided opening the purse strings to make a splash this year. By locking up Giles now, they have him committed to their 2022 roster when they’re hoping to be more ready to compete. Read the rest of this entry »

Taijuan Walker came back strong in 2020. Coming off two seasons lost to Tommy John surgery, the 28-year-old right-hander put up a 2.70 ERA over 51-and-a-third innings. Six of his 11 starts came with the Toronto Blue Jays, who acquired Walker from the Seattle Mariners at the tail end of August in exchange for Alberto Rodriguez.

A return to health wasn’t the only thing that buoyed Walker’s rebound. Like many modern-day hurlers, the 43rd-overall pick in the 2010 draft has become an adherent of analytics and data-driven pitch-design. Currently a free agent, Walker is looking to move forward with a team that embraces those very things.

———

David Laurila: What is your background with analytics and pitch design?

Taijuan Walker: “I went to Driveline about a week after the 2019 season ended. I spent a few days there and got assessed — all of the numbers, threw a bullpen — and it was nice to see where I was at with my fastball spin rate, and more. We talked about the numbers, and how to use those numbers to know what I’m looking for.

“That was part of the reason I signed with the Mariners [in February]; they had a lot of that same technology. Woody [Pete Woodworth], the pitching coach there, is smart, and really good.”

Laurila: I assume you’d been exposed to analytics previously?

Walker: “Yes, but I had a chance to really learn the numbers, whereas before it was more like, ‘Hey, these are your numbers,’ but never really having them explained to me. It was never, ‘This is what they mean, and this is how to make [a pitch] better.’”

Laurila: How are you going about making information actionable? Read the rest of this entry »

Last week, the Mariners Player Development twitter account posted a graphic of Julio Rodriguez.

Hang it in the Louvre. ? pic.twitter.com/uIhzPuWppz

— Mariners Player Development (@MsPlayerDev) January 8, 2021

Adorned in a full uniform and sunglasses, Rodriguez’s bat is cocked just beyond his head as he begins his stride toward the mound; the #SeaUsRise hashtag in the lower left corner suggests a metaphor is at work. “Hang it in the Louvre,” the Mariners tweeted approvingly.

Compliments to artist Trevor Milless aside, this tweet stuck with me, mostly because it’s kind of odd. There aren’t many teams that retweet artwork posted on the club’s player development account, in part because most franchises don’t even have a player development account.

This is part of a pattern in Seattle. The Mariners have been rebuilding for a couple seasons and they’re not shy about promoting their good work. The major league broadcasts feature regular updates on the farm system, and the club’s TV network has aired a few minor league games. Jerry Dipoto even joined one of the broadcasts. All teams are proud of their minor leaguers, of course, but as far as I know, the Mariners are the only team to give one of them a YouTube show.

In a vacuum, there’s nothing wrong with this. Vibin’ With JRod isn’t for me, but hey, he’s a good prospect and I’m no marketer. Read the rest of this entry »

One of the “Best of 2020” articles that ran here at FanGraphs over the holidays featured an under-the-radar right-hander with a unique backstory and a knee-buckling bender. Titled Rangers Prospect Cole Uvila is a Driveline-Developed Spin Monster, the story chronicled, among things, a curveball that had spun upwards of 3,300 RPM in Arizona Fall League action. Honed with the help of technology, the pitch profiled as his ticket to Texas.

He’s no longer throwing it. Instead, Uvila is endeavoring to channel former Cleveland Indians closer Cody Allen.

“In my head, I was going to throw it until my career was over,” Uvila said of his old curveball. “Then the pandemic happened. There was a lot of time to look in the mirror, and you just don’t see big-league relievers throwing 76-mph curveballs. It’s not really a thing.”

Uvila started talking with people in the Rangers organization, as well as to the instructors he’s worked with at Driveline over the years. Their messages were essentially the same: With breaking balls — much like fastballs — velocity is king.

“Driveline R&D has this metric called Stuff Plus, which essentially takes every breaking ball over the last five years and gives it a number,” Uvila told me earlier this week. “It’s kind of like wRC+, where 100 is average. I think the highest one was a dude with the Cubs, named [Dillon] Maples, and his graded out at something like 240. So there’s this range of pitches, and looking at the list, I saw this theme of curveballs at 84-85 [mph]. I said, ‘Man, I need to throw this pitch harder.’” Read the rest of this entry »

After having typically appeared in the hallowed pages of Baseball Think Factory, Dan Szymborski’s ZiPS projections have now been released at FanGraphs for nine years. The exercise continues this offseason. Below are the projections for the Seattle Mariners.

Batters

Let’s go straight to the projection that will likely get the most grumbling: ZiPS does not think that Kyle Lewis is a budding star. It does like him better than Steamer does — it mostly comes down to ZiPS being more willing to believe he’s a .340 BABIP hitter — but not to the level where he projects as a good starter. He had a legitimately excellent rookie season, but it’ll take more than an abridged 2020 to convince ZiPS that the previous translations, generally in the .230/.270/.370 range, no longer have predictive value. That’s not to say Seattle should be actively seeking to replace or upgrade from Lewis. One of the “benefits” of being a rebuilding team is that you can give players chances to improve or show an improvement is for real, after all. But these projections see the 2020 AL Rookie of the Year race a little like 1992, with the runner-up, Luis Robert, playing Kenny Lofton and Lewis as Pat Listach. Bumping a projection up by 70 points of OPS from the results of a 60-game season remains an accomplishment.
