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.’”

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.

Taijuan Walker is coming off a strong 2020 season that followed a pair of lost seasons. The 28-year-old free agent fashioned a 2.70 ERA in 11 starts — five with the Seattle Mariners and six with the Toronto Blue Jays — after tossing just 14 innings in 2018-2019. We’ll hear from Walker on his return from Tommy John surgery and shoulder woes, as well as his pitch-design efforts, in the near future. Today we’ll touch on some of his career highlights. Earlier this week I asked the 2010 first-rounder for a ranking of his top performances to date.

“Numbers-wise it wasn’t my best, but I pitched a must-win game in Toronto,” recalled Walker, who was with the Mariners at the time. “This was [September 24, 2014] and while we didn’t end up winning, I feel like my fastball was the best it’s ever been. My breaking ball and my changeup probably were as well. We ended up losing 1-0, but stuff-wise I felt it was my best game.”

Out-dueled by Mark Buehrle in a contest that flew by in a crisp 1:59, Walker went eight innings and allowed four hits, one walk, and the game’s lone run. Six Blue Jays went down by way of the K.

Walker went on to cite his “two best games numbers-wise,” each of which was an 11-strikeout effort in a Mariners win. On July 31, 2015, he allowed just one hit — a solo home run by Minnesota’s Miguel Sanó — and a single free pass. On September 13, 2016, he threw a three-hit, no-walk, shutout against the Angels.

The offseason remains slow, but the reliever market saw some moves this week, with a trio of free agents scoring new contracts. Greg Holland signed a one-year, $2.75 million deal to come back to the Royals, who continue to act aggressively this winter. Former Brewers lefty Alex Claudio signed a one-year, $1.25 million commitment to join the Angels, who recently traded for closer Raisel Iglesias. And speaking of the Angels, Keynan Middleton signed a one-year contract with the Mariners, who also added Rafael Montero via a trade with Texas this week.

After going all in on their rebuild in 2019, the Mariners have cycled through what seems like a million different pitchers in just two years. (The real figure is 61, the highest number of pitchers used by any team over the last two seasons.) That shouldn’t be surprising considering general manager Jerry Dipoto’s reputation for roster churn and the team’s goal of building a contender in just a few years time; scouring the waiver wire and the Mariners’ minor league system for pitchers who might show enough promise to stick around for a while requires a constant flow of transactions.

Finding plenty of lumps of coal in their quest to uncover those hidden gems, Seattle’s bullpen has been particularly bad as the team prepares to contend again. Over the last three decades, no relief corps has posted a league- and park-adjusted FIP worse than the 2020 Mariners, 33% below league average. They would have had the worst league- and park-adjusted ERA too if it weren’t for the 2020 Phillies’ atrocious bullpen and their 7.06 ERA. When we adjust their collective strikeout-to-walk ratio for their historical context, the 2020 Mariners had the fourth worst K/BB+ in that period, 37% worse than league average.

With their eyes set on coming out of their rebuild as early as next year — but more realistically in 2022 — Dipoto has made addressing that historically bad bullpen a primary goal of this offseason. The Mariners already re-signed Kendall Graveman, one of the few bright spots in the bullpen this year, and selected Will Vest in the Rule-5 draft last week. Yesterday, they took another next step in bolstering their bullpen by acquiring Rafael Montero from the Rangers. In return, 17-year-old prospect Jose Corniell and a Player To Be Named Later are headed to Texas. Read the rest of this entry »
