Mariners, Luke Barker Agree To Minor League Deal

By Steve Adams | April 15, 2024 at 12:30pm CDT

The Mariners agreed to a minor league contract with right-handed reliever Luke Barker, Jon Morosi of MLB.com reports. The Gaeta Sports client will head to Triple-A Tacoma.

Barker, 32, made three appearances for the Brewers in 2022 — his lone MLB experience to date. The right-hander was undrafted out of Division-II Chico State University in California back in 2015 but parlayed a dominant showing in the independent Frontier League into a minor league look with the Brewers organization. He spent the next six seasons in the Brewers system, working toward that ’22 debut.

While Barker was tagged for five runs in four innings during his MLB cup of coffee, his minor league track record is outstanding. In 261 2/3 minor league innings, the righty carries a 2.38 ERA, 27.6% strikeout rate and 6.4% walk rate. That includes three seasons of Triple-A work — a total of 116 1/3 frames with a 2.32 earned run average, an even better 30.4% strikeout rate and a 6% walk rate. Barker doesn’t throw hard, averaging just 91 mph on his heater during his brief MLB look, but he’s routinely posted swinging-strike rates north of 14% in the upper minors.

Barker didn’t pitch in 2023. He spent the season rehabbing from Tommy John surgery after suffering a UCL tear late in the 2022 campaign. He’ll now join just the second organization of his career.

The Mariners aren’t short on talented relievers, though two of their best are currently on the 15-day injured list: righties Matt Brash and Gregory Santos. Brash was slowed by a bout of elbow inflammation during spring training, while Santos suffered a lat strain late in camp. Neither has pitched in the big leagues or on a minor league rehab assignment so far this season. Barker will give the M’s some more depth in the upper minors. Seattle has a recent track record of striking gold on unheralded bullpen acquisitions — Paul Sewald, Drew Steckenrider, Justin Topa, Gabe Speier, Tayler Saucedo among them — and Barker will hope to add his name to the list.

AL West Notes: Stephenson, Canzone, Verlander, Valdez

By Mark Polishuk | April 14, 2024 at 5:44pm CDT

Robert Stephenson ended his minor league rehab outing after four pitches yesterday, as the Angels right-hander called for the team trainer and then left the mound. Manager Ron Washington told reporters (including Jeff Fletcher of the Orange County Register) that Stephenson would be undergoing tests, but didn’t offer any other details about the situation.

Shoulder inflammation kept Stephenson from pitching during Spring Training, yet after beginning the season on the 15-day injured list, the reliever seemed to be making good progress in his recovery and was looking to be part of the Angels’ roster before April was over. Yesterday’s news seems to put that timeline in jeopardy, and the only hope now is that Stephenson’s setback is less ominous than it seemed. A dominant four-month stretch with the Rays last season turned Stephenson into one of the more sought-after commodities in the free agent relief market this past winter, and the Angels landed the righty on a three-year, $33MM contract.

Beau Taylor Retires, Joins Mariners’ Triple-A Coaching Staff

By Nick Deeds | April 14, 2024 at 2:30pm CDT

Former big league catcher Beau Taylor has retired, and taken a new role as the first base coach of the Mariners’ Triple-A Tacoma affiliate. An earlier version of this post indicated that Taylor had signed a minor league deal with the M’s, but as explained by Tacoma Rainiers broadcaster Mike Curto, Taylor has decided to wrap up his playing career.

Taylor was selected by the A’s in the fifth round of the 2011 draft, but did not make his big league debut with the club until 2018, when he slashed .200/.333/.400 in a seven-game cup of coffee with Oakland. Taylor spent the next two seasons bouncing between the A’s as well as both Toronto and Cleveland as a depth option behind the plate, appearing in just 18 big league games during that time. The catcher’s seven-game stint in Cleveland during the shortened 2020 season represents his most recent big league experience.

Since then, Taylor has spent time in the Reds, A’s, and Orioles organizations at the minor league level, most recently batting a decent .222/.365/.368 in 50 games split between Oakland and Baltimore’s Triple-A affiliates during the 2022 season. Taylor departed affiliated ball last year in favor of signing with the Atlantic League’s High Point Rockers and enjoyed a strong season in indy ball. Beau appeared in 77 games (catching 61) and slashed a strong .291/.386/.453 with nine homers and 16 doubles in 316 trips to the plate.

Mariners Announce Several Roster Moves

By Steve Adams | April 8, 2024 at 4:15pm CDT

4:15pm: Bolton is dealing with kidney stones, per Ryan Divish of The Seattle Times.

3:10pm: The Mariners shook up their bullpen with a series of roster moves Monday. Right-handers Brett de Geus and Tyson Miller were selected to the 40-man roster from Triple-A Tacoma, with righty Ty Adcock being designated for assignment to open a spot on the 40-man roster. Right-handers Cody Bolton and Collin Snider were both placed on the 15-day injured list — the latter due to a knee contusion and the former with what the team labeled a “general medical issue.” The Mariners also reinstated first baseman Ty France from the paternity list and optioned infielder/outfielder Samad Taylor to Tacoma.

Both Miller and de Geus have big league experience, albeit fairly minimal. The 28-year-old Miller was a fourth-round pick by the Cubs back in 2016 and has pitched for five different teams over the past four years (Cubs, Rangers, Mets, Dodgers, Brewers). In 31 career innings, he’s been tagged for an ugly 6.97 ERA, though his Triple-A work is far better. Miller was roughed up for an ERA north of 7.00 in his first taste of Triple-A as a 23-year-old back in 2019. In parts of three seasons since that time he’s logged a 3.85 ERA in just under 200 innings. That includes 43 2/3 innings of 3.50 ERA ball with the Triple-A clubs for the Dodgers and Mets last year, during which he punched out 28% of his opponents.

The 26-year-old de Geus pitched 50 MLB frames between the Mariners and D-backs back in 2021 after Texas plucked him from the Dodgers in the 2020 Rule 5 Draft. He made 19 appearances as a Rangers and another 26 as a D-back, struggling mightily in both stops. Given that de Geus pitched in A-ball in 2019 then didn’t pitch with an affiliate in 2020 due to the canceled minor league season, it’s not all that surprising that he was hammered by MLB hitters in his debut campaign. In those 50 frames, he yielded a 7.56 ERA.

Even to this point in his career, de Geus only has 14 Triple-A frames under his belt. He’s been hit hard in that tiny sample as well, but he pitched 35 1/3 innings with a 2.80 ERA in Double-A for the Royals last season. De Geus has plenty of experience working multiple innings as a reliever and has also been a starter in the past, so he can provide some length to the Seattle bullpen while he’s up.

Adcock, 27, made his big league debut with the Mariners in 2023. The former eighth-round pick tossed 15 2/3 innings with a 3.45 ERA and 19% strikeout rate out of Scott Servais’ bullpen and didn’t issue a walk or hit any of his 58 opponents with a pitch. Adcock was never going to sustain that level of command, but he still walked only five of the 75 hitters he faced between High-A and Double-A last year (6.66%). However, he’s already issued three free passes in 2024 despite facing just a dozen opponents. The Mariners will have a week to trade Adcock, attempt to pass him through outright waivers or release him.

Mariners Release Sean Poppen

By Leo Morgenstern | April 5, 2024 at 9:12pm CDT

The Mariners released right-handed pitcher Sean Poppen today, according to his player page on MLB.com (h/t to Tacoma Rainiers broadcaster Mike Curto). Poppen, 30, signed a minor league deal with the club in January.

The Twins selected Poppen out of Harvard in the 19th round of the 2016 draft. Though he was never a highly-regarded prospect, the righty rose through the ranks of Minnesota’s system, succeeding at every step along the way. He put up a 2.97 ERA in eight games of Rookie ball, a 2.77 ERA in 18 games at Low-A, a 3.15 ERA in 19 games at High-A, a 3.96 ERA in 26 games at Double-A, and a 1.55 ERA in five games at Triple-A before he was first called up to join the Twins in 2019. He bounced back and forth between the majors and Triple-A over the next four seasons, while he also bounced from the Twins to the Pirates to the Rays to the Diamondbacks. In a total of 63 MLB appearances from 2019-22, he pitched to a 5.08 ERA and 4.12 SIERA, earning three wins, one save, and six holds.

Following the 2022 season, the Padres claimed Poppen from the D-backs. Out of minor league options, he was soon designated for assignment and sent outright to Triple-A El Paso, where he spent the 2023 campaign. Over 58 1/3 innings, he posted an ugly 6.33 ERA and a poor 1.70 K/BB, his worst in any season at any level. He elected free agency in November.

Although Poppen received a spring training invite from the Mariners this year, his time with Seattle would turn out to be short. He pitched well in five outings this spring, striking out eight and walking just one in 5 2/3 innings of work. Unfortunately, he didn’t look nearly as sharp in his Triple-A debut with the Tacoma Rainiers, giving up two walks, two homers, and four earned runs over two frames in a 7-9 loss to the Oklahoma City Baseball Club. While he performed much better in his second appearance, retiring all four Salt Lake Bees batters he faced, it wasn’t enough to save his job in the Mariners organization. Poppen is now a free agent.

Mariners Release Cory Abbott

By Darragh McDonald | April 4, 2024 at 7:16pm CDT

The Mariners released right-hander Cory Abbott yesterday, according to his transactions tracker at MLB.com. He’s now a free agent and can be signed by any club.

Abbott, 28, signed a minor league deal with the club in January and was in big league camp until being reassigned to minor league camp at the beginning of March. He was with Triple-A Tacoma long enough to make one regular season start lasting three innings, during which he allowed three earned runs on four hits and two walks while recording two strikeouts.

Selected by the Cubs in the second round of the 2017 draft, he was a notable prospect coming up the minors but hasn’t been able to find success in the majors or in Triple-A. Prior to the pandemic, he posted a 2.84 earned run average in the minors, getting as high as Double-A. Since the minors were canceled in 2020, he’s pitched in parts of four Triple-A seasons with a 5.51 ERA in 189 1/3 innings. He has struck out an impressive 28.5% of batters faced in that time but has also given out walks at a 12.9% clip.

He’s also thrown 104 2/3 innings at the big league level from 2021 to 2023 but with a 6.02 ERA. His 20.2% strikeout rate and 11.4% walk rate in that time were both a few points worse than league average.

Abbott’s lack of results at both the major league and Triple-A levels will tamp down his interest, but the Triple-A strikeouts are interesting. If any club feels they have the key to unlocking something with Abbott, he can be had for another no-risk minor league deal. If he eventually winds his way back to the majors, he is out of options but has just over a year of service time and therefore has years of potential club control.

Mariners To Sign Dallas Keuchel To Minor League Deal

By Darragh McDonald | April 2, 2024 at 7:30pm CDT

The Mariners are signing left-hander Dallas Keuchel to a minor league deal, per Daniel Kramer of MLB.com. The WME Baseball client will report to Triple-A Tacoma when the deal is complete.

Keuchel, 36, was once one of the best pitchers in the league, even winning the American League Cy Young in 2015. But he has been more in journeyman mode over the past three years. He made 175 starts from 2014 to 2020 with an earned run average of 3.25 over that stretch. His 19.8% strikeout rate in that time wasn’t special, but he limited walks to a 6.7% clip and got grounders on 59.6% of balls in play. That grounder rate was the highest in all of baseball, among those with at least 450 innings pitched in that time period.

His rate stats began to trend in the wrong direction in 2021, as his ERA jumped to 5.28. In 2022, things got even worse and he was released by the White Sox, later bouncing to the Diamondbacks and and Rangers for brief stints. He finished that year with a ghastly ERA of 9.20 in 60 2/3 innings. His ground ball rate fell to 50.2%, still strong but well below his previous levels. He only struck out 14.9% of batters faced and gave out walks at a 10.2% clip.

Last year, he worked out with Driveline Baseball in an attempt to regain some lost velocity and movement on his pitches, eventually landing a minor league deal with the Twins in June. He tossed 32 innings at the Triple-A level with a 1.13 ERA, 21.2% strikeout rate, 9.1% walk rate and 61.5% ground ball rate. That ERA was a mirage as he wasn’t going to maintain a 95% strand rate but his 4.17 FIP was still an improvement over the form he showed in the previous year.

The Twins added him to the big league roster at the start of August and he tossed 37 2/3 innings down the stretch in a swing role but his work wasn’t as impressive in the bigs, as he posted a 5.97 ERA in that time. His 14.5% strikeout rate, 10.5% walk rate and 52.8% ground ball rate were all fairly close to his 2022 numbers.

The Seattle rotation recently took a hit when Bryan Woo landed on the injured list due to some elbow inflammation. They still have a strong group of five guys with Luis Castillo, George Kirby, Logan Gilbert, Bryce Miller and Emerson Hancock in the rotation, but Keuchel will give them some extra depth. He will presumably need a few weeks to get into game shape anyway after missing Spring Training and the rotation picture could easily change between now and then.

Mariners Claim Sammy Peralta From White Sox

By Darragh McDonald | April 2, 2024 at 3:00pm CDT

The White Sox announced that left-hander Sammy Peralta has been claimed off waivers by the Mariners. The southpaw was designated for assignment on Opening Day and has now been assigned to Triple-A Tacoma. The Mariners had two open spots on their 40-man roster, which is now at 39.

Peralta, 26, just made his major league debut with the Sox last year, frequently being shuttled between Triple-A and the big leagues. He ultimately tossed 20 innings in the majors with a 4.05 earned run average, striking out 20% of batters faced while walking 12.2%. He seemed to do a decent job of limiting damage, as his average exit velocity, barrel rate and hard hit rate were all better than average in that small sample.

He also tossed 69 innings over 29 appearances in Triple-A with a 5.09 ERA, though he likely deserved better. His 23.1% strikeout rate and 6.4% walk rate were both strong but a 59.2% strand rate seems to have hampered him, which is why his 4.21 FIP was almost a full run better.

The Mariners are currently a little bit snakebit in the bullpen, with Gregory Santos and Matt Brash trying to come back from injuries while Jackson Kowar is out for the year due to Tommy John surgery. They have two lefties on the big league roster in Gabe Speier and Tayler Saucedo but Peralta will give them a third option on their 40-man for when a need arises.

He still has two option years and less than a year of service time, so he can be a long-term depth piece for the club if he continues to hang onto that 40-man spot. The M’s have done a good job in recent years with unearthing hidden gems by grabbing fairly unheralded relievers and polishing them until they shine, so the club and Peralta will be hoping he is the latest point on that trendline.

Dodgers Claim Taylor Trammell

By Steve Adams | April 2, 2024 at 1:00pm CDT

The Dodgers have claimed outfielder Taylor Trammell off waivers from the Mariners, who’d designated him for assignment last week, Robert Murray of FanSided reports. Trammell is out of minor league options, so he’ll go right onto the Dodgers’ active roster.

Now 26 years old, Trammell was the No. 35 overall pick by the Reds back in 2016. He ranked among the game’s top 100 prospects each season from 2018-21 and has participated in a pair of Futures Games but hasn’t yet found success in the majors. He had multiple auditions with the Mariners — who acquired him alongside Andres Munoz and Ty France in exchange for Austin Nola, Austin Adams and Dan Altavilla — but has produced only a .168/.270/.368 batting line with a huge 37% strikeout rate in 351 MLB plate appearances.

That said, Trammell has been vastly better in Triple-A. He’s spent parts of three seasons there as well, turning in a stout .274/.381/.506 batting line with a 24% strikeout rate that’s worlds better than his MLB clip. Trammell has shown off his eye at the plate both in the majors (11.1% walk rate) and in Triple-A (14%).

Trammell’s once better-than-average speed has declined, as Statcast ranked him in just the 43rd percentile of MLB players in average sprint speed last year. His defensive grades from metrics like Outs Above Average and Defensive Runs Saved haven’t lined up with scouting reports that pegged him as a potentially plus defender in the outfield, either. Trammell has probably hit for more power than was expected early in his prospect days. His .368 slugging isn’t much to look at, but when considering his low batting average, he’s sitting on a .200 ISO in his big league career. He’s also popped 38 homers in his 812 Triple-A plate appearances.

His role with the Dodgers is yet to be determined, though fellow lefty-swinging outfielder Jason Heyward has been dealing with a back issue. If Heyward needs to miss any time, Trammell could step into his role as a stopgap until the veteran is able to return.

AL West Notes: Verlander, García, Santos, Brash, Sasaki

By Leo Morgenstern | April 1, 2024 at 10:46pm CDT

A pair of Astros starting pitchers are making progress on their way back from injuries. Justin Verlander spoke to reporters (including Chandler Rome of The Athletic) after a successful batting practice session against live hitters on Monday. He believes his next step will be a minor league rehab assignment. Manager Joe Espada provided a similar update, telling Brian McTaggart of MLB.com that his ace “should be ready to go out on a rehab assignment” as long as he “comes back tomorrow feeling well.” Espada suggested Verlander would need more than one rehab appearance before he can return to the Astros, but the skipper did not provide an exact timeline for the three-time Cy Young winner’s return. Verlander has recovered from the shoulder injury that kept him on the sidelines this spring. Still, he needs more time to build up his arm strength before pitching in an MLB game.

Meanwhile, Luis García has begun to throw off a mound, and Espada says the righty is “ahead of schedule” in his recovery from a UCL injury (per Rome). The 27-year-old underwent Tommy John surgery last May. While he still has plenty of work to put in before he can return to the majors, the Astros are hopeful he can rejoin the rotation by July if all goes well (per Matt Kawahara of the Houston Chronicle). Over 64 games (62 starts) from 2021-23, García pitched to a 3.63 ERA and 3.86 SIERA.

More news from around the AL West…

The Mariners received some good news today when reliever Gregory Santos’ MRI came back clean (per Adam Jude of the Seattle Times). He had been dealing with a flareup of inflammation in the strained lat that kept him out for all of spring training. According to Ryan Divish of the Seattle Times, Santos needed the MRI to come back clean in order to resume his throwing program; the hard-throwing right-hander has now begun “light baseball activities” (per Jude). The Mariners have not yet provided a timeline for his return, but they are surely hoping to get him back sooner rather than later. Santos pitched to a 3.39 ERA and 3.32 SIERA in 60 games for the White Sox last season.
In other Mariners bullpen news, Matt Brash is making progress as he recovers from right elbow inflammation. While Mariners GM Justin Hollander would not provide an exact timeline for any of his injured arms, he suggested that Brash is the furthest along in his rehab (per Jude). Like Santos, Brash is a hard-throwing right-hander coming off a breakout year. In 78 games last season, he posted a 3.06 ERA and 2.86 SIERA, winning nine games and collecting 24 holds.
Eight teams recently sent representatives to watch NPB ace Roki Sasaki pitch in Japan. The Dodgers, Cardinals, Mets, and Yankees were previously reported to be four of those clubs, and now Evan Grant of The Dallas Morning News reveals that a scout from the Rangers was also in attendance. That leaves three remaining mystery teams present at Sasaki’s latest starts for the Chiba Lotte Marines.
