Mariners Win Arbitration Case Against Diego Castillo

By | at

The Mariners have won their arbitration case with reliever Diego Castillo, reports Mark Feinsand of MLB.com (Twitter link). He’ll be paid at the team’s filing rate of $2.95MM rather than his camp’s requested $3.225MM figure.

Castillo has played a season and a half in the Pacific Northwest. Acquired from the Rays at the 2021 trade deadline, he’s provided the M’s with 76 1/3 innings of 3.42 ERA ball. That includes a 3.64 mark over 54 1/3 frames last season, with the big righty striking out a solid 23.9% of opponents against a slightly elevated 9.9% walk percentage. That’s not quite the level he’d managed during his best seasons in Tampa Bay but has still made him a solid high-leverage option for manager Scott Servais.

He’ll again take on some key innings as part of what should be another strong Seattle relief unit. Andrés Muñoz, Paul Sewald, Penn Murfee and Matt Brash are among the other righties who could log key work. The M’s don’t have an established left-hander in the group — offseason waiver claims Tayler Saucedo and Gabe Speier are the only two lefty relievers on the 40-man roster — but the unit was nevertheless among the league’s top ten in both ERA and strikeout percentage last season.

Castillo has between four and five years of MLB service time. He’ll be eligible for arbitration again next winter before qualifying for free agency over the 2024-25 offseason, at which point he’ll be entering his age-31 season. Seattle still has pending arbitration hearings with Teoscar Hernández and Dylan Moore.

Mariners, Kyle Tyler Agree To Minor League Contract

By | at

The Mariners are signing reliever Kyle Tyler to a minor league deal, MLBTR has learned. The Nello Gamberdino client hit free agency last summer after being released by the Giants.

Tyler’s name frequented the MLBTR pages last offseason. The right-hander bounced around to a number of teams in rapid succession, essentially serving as the 41st man on a handful of clubs’ rosters. A career-long member of the Angels through the lockout, he lost his 40-man spot with Anaheim during Spring Training. Within a few weeks, he’d go to the Red Sox, Padres, back to the Angels and then back to the Padres via waivers.

While Tyler held a 40-man spot in San Diego into early June, he was again designated for assignment at that point. He finally cleared waivers and was outrighted to Triple-A. The Padres re-selected him onto the roster within a few days, then waived him again a couple weeks thereafter. Tyler cleared and became a minor league free agent (as was his right after a second career outright assignment) and signed a non-roster deal with the Giants. He made only four Triple-A appearances in the San Francisco organization before being released.

It was a circuitous route, one Tyler acknowledged at the time wasn’t a particularly pleasant experience. The 26-year-old got into just two MLB games last year, both with San Diego. He spent the majority of the season with the Friars’ top affiliate in El Paso, posting a 4.98 ERA through 21 2/3 innings of relief. He struck out 29% of batters faced with an excellent 58.7% grounder percentage for the Chihuahuas, though he also walked over 20% of opponents.

The free passes were uncharacteristic, as Tyler had never previously walked more than 8.6% of batters faced at a minor league stop. Prospect evaluators had pointed to his above-average control in pegging him as a potential depth starter, though he’s settled into a relief role for the past couple seasons.

Tyler joins Taylor Williams, Casey Sadler, Riley O’Brien and José Rodríguez as righty relievers with MLB experience who’ll serve as non-roster depth options for the Mariners. The M’s have a very deep bullpen that isn’t likely to afford many early opportunities to that group. Tyler will likely start the year at Triple-A Tacoma and try to vie for a midseason job. He still has two option years remaining, so the M’s could shuttle him between Seattle and Tacoma if he secures a 40-man roster spot.

Mariners Re-Sign Taylor Williams To Minor League Contract

By | at

The Mariners announced a number of non-roster Spring Training invitees this afternoon. Among those in camp are reliever Taylor Williams and catcher Brian O’Keefe, meaning both have signed minor league deals to return to the organization.

Williams has 97 MLB appearances to his name, splitting that over four clubs. The right-hander broke into the big leagues with Milwaukee and landed with Seattle for the 2020 campaign. He struck out 19 in 13 2/3 innings through the first month-plus of the shortened season. With Seattle out of playoff contention, they flipped him to the Padres in a deal that netted then-prospect Matt Brash. It proved a coup for Seattle, as Brash quickly blossomed into a highly-regarded talent and now looks a key piece of the Seattle relief corps moving forward.

San Diego got just five outings from Williams, as he lost most of the 2021 season battling a knee injury. The Friars waived him in September 2021, and he had brief stints in the Marlins’ and Giants’ organizations before returning to the Mariners via minor league deal last summer. The 31-year-old posted a 1.14 ERA over 23 2/3 innings for Triple-A Tacoma, racking up grounders at an incredible 60% clip. With the Mariners overloaded with bullpen depth, he never got an MLB look but impressed the front office enough to get another crack this spring.

Seattle still has an excellent relief corps. The offseason trade of Erik Swanson in the Teoscar Hernández deal subtracted one player from the mix, but Seattle added the out-of-options Trevor Gott on a free agent contract. He joins Paul Sewald, Andrés Muñoz, Diego Castillo, Penn Murfee and Brash as virtual locks for the season-opening group. Matt Festa is out of options himself and probably cracks the roster, while one of Marco Gonzales or Chris Flexen could take a long relief role if not traded before Opening Day given Seattle’s rotation depth. The M’s also have offseason trade acquisition Justin Topa and nabbed Tayler Saucedo off waivers from the Mets today.

That’s a deep collection of arms, meaning Williams and other non-roster invitees like Casey Sadler, Nick Margevicius, Ryder Ryan and Riley O’Brien could have an uphill battle to the roster. Most of that group is likely to start the season with the Rainiers. Williams is out of options himself, so if he cracks the MLB roster at any point, he’d have to stick in the majors or be made available to other clubs via trade or waivers.

O’Keefe is a 29-year-old backstop who played in two games for the M’s last year. He picked up a hit and a walk in his first four MLB plate appearances. The righty-swinging catcher had a decent .253/.330/.449 line with 13 homers over 352 trips to the dish with Tacoma last year. He joins Jacob Nottingham as non-roster catchers with previous big league experience. Seattle has Cal Raleigh and Tom Murphy as their catching duo but no additional depth on the 40-man at the moment.

Mariners Claim Tayler Saucedo, Designate J.B. Bukauskas

By | at

The Mariners announced that they have claimed left-hander Tayler Saucedo off waivers from the Mets. He was recently designated for assignment when the Mets signed Tommy Pham. In a corresponding move to get Saucedo onto Seattle’s roster, right-hander J.B. Bukauskas was designated for assignment.

Saucedo, 30 in June, was a Blue Jays draftee who cracked that club’s roster midway through the 2021 season. He’s since logged 28 1/3 innings in the big leagues with a 5.40 ERA. He’s gotten much better results in the minors, having posted a 2.11 ERA over the past two years while striking out an incredible 35.7% of batters faced. He’s put up strong ground ball rates in both the majors and minors but the strikeouts are the major difference maker so far as he’s only punched out 15.3% of big league hitters.

Despite the lack of results in the majors to this point, teams seem to be willing to take a shot on Saucedo based on his strong work down on the farm. The Mets claimed him off waivers from the Jays in November but he lost his spot last week with the Mariners now the beneficiary. Saucedo still has a couple of option years remaining and can be sent down to the farm, if needed. He’ll join Gabe Speier and Brennan Bernardino as southpaw relief arms on the club’s roster.

As for Bukauskas, 26, this ends a very short stay on Seattle’s roster, as he was just claimed off waivers from the Diamondbacks two weeks ago. A former first round pick and exciting starting pitching prospect, he struggled with control and was moved to a relief role in recent years. He made 21 major league appearances in 2021 but struggled and posted a 7.79 ERA in that small sample. He’s had much better results in the minors over the past couple of years but hasn’t been able to log significant time due to injuries. He threw 35 minor leagues innings over 2021 and 2022 with a 3.09 ERA, with most of that time spent in the hitter-friendly Pacific Coast League. He struck out 27.5% of batters faced while walking 5.8%. That small workload is due to a strain in his throwing elbow in 2021 and a strain in the teres major muscle in his shoulder last year.

The Mariners will now have a week to trade Bukauskas or pass him through waivers. He still has one option year left, meaning that an interested club could put him on their 40-man and wouldn’t necessarily have to keep him on the active roster. Based on that fact, as well as his youth and previous prospect pedigree, it’s possible that he could have a new club yet again before Spring Training kicks off in two weeks.

Dipoto: Mariners Likely Done Adding To Roster Before Camp

By | at

Mariners president of baseball operations Jerry Dipoto appeared on the latest Locked On Mariners podcast with Ty Dane Gonzalez and Colby Patnode and offered a fairly thorough review of the club’s offseason strategy and overall roster makeup leading into the 2023 campaign. First off, they’re likely done spending for the time being …

“We might wind up coming up with a late trade like we did a year ago with Eugenio Suarez and Jesse Winker by way of Cincinnati,” said Dipoto. “We could pick up a couple of extra NRIs, the non-roster invites … we’re constantly trying to add to the depth of what we go to Spring Training with. But if I had to bet on anything major happening before we step foot on the field, I’d bet against it at this point. And we’re comfortable with that. We feel like we have improved this team.”

Winker is gone after one highly disappointing season in Seattle, having been dealt to the Brewers in December as part of a package for rangy second baseman Kolten Wong. Among the other newcomers: Teoscar Hernandez, acquired via trade from the Blue Jays in November. AJ Pollock, brought in on a one-year, $7MM free agent contract earlier this month. And also Tommy La Stella, signed to a one-year major league pact 10 days ago.

Dipoto views this as more of a deep and dynamic group than what the Mariners put out there in 2022, when they snapped the longest postseason drought in North American professional sports before getting swept by the eventual World Series-champion Astros in the ALDS. Most of the additions have been on the position-player side, which makes sense given that Seattle finished 14th last year in combined team OPS at .704 and 8th in combined team ERA with a mark of 3.59.

Hernández will be the new starter in right field, with near-unanimous 2022 AL Rookie of the Year Award winner Julio Rodríguez locked into center for possibly the next decade-plus. Dipoto expressed hope that Jarred Kelenic can take a step forward and grab the reins in left. Taylor Trammell figures to factor into the outfield mix as well, and so can the versatile Dylan Moore if he makes a full recovery from offseason surgery to address a core injury. Moore will be a little behind his teammates when Spring Training officially gets underway next month, which maybe gives young speedster Cade Marlowe a chance to shine.

The infield looks set with Ty France at first base, Wong sliding into second, Suarez handling third, and J.P. Crawford returning at short. La Stella will back up a couple of those spots along with Moore and Sam Haggerty. Cal Raleigh should get the majority of the action at catcher, with a healthier Tom Murphy sitting behind him in reserve. “All baseball activity is in play now,” Dipoto said of Murphy, who appeared in only 14 games in 2022 because of a left shoulder injury that required season-ending surgery in June. “His workouts have gone extremely well … We missed Murph.”

The bullpen largely has the same dominant names and faces — Paul Sewald, Andres Munoz, Diego Castillo, Matt Brash, Penn Murfee — that helped produce a combined 3.33 reliever ERA (6th in MLB) and 583 strikeouts in 544 innings last season. Justin Topa, recently picked up from Milwaukee, drew praise from Dipoto as an under-the-radar breakout candidate in that department.

The biggest camp battle, as things stand right now, is going to be for the final spot in the starting rotation. Chris Flexen and Marco Gonzales are the frontrunners, but Dipoto sees Emerson Hancock, Bryce Miller, Taylor Dollard and Bryan Woo knocking on the door as the season plays out. Luis Castillo, Logan Gilbert, Robbie Ray and George Kirby can be penciled into the top four spots, pending any sudden injuries.

Mariners Release Jason Vosler

By | at

TODAY: The Mariners have released Vosler, in the latest update to his MLB.com page.  The circumstances behind the abrupt release aren’t known, though in some similar instances with other players, the move indicates that the player has instead agreed to a guaranteed deal with a team overseas.

JANUARY 25: The Mariners have signed infielder/outfielder Jason Vosler to a minor league contract, according to his transactions tracker at MLB.com. Volser will presumably receive an invitation to major league Spring Training.

Vosler, 29, has been an up-and-down player with the Giants for the past two years. In 2021, he got into 41 games and hit .178/.256/.356 for a wRC+ of 63. He was much better in 72 Triple-A games, with a line of .295/.385/.529, 125 wRC+. In 2022, that split was bizarrely reversed, as he produced a .242/.311/.433 line in the minors but hit .264/.342/.469 in the big leagues. The former line led to a wRC+ of 82 whereas he had a 127 wRC+ in the majors. Defensively, Vosler has played all over, having lined up at all four infield positions and the outfield corners. Despite that versatility and some positive results at the plate, the Giants non-tendered him at season’s end.

For the Mariners, their infield will likely consist of Eugenio Suárez, J.P. Crawford, Kolten Wong and Ty France from left to right on most nights. Tommy La Stella is sort of in the mix but he’s coming off an injury-plagued year where he hardly took the field. The outfield will have Julio Rodríguez, Teoscar Hernández and AJ Pollock, as well as young players that aren’t yet established like Jarred Kelenic and Taylor Trammell.

Vosler will likely be competing with Dylan Moore and Sam Haggerty to serve in a bench/utility role, with injuries possibly opening a path to get onto the roster as the season rolls along. Vosler hits from the left side and has a noticeable platoon split in his limited big league time so far, 102 wRC+ against righties but a 78 otherwise. He could potentially be used situationally since the club has a bunch of righties set to be in their regular lineup. If Vosler does get selected to the roster, he still has an option year remaining and less than a year of service time, allowing the M’s to cheaply retain him for the foreseeable future if they so choose.

Mariners Outright Justus Sheffield

By | at

The Mariners announced that left-hander Justus Sheffield has cleared waivers and been outrighted to Triple-A Tacoma.

Sheffield, 27 in May, was a first round draft pick and was previously considered one of the top prospects in baseball. Selected 31st overall by Cleveland in 2014, went to the Yankees in 2016 as part of the Andrew Miller trade and then went to Seattle in the 2018 James Paxton deal. Baseball America placed him on their top 100 list for four straight years beginning in 2016, including placing Sheffield in the top 50 for the latter two years of that stretch.

Unfortunately, he hasn’t been able to deliver on that hype so far. He’s pitched 186 innings in the big leagues over the past five seasons with a 5.47 ERA, 18.2% strikeout rate and 10.6% walk rate. His 49.5% ground ball rate is strong but the results have been poor otherwise. His work in the minors hasn’t inspired much confidence either, as he registered a 6.99 ERA over 24 Triple-A starts last year.

Those poor results nudged him off the roster when the Mariners signed Tommy La Stella last week. None of the 29 other clubs were willing to commit a roster spot to Sheffield so he’ll stick with the M’s as non-roster depth. Players with over three years of service time or a previous career outright can reject an outright assignment and elect free agency, but Sheffield doesn’t meet either qualification. If he earns his way back onto the roster, he still has one option year remaining.

Health Notes: King, Antone, Sewald

By and | at

Yankees righty Michael King, who missed the final two and a half months of the 2022 season due to a fractured right elbow, tells The Athletic’s Brendan Kuty that he expects to be ready for Opening Day and anticipates being deployed as a multi-inning reliever in 2023. The 27-year-old King was in the midst of a breakout season when he suffered his ill-timed injury. Prior to landing on the IL, he’d pitched to an outstanding 2.29 ERA and whiffed 33.2% of his opponents against a tidy 8% walk rate. The righty was also touting a career-high 47% grounder rate and career-low 0.53 HR/9 mark.  His 96.5 mph average fastball was the best of his career. Just three weeks ago, Opening Day was reported to be a slightly optimistic target for King, so his firmer confidence in his ability to be ready for the season is a welcome development for the Yankees and their fans.

A few more health/injury updates of note from around the league…

  • Reds reliever Tejay Antone’s offseason throwing program has been slowed by a forearm issue, reports Mark Sheldon of MLB.com, though it’s not believed to be related to the right-hander’s surgically repaired elbow. Antone was having one of the best seasons of any reliever in baseball before undergoing Tommy John surgery in 2021. The former fifth-rounder turned in an outstanding 2.14 ERA with a gaudy 32.8% strikeout rate against a 10.2% walk rate while holding opponents to a comically inept .152/.258/.250 batting line through 128 plate appearances. If healthy, he could quickly ascend the bullpen hierarchy and return to high-leverage work in 2022. Antone has another three seasons of club control remaining and is set to earn just $770K this season. As such, he’ll quite likely garner plenty of summer trade interest if he’s back to form, given the state of the Reds’ rebuild.
  • Mariners reliever Paul Sewald might not be ready for the beginning of Spring Training, as Corey Brock of The Athletic reports that the righty underwent a “minor clean-up of his heel and elbow.” The exact timeline of the procedure or recovery aren’t known, though Brock suggests Sewald should still be ready to go by Opening Day. Turning 33 in May, Sewald is enjoying a late-career bloom. After posting underwhelming numbers over the 2017 to 2020 stretch, he has a 2.87 ERA in 127 appearances over the past two campaigns, striking out 34.8% of batters in faced in that time against an 8.1% walk rate. He and the club agreed to a $4.1MM salary for the upcoming campaign and he’ll have one further arbitration season in 2024 before he’s slated for free agency.

Mariners Hire Mike Freeman As Double-A Manager

By | at

The Mariners announced last night that former infielder Mike Freeman has been hired as the manager of their Double-A affiliate, the Arkansas Travelers. The 35-year-old Freeman was playing in the big leagues as recently as 2021 but did not sign for the 2022 season. It now sounds as though his days as an active player have drawn to a close.

“I am excited to be back in the Mariners organization as the manager of the Arkansas Travelers,” Freeman said in the Travelers’ press release. “We have a great staff, and I am looking forward to assisting them in the development of our players.”

Freeman spent 11 years in pro ball after being drafted three times as an amateur. The Padres selected him out of high school in the 41st round back in 2006, but Freeman declined to sign and instead attended Clemson, where he was drafted by the D-backs in the 36th round after his junior season. He again declined to sign, going back for his senior year and playing well enough for the D-backs to select him again, this time in the 11th round.

Freeman appeared in parts of six big league seasons between Cleveland, Seattle, Arizona, Chicago (Cubs), Cincinnati and Los Angeles. His best season came in 2019 with Cleveland, when he logged career-highs in games played (75) and plate appearances (213), hitting .277/.362/.390 along the way. The bulk of his time in the big leagues was spent as a utilityman, however, and Freeman will retire as a player with at least one inning at every position on the diamond other than catcher (including 3 1/3 innings of mop-up duty on the mound).

In all, Freeman hit .225/.306/.306 in 193 big league games and also logged a .298/.370/.417 batting line in more than 2000 Triple-A plate appearances. He’ll be joined on the Travelers’ coaching staff by another former big league infielder, Shawn O’Malley, who played parts of three MLB seasons (2014 Angels, 2015-16 Mariners) and is in his second season as the club’s hitting coach.

Mariners Outright Alberto Rodriguez

By | at

The Mariners announced that minor league outfielder Alberto Rodriguez has gone unclaimed on waivers. He’ll stick in the organization at High-A Everett on outright assignment.

Rodriguez entered the professional ranks as an amateur signee of the Blue Jays in 2017. He was dealt to Seattle three years later as part of the trade that sent Taijuan Walker to Toronto. The left-handed hitter drew some attention from prospect evaluators for his power upside and was regarded as a possible future right fielder. The M’s put him on their 40-man roster last winter to keep him out of the Rule 5 draft.

He spent his entire age-21 campaign in High-A on optional assignment. Rodriguez hit .261/.336/.396 with 10 home runs across 527 plate appearances. That’s decent production but not overwhelming for a bat-first prospect. More concerning, he went down on strikes in more than 26% of his trips. That dealt enough of a hit to Rodriguez’s long-term value that Seattle took him off the 40-man to claim J.B. Bukauskas last week.

The M’s took the risk of losing Rodriguez, but no other team was willing to devote him a 40-man spot either. He’ll remain in the system as an upside flier for the Seattle player development staff, where the M’s can monitor the progress of his bat-to-ball skills as he tries to work his way to the big leagues.
