Austin Nola To Become Mariners’ Bullpen Coach

By | at

Catcher Austin Nola is expected to rejoin Seattle’s organization as bullpen coach, reports Bob Nightengale of USA Today. Nola will be released from the minor league deal he signed with Atlanta last month, adds Nightengale. The transition into coaching suggests Nola is wrapping up his playing career after six MLB seasons. Seattle has yet to announce the hiring.

Tony Arnerich served as Seattle’s bullpen coach and catching instructor last season. He was initially hired as hitting coach in 2022, a role he held for two seasons. Arnerich was moved to the bullpen position in 2024. The Mariners have yet to announce any change to Arnerich’s role or any other adjustments to the coaching staff.

Nola was drafted by the Marlins in 2012. He spent seven seasons in the minors with the organization, never reaching the big leagues. Nola signed a minor league deal with the Mariners ahead of the 2019 season, and he would make his major league debut later that year. He stepped into semi-regular playing time in a versatile role with Seattle, making starts at catcher, first base, second base, third base, and right field. Nola slashed a solid .269/.342/.454 over 79 games that season.

Nola was dealt to the Padres in the middle of the 2020 campaign. The seven-player deal featured mostly part-time players, though Seattle netted reliever Andres Munoz in the return. Munoz had just 23 MLB innings under his belt at the time, but would go on to become a fixture in the Mariners’ bullpen, earning All-Star nods the past two seasons.

San Diego received decent production from Nola across multiple seasons. He posted a 101 wRC+ over 56 games in 2021. Nola mostly played catcher, along with a handful of appearances in the infield. Nola took over as the Padres’ primary backstop in 2022, setting career highs in games (110) and plate appearances (397) while recording a .649 OPS. After hitting just .146 over 52 games in 2023, Nola found himself in Triple-A. He didn’t reach the majors in 2024, spending the year in Kansas City’s minor league system. Nola latched on with Colorado this past season. He went 7-for-41 in a brief stint with the Rockies. Nola was designated for assignment and then outrighted off the 40-man roster in August.

If this is it for Nola, he’ll conclude his playing career with a .247/.323/.364 slash line across 1,237 plate appearances. He hit 24 home runs and chipped in three stolen bases.

Guardians Hire Andy McKay As Field Coordinator

By | at

The Guardians are adding Andy McKay to their coaching staff with the title of field coordinator, reports Ken Rosenthal of The Athletic. That job was previously held by Kai Correa, who departed last month to become bench coach for the Mets.

McKay has had an interesting career, oscillating between coaching and front office roles. He had been a coach in college ball for a number of years, before working for the Rockies in the minors as peak performance coordinator. Then he spent a long time working in the Mariners’ player development department, getting hired in October of 2015. That was not long after Jerry Dipoto had become Seattle’s general manager. Dipoto and McKay had worked together with the Rockies.

Going into the 2022 season, McKay was added to Seattle’s uniformed coaching staff with the title of major league coach and senior director of baseball development. However, as noted by Ryan Divish of The Seattle Times, he had to pivot back to the front office during spring training when his replacement left. One year later, he was promoted to assistant general manager. A year ago, the Mariners added vice president to his title.

“It’s sad for me, but I’m thrilled for him,” Mariners general manager Justin Hollander said of today’s news, per Divish. It’s noted by Divish that McKay has held his desire to coach since his collegiate coaching days. He almost got the chance with Seattle a few years ago but it didn’t work out.

He’ll now get to join a big league coaching staff in Cleveland, working under manager Stephen Vogt. The Guardians also lost their bench coach/associate manager when Craig Albernaz became manager of the Orioles, so perhaps another hiring is still to come.

Mariners, Randy Dobnak Agree To Minor League Deal

By | at

The Mariners and right-hander Randy Dobnak have agreed to a minor league deal with an invite to big league camp, reports Jeff Passan of ESPN. The righty is represented by Gaeta Sports Management.

Dobnak, 31 in January, just got to the end of an early-career extension that didn’t really pan out. Once an undrafted free agent who was playing indy ball and driving an Uber, he landed with the Twins and climbed all the way up to the majors. Over the 2019 and 2020 seasons, he tossed 75 innings for Minnesota, allowing 3.12 earned runs per nine. His 15.7% strikeout rate was pretty low but he posted a 5.7% walk rate and also got grounders at a high rate of 58.8%.

At the start of the 2021 season, the Twins and Dobnak agreed to a five-year, $9.25MM extension. From the team perspective, that was a tiny amount of money, even for a lower-spending club like the Twins. But for Dobnak, considering his humble origins, that was massive.

Unfortunately, it didn’t really work out for the club. Dobnak’s ERA shot up to 7.64 in 2021. He has largely been kept in the minors since then. He didn’t pitch in the big leagues at all in 2022 or 2023, followed by just five appearances last year and one in 2025. The Twins shipped him to the Tigers at the deadline as part of the Chris Paddack trade, seemingly just to get the remainder of the money owed to Dobnak off their books. The Tigers kept him in the minors and then declined a club option for 2026, giving Dobnak a $1MM buyout instead.

For the Mariners, there’s no harm in bringing him aboard via a minor league deal, giving them some non-roster pitching depth. Dobnak’s recent minor league work hasn’t been great but he has continued to get grounders on roughly half the balls in play he’s allowed. If he’s added to the 40-man roster at any point, he’s still optionable. That’s because the Twins usually outrighted him completely off the 40-man roster, as opposed to just optioning him to the minors.

Mariners Claim Ryan Loutos From Nationals

By | at

The Mariners claimed reliever Ryan Loutos off waivers from the Nationals, per a team announcement. The move brings Seattle’s 40-man roster count to 38.

Loutos joins the fourth organization of his career. He’s a former undrafted free agent signee of the Cardinals who debuted with St. Louis in 2024. He made three appearances. The Cards designated him for assignment in April and traded him to the Dodgers for cash. Loutos didn’t spend much time in L.A. (though he’ll collect a World Series ring for his brief stop), as he made just two big league appearances. The Dodgers lost him on waivers to the Nats in June.

The 6’5″ righty pitched ten times for the Nationals. He allowed 16 runs (12 earned) with six walks and strikeouts apiece over nine innings. He had a better season in Triple-A, where he combined for 43 2/3 innings of 3.50 ERA ball. Loutos recorded a league average 22.8% strikeout rate while walking a little over 10% of opponents in the minors. He averages 95 MPH on his heater and has a slider and changeup.

There’s minimal cost for the Mariners in using an open roster spot to stash Loutos as bullpen depth. There’s no guarantee he’ll stick on the 40-man all offseason. If he does, he can be sent to Triple-A Tacoma without going on waivers. Loutos still has one minor league option remaining.

Mariners Acquire Cole Wilcox From Rays

By | at

The Mariners have acquired right-hander Cole Wilcox from the Rays in exchange for cash considerations, per announcements from both clubs. The righty had been designated for assignment by the Rays earlier in the week. The M’s had 40-man space thanks to players recently becoming free agents.

Wilcox, now 26, came to the Rays in the December 2020 trade which sent Blake Snell to San Diego. The righty required Tommy John surgery in September of 2021, which wiped out most of his 2022. In the following two years, the Rays kept developing him as a starter in the minors, with fairly uninspiring results. In 250 1/3 innings over those two seasons, he had a 4.28 earned run average, 19.8% strikeout rate and 8.3% walk rate.

In 2025, he was used primarily as a reliever, which seemed to help him find a new gear. He tossed 58 1/3 innings over 39 appearances on the farm with a 3.70 ERA. His 10.8% walk rate was a bit high but he struck out 25.1% of batters faced and got grounders on 50.3% of balls in play. The Rays added him to the 40-man in September and he tossed one big league inning, allowing three earned runs.

With the injured list going away this week, the Rays needed to open up some roster space and Wilcox was one of the casualties. Conversely, the Mariners had a few open roster spots and have used one to grab Wilcox. Seattle has a pretty good track record of coaxing good results from low-profile pickups like this, so it wouldn’t be a surprise to see Wilcox flourish with his new club. Even if that is setting expectations too high, he has a full slate of options and can serve as a depth arm in Triple-A.

Jorge Polanco Declines Player Option

By | at

Infielder Jorge Polanco is now a free agent, reports Jon Heyman of The New York Post. Heyman says Polanco is turning down an $8MM mutual option but Polanco actually converted that to a $6MM player option during the season. Regardless of the details, the larger point is that Polanco is heading back to the open market, collecting a $750K buyout on his way out the door.

The decision is not a surprise. Polanco is coming off a tremendous bounceback season. He stepped to the plate 524 times and hit 26 home runs. His .265/.326/.495 batting line translated to a 132 wRC+, his best offensive performance over a full season in his career.

It wasn’t a perfect season. Ongoing knee problems kept him mostly in the designated hitter spot, though he appeared to get healthier as the year wore on. He made just 34 starts at second base but most of those were after the All-Star break, including 15 in September.

He undoubtedly has more earning power now than he did a year ago, despite being a year older. The aforementioned knee problems limited him to just 118 games with a rough .213/.296/.355 slash line and 93 wRC+. He underwent knee surgery in October. Despite that poor showing and uncertain health status, the Mariners still re-signed him to a one-year deal with a $7.75MM guarantee. That came in the form of a $7MM salary plus a $750K buyout on an $8MM mutual option. Polanco could convert that to a $6MM player option with 450 plate appearances, which he easily topped.

His better platform season and improved health outlook should line him up for a better deal, likely with multiple years, so turning down one year and $6MM is an easy call. The Mariners have interest in bringing him back but he will have other suitors as well and Seattle may be prioritizing a Josh Naylor reunion.

Mariners Exercise Andres Munoz’s 2026 Club Option

By | at

The Mariners exercised their $6MM club option on Andres Munoz’s services for the 2026 season, according to reporter Francys Romero.  The total value of the option is actually $7MM, as Munoz unlocked four $250K bonuses based on his number of games finished in 2025.

There was zero suspense in the Mariners’ decision, as Munoz has become one of baseball’s top closers.  An All-Star in each of the past two seasons, Munoz posted a 1.73 ERA and 32.7% strikeout rate over 62 1/3 innings while recording 38 saves.  While he has a penchant for issuing walks, that’s the only blemish on an otherwise excellent resume for the hard-throwing righty.

The four-year, $7.5MM extension Munoz signed with the Mariners back in November 2021 has proven to be quite a bargain for the team.  The guaranteed portion of the extension is now through, but the M’s still control Munoz through 2028 via three club option years.  The 2027 option is worth $8MM and the 2028 option is worth $10MM, with more bonus money available based on games finished.

Between exercising Munoz’s option and declining their end of Mitch Garver’s mutual option yesterday, the Mariners have already completed a pretty easy slate of club-related options.  The one remaining option outside of the team’s hands is Jorge Polanco’s $6MM player option for 2026, and it is expected that Polanco will choose to re-enter free agency on the heels of a strong season.

Mariners Decline Mutual Option On Mitch Garver

By | at

Catcher Mitch Garver is headed into free agency after his mutual option with the Mariners was declined, according to an announcement by the Major League Baseball Players Association this morning. The union didn’t specify which side declined its half of the option, though MLBTR has confirmed that it was (rather unsurprisingly) the Mariners who turned down their half. Garver will be paid a $1MM buyout rather than a $12MM salary for 2026.

That the option was declined is hardly a surprise; mutual options are very rarely exercised to begin with, and the Mariners have long been expected to decline their end of the option. Garver initially signed in Seattle on a two-year, $24MM deal. That remains the club’s largest expenditure on a free agent hitter under president of baseball operations Jerry Dipoto, though they’ve invested significantly more than that on extensions for players like Julio Rodriguez and Cal Raleigh.

Unfortunately, Garver’s deal with the Mariners did not go especially well. He slashed a lackluster .187/.290/.341 in 201 games as a Mariner, good for a wRC+ of just 88. While he did slug 24 homers in 720 plate appearances and walk at a healthy 11.5% clip, he struck out 29.6% of the time while posting a line drive rate well below his career norms. That combination of an elevated strikeout rate and deflated BABIP was simply too much for his power and discipline to overcome when it came to being an above-average hitter with Seattle.

While an 88 wRC+ is below average, it’s still generally acceptable offensive production from a backup catcher, which is the role Garver found himself in this year for the most part. He had not been paid as a backup, however, and the Mariners envisioned him as a primary DH who could also take occasional starts behind the plate at the time of the signing. There was some logic in signing Garver for that role, given that he had just put together an explosive 2023 season with the Rangers where he slashed .270/.370/.500 with 19 homers in just 87 games, but the results of that deal are undeniably disappointing.

Now entering his age-35 season, Garver returns to free agency in a very different spot than last time. No team is going to invest in a multi-year deal to make him their starting DH. That doesn’t mean a big league deal is off the table, however, and Garver should benefit substantially from a weak catching market. While Garver grades out as a below-average defender behind the plate across the board, the pop he’s displayed in his bat over the years could be enticing to a team that needs to add power to the lineup and has a hole behind the plate. The veteran is far from the first hitter to struggle in the pitching-friendly environment of T-Mobile Park, and teams might think that getting him out of Seattle could help him rebound somewhat offensively.

In a market with virtually no depth behind J.T. Realmuto, Danny Jansen, and Victor Caratini, it’s not at all hard to see a catching-hungry team bringing Garver into the fold. The Padres, Astros, and Rays are known to be in need of catching help, and they could be joined by teams like the Rangers and Red Sox depending on the decisions those clubs make on arbitration-level players who could be possible non-tender or trade candidates.

Yoervis Medina Passes Away

By | at

Former major league pitcher Yoervis Medina has passed away. Reports out of his native Venezuela indicate that authorities believe Medina suffered a heart attack while he was driving, leading to a fatal car accident. He was 37 years old.

Medina pitched for the Mariners and Cubs from 2013-15, working 146 innings across an identical number of games. He posted a 3.08 career ERA with a 23.1% strikeout rate along with a 12.4% walk rate. Most of his success came in his first two seasons, as Medina pitched to a 2.81 ERA with a 24.3% strikeout rate and 12.6% walk rate in 125 innings for the Mariners from 2013-14. In that span, he ranked 34th out of 109 qualified relievers in ERA and ranked 21st with a 53.5% ground ball rate.

He was traded to the Cubs in May 2015 for Welington Castillo and pitched in five games for them with a 7.00 ERA, but he wound up spending most of the season in the minors. That was followed by brief stints in the Pirates and Phillies organizations in 2016, neither of which resulted in a big league call. Medina then pitched in the Venezuelan winter league from 2016-20 before moving to the Italian Baseball League in 2023 and the Czech Baseball Extraliga in 2024.

Medina was teammates in Seattle with Jesús Montero, who was tragically killed in a motorcycle crash earlier this month. We at MLB Trade Rumors send our condolences to Medina’s family, friends, loved ones and former teammates.

Bryce Miller Expected To Avoid Elbow Surgery

By | at

Seattle right-hander Bryce Miller is not expected to need elbow surgery this offseason, reports Adam Jude of the Seattle Times. Miller had multiple stints on the injured list this past season due to elbow inflammation. He returned for the final six weeks of the regular season and made three starts in the playoffs. “I finished the year the best I felt all year — three good starts, I felt like,” Miller told Jude. “My body and my arm feel good, so just get better, get fully healthy and be ready to go from Day 1 next year.”

Miller was diagnosed with a bone spur in his elbow and received a PRP injection in early June. He relayed to Jude that he has an upcoming appointment to determine the next steps in treatment. Miller said the likely route is a gel cortisone injection early this offseason, and potentially another one at the start of spring training. “Now that we know how to deal with the bone spur, we can figure out what we need to do exactly with it and go from there,” Miller told Jude. He added that he’d be “surprised” if the appointment led to an invasive procedure.

The elbow injury seemed to derail the early portion of Miller’s 2025 campaign. He struggled to a 5.22 ERA through his first eight starts. The control was the biggest red flag. After posting a solid 6.4% walk rate in 2024, Miller nearly doubled that mark to 12.1% over his first 39 2/3 innings. He hit the IL on May 14, though it was a minimum stint. Miller returned at the end of May, but only lasted two starts. He was hammered for eight earned runs over nine innings and headed back to the IL.

The results following Miller’s second absence weren’t much better. He closed the regular season with a 5.62 ERA over eight starts, but there were encouraging signs heading into the playoffs. Miller’s fastball velocity improved by nearly one mph. He cut his walk rate to 6.3%. Miller was mostly done in by a massive 24.5% home run to fly ball rate, which should be expected to regress over a larger sample.

Miller put everything together in the postseason. He limited the Tigers to two runs over 4 1/3 innings in Game 4 of the ALDS. Miller then came through with six dominant innings in a win over Toronto to kick off the ALCS. He returned in Game 5 with four innings of one-run ball, though Toronto’s bullpen couldn’t hold a late lead. Miller’s fastball velocity topped out at 98.1 mph in his second start against the Mariners.

The uneven 2025 season was a disappointing follow-up to a tremendous 2024 for Miller. He built on a solid rookie year, putting together 180 1/3 innings of a sub-3.00 ERA and nearly a strikeout per inning last season. Miller’s 3.85 xFIP and 3.80 SIERA suggested he might not have been as good as his 2.94 ERA, but he looked like a fixture in a talented rotation.

After a remarkably healthy 2024, Seattle’s starters were hampered by injuries this past season. Logan Gilbert spent all of May and part of June on the IL with an elbow flexor strain. George Kirby missed the first two months of the season with shoulder inflammation. Bryan Woo went down with a pectoral injury in September. He was available for just 4 1/3 innings in the playoffs.

Seattle’s rotation led the league in ERA in 2024. The staff slipped to 13th this past season. With Miller managing his elbow injury without surgery, and an offseason for Woo to get back to full health, the rotation should once again be among the best in the league next season. The unit will be key in getting the team back to the postseason in 2026.
