Cubs Outright Tyson Miller

By Darragh McDonald | June 12, 2025 at 6:35pm CDT

Right-hander Tyson Miller has been outrighted by the Cubs to Triple-A Iowa, according to his transactions tracker at MLB.com. That indicates he cleared waivers after being designated for assignment last week. He has the right to elect free agency, though it’s not yet clear if he will exercise that right.

It’s a bit of a surprise to see no one take a flier on Miller as he’s coming off a strong season. He logged 62 innings for the Mariners and Cubs last year, allowing just 2.32 earned runs per nine. His 23% strikeout rate was around league average for a reliever while he only gave out walks to 4.7% of batters faced.

He hasn’t yet had a chance to build on that showing here in 2025. He went to Japan with the Cubs for the Tokyo Series but didn’t pitch in the official big league games. He landed on the injured list due to a left hip impingement prior to domestic Opening Day. He had been rehabbing in recent weeks, with a 2.77 ERA in 13 Triple-A innings, but the Cubs didn’t want to plug him back onto the active roster. Since he’s out of options, that meant bumping him from the 40-man.

It’s possible that major league clubs don’t have much faith in Miller being able to replicate last year’s results. There was likely some luck in his numbers, as his .203 batting average on balls in play and 81.9% strand rate were both to the fortunate side. He also averaged less than 90 miles per hour on both of his fastballs last year, a level where it’s tough to succeed in the modern game.

During his recent rehab outings, though his 2.77 ERA was good, his 19% strikeout rate and 15.5% walk rate were both subpar figures. He managed to keep runs off the board by not allowing any home runs, a feat that would not be sustainable over a larger sample.

It now seems that Miller is destined for more minor league work, since no club is currently willing to give him a big league job. That could be for Iowa if he accepts his assignment or he could head to free agency and look for opportunities elsewhere.

Cubs Designate Tyson Miller For Assignment

By Darragh McDonald | June 5, 2025 at 3:17pm CDT

The Cubs have designated right-hander Tyson Miller for assignment after reinstating him from the 60-day injured list, per Maddie Lee of the Chicago Sun-Times. He had been pitching on a rehab assignment of late but it seems the club didn’t want to add him back to the roster. Since he is out of options, he has been sent into DFA limbo. Their 40-man roster count stays at 40.

Miller, now 29, is a bit of a surprising roster cut. The Cubs acquired him from the Mariners in May of last year, after Seattle had designated him for assignment. But he went on to finish out the year well with the Cubs. Between the two clubs, he finished 2024 with a 2.32 earned run average in 62 innings. He struck out 23% of batters faced and only walked 4.7% of opponents.

He hasn’t yet had a chance to build on that here in 2025. He traveled with the Cubs to Japan but didn’t pitch in the major league portion of the Tokyo Series. He then landed on the IL ahead of domestic Opening Day due to a hip impingement. He was transferred to the 60-day IL in mid-May when Moises Ballesteros was added to the roster.

Miller started a rehab assignment a few weeks ago and has tossed 13 Triple-A innings with a 2.77 ERA. However, his 19% strikeout rate and 15.5% walk rate in that sample are both poor numbers. He’s only been averaging 88.6 miles per hour on his fastball during this rehab, a drop from last year’s 89.6 mph, though that’s perhaps understandable for a guy working back from a long absence.

As mentioned, Miller is out of options. That’s also true for essentially everyone in the Cubs’ bullpen. Of the eight relievers currently on the active roster, Daniel Palencia is the only one who can be optioned to the minors. He has become the club’s closer of late, so he’s not at risk of getting sent down.

Rather than cut anyone currently on the team, the Cubs have decided to cut Miller. He’ll head into DFA limbo, which can last for as long as a week. The waiver process takes 48 hours, so the Cubs could take as long as five days to explore trade interest. Based on the success Miller had last year, it’s possible some other club takes a shot on him, presumably one with a less rigid bullpen construction. He’s still cheap, having not yet qualified for arbitration. Though he’s out of options, he can be controlled for the rest of this season and potentially four more if he sticks somewhere.

Cubs Promote Moises Ballesteros

By Anthony Franco | May 13, 2025 at 3:45pm CDT

May 13: The Cubs have formally selected Ballesteros’ contract, per a team announcement. Happ heads to the 10-day IL, as expected, while a 40-man roster spot was freed up by transferring righty Tyson Miller from the 15-day IL to the 60-day IL. Miller has been out all season due to a hip impingement.

May 12: The Cubs intend to promote catching prospect Moisés Ballesteros for tomorrow’s game against the Marlins, reports Bruce Levine of 670 The Score. Ian Happ is headed to the 10-day injured list, Levine adds. Happ has missed the past three games with oblique discomfort. Ballesteros is not on the 40-man roster, so the Cubs will need to make another move in that regard.

Ballesteros, 21, is one of the top young offensive players in the minors. He’s a career .288/.371/.459 hitter over five professional seasons. His production has remained remarkably consistent as he has climbed the ladder. Ballesteros has posted an OPS above .800 at each stop. That includes a ..311/.368/.477 slash for Triple-A Iowa over the past two seasons.

The lefty-hitting Ballesteros has been on fire to begin this year. He’s out to a .368/.420/.522 start over his first 34 Triple-A contests. He has connected on four homers, seven doubles and one triple while limiting his strikeout rate to a minuscule 10.7% clip. Among hitters with 100+ plate appearances, he’s second in the International League in batting average and ranks among the top 11 hitters in both on-base percentage and slugging. He’s seventh in the league in OPS, and every other player in the top 10 is at least 24 years old.

Unsurprisingly, Ballesteros’ bat has always been his calling card on scouting reports. He was viewed as an advanced hitter when he signed for $1.5MM out of Venezuela during the 2021 amateur signing period. He climbed towards the top of an excellent Chicago farm system as he continued to prove himself against higher-level pitching.

Ballesteros ranked among the league’s Top 100 prospects on offseason lists from Baseball America, MLB Pipeline, Keith Law of The Athletic and ESPN’s Kiley McDaniel. Eric Longenhagen of FanGraphs had him outside his offseason Top 100 but ranked him sixth in the Cubs’ system in December. He is up to 37th overall on BA’s in-season update.

The reports are quite similar across the board. He’s praised for his well-rounded offensive ability but faces questions about his defensive fit. Ballesteros is listed at 5’8″ and has a heavyset build (though he’s reportedly slimmed down a bit in recent years). He’s drawn comparisons to Toronto catcher Alejandro Kirk as a result. Kirk has developed into a solid defensive catcher but faced questions about his glove as a prospect. There are perhaps even greater concerns about Ballesteros’ receiving acumen and ability to control the running game. Opponents have gone 27-31 in stolen base attempts in his 191 1/3 innings as a catcher this season.

It’s unlikely that he’ll get much work behind the dish in the short term. Carson Kelly has obliterated opponents to a .303/.443/.671 slash over his first 25 games. Miguel Amaya has an impressive .286/.309/.506 line over 22 contests. They’ve been the National League’s most productive catching tandem. Ballesteros can occasionally spell Michael Busch at first base, but his clearest path to at-bats would come as a designated hitter. Seiya Suzuki has drawn into left field while Happ has been day-to-day. Suzuki should play left regularly for the extent of Happ’s IL stint.

Happ has been out to a typically productive start at the top of Craig Counsell’s batting order. He owns a .269/.364/.381 line through 187 plate appearances. His power numbers are a bit lighter than usual, but the on-base mark would be the best of his career. He’d been amidst an 0-14 skid leading up the injury but had collected hits in seven straight games before that. His IL stint can be backdated to May 10, meaning he’ll be eligible to return next week.

It remains to be seen if Ballesteros will stick with the big league club once Happ is healthy. He’s past the point where he can accrue a full year of service time through the traditional means, though he meets the prospect criteria to potentially earn a bonus service year via the Prospect Promotion Incentive. He’d get a full service year if he finishes top two in Rookie of the Year voting. The Cubs would not receive an extra draft choice in that instance because they didn’t promote him early enough in the season. If this is a permanent promotion, Ballesteros would be well-positioned to qualify for early arbitration as a Super Two player during the 2027-28 offseason even if he doesn’t earn the full service year.

Cubs Designate Cody Poteet For Assignment

By Steve Adams | March 27, 2025 at 11:14am CDT

The Cubs announced Thursday that they’ve designated right-hander Cody Poteet for assignment. His spot on the roster will go to righty Brad Keller, who has now formally been selected to the roster. The Cubs also placed righties Tyson Miller (left hip impingement), righty Ryan Brasier (groin strain) and infielder/outfielder Vidal Brujan (elbow sprain) on the injured list and recalled righty Eli Morgan from Triple-A Iowa.

Poteet, 30, was the lone player the Cubs received in the trade sending Cody Bellinger to the Yankees. That swap was always more about dumping Bellinger’s salary than adding to the system, and today’s DFA only further underscores that reality.

A fourth-rounder by the Marlins in 2015, Poteet has pitched in parts of three big league seasons between Miami and New York. He posted a 2.22 ERA in 24 1/3 frames for the Yanks last year and carries an overall 3.80 mark in 83 MLB innings. He was sharp in 53 minor league innings last year as well, recording a 3.40 ERA. Poteet isn’t a flamethrower, sitting 93.8 mph with his four-seamer and 92.6 mph with his sinker. He complements those fastballs with a slider, curveball and changeup, rounding out a five-pitch arsenal.

Poteet has punched out 20.2% of his big league opponents against a 10.2% walk rate. Both are worse than average, though not necessarily by wide margins. In parts of five Triple-A campaigns, he’s logged a 4.47 ERA with a 21.7% strikeout rate and 8.1% walk rate. Poteet still has a pair of minor league options remaining, so if a team acquires him in a trade or claims him off waivers, he can be optioned directly to Triple-A. That could make him an appealing target for clubs seeking affordable rotation depth.

The Cubs owed Bellinger $52.5MM over the next two seasons, though he can opt out of the contract this year and trim $20MM off that guarantee if he feels there are greener pastures in free agency. Chicago paid $5MM of that sum to help facilitate the swap but saved $47.5MM overall. Bellinger was seen as a poor fit on the roster, with Ian Happ, Pete Crow-Armstrong, Kyle Tucker and Seiya Suzuki in the outfield mix and Michael Busch at first base. Time will tell whether the club is better off for it, but for the moment the only thing they have to show for the trade is salary relief and about $25MM of breathing room between the current payroll and the luxury tax threshold.

The Cubs’ Bullpen Outlook

By Steve Adams | March 7, 2025 at 11:11am CDT

The Cubs entered spring training this year with their bullpen largely set. Offseason trade acquisitions of Ryan Pressly and Ryan Brasier added a pair of veteran righties — including a closer, Pressly — to the late-inning mix. Chicago signed lefty Caleb Thielbar to a one-year, $2.75MM deal. That trio joined Porter Hodge, Tyson Miller and Keegan Thompson as virtual locks. All three holdovers pitched very well in 2024, and the latter two are out of minor league options.

There are plenty of candidates for the remaining spots, the bulk of whom are on the 40-man roster already. Righty Julian Merryweather is coming off a poor showing in an injury-marred season that included an April rib fracture and season-ending knee surgery in September. He yielded 11 runs in 15 innings (6.60 ERA), but Merryweather was excellent in 2023, logging a 3.38 ERA and 32.3% strikeout rate in 72 innings for the Cubs. He’s also out of minor league options, which surely gives him a leg up on others. (Four scoreless spring innings with a 5-to-1 K/BB ratio so far isn’t hurting his cause, either.)

Others on the 40-man roster include righties Nate Pearson, Eli Morgan, Jack Neely, Daniel Palencia, Ethan Roberts and Gavin Hollowell. All have at least one minor league option remaining. However, the Cubs have at least one non-roster invitee who’s making a push for a spot: veteran righty Brad Keller.

Maddie Lee of the Chicago Sun-Times wrote yesterday that Keller’s average fastball is up more than three miles per hour this spring, sitting 96.3 mph and topping out at 98 mph. Pitching coach Tommy Hottovy and manager Craig Counsell both spoke highly of Keller’s stuff this spring, with the skipper noting to Lee that Keller has been “more than we expected” so far in camp. Keller’s four runs in seven innings of work don’t stand out, but teams are far more focused on raw stuff, velocity and command when looking at such a small sample. Keller has allowed only seven hits and a walk while punching out six hitters and inducing grounders at a 48% clip so far.

Patrick Mooney of The Athletic reports that Keller’s velocity jump and smoother mechanics have not only made him a legitimate consideration to break camp but made it “likely” that the team will add Keller to the roster. The veteran righty has a looming opt-out opportunity in his deal, so the Cubs will either have to select his contract to the big league roster or risk him landing with another team. His minor league pact comes with a $1.5MM base salary, per Mooney, making Keller an affordable addition to the relief corps if the team sees fit.

Adding Keller to the mix, however, comes with complications. Right now, the Cubs have six relievers who cannot be optioned to the minors in the running for bullpen spots: Pressly, Brasier, Thielbar, Miller, Thompson and Merryweather. Hodge has a full slate of minor league options remaining, but coming off a 1.88 ERA and 31.7% strikeout rate in 43 rookie innings, he’s not going anywhere. He’s locked into a seventh spot in the ’pen.

Effectively, unless the Cubs are willing to move on from Merryweather, they only have one bullpen spot available. Plugging Keller into that spot would render their bullpen largely static, barring injury. Keller has more than five years of MLB service (6.062, to be more specific). He can’t be optioned without his consent.

That level of bullpen inflexibility is tough for any team to manage. Early off-days in the season would help, but if the Cubs needed to call up a fresh arm at any point, they’d be left choosing between optioning Hodge or designating someone for assignment. It’s not an ideal setup.  (The Mets faced a similar situation with their bench when weighing whether to re-sign Jose Iglesias, which is largely why he ended up with the Padres.)

The situation would only grow murkier when righty Javier Assad is healed up from an oblique injury. Assad has been ruled out for Opening Day and is presumably IL-bound to begin the year. If he returns in April, however, he’d likely push righty Colin Rea from the fifth starter’s spot to a long relief role. Rea, like many of his teammates on the staff, can’t be optioned. The Cubs could technically option Assad, but he pitched 147 innings of 3.73 ERA ball out of the rotation last year; his strikeout, walk an home run rates all point to some regression, but Assad has still pitched well enough to this point in his career (3.40 ERA in 294 innings) that he can be considered a lock when healthy.

It’s always possible that further injuries sort the situation out organically. Injuries, particularly on the pitching side of things, are an inevitability for any team over the course of a six-week spring training and 162-game season. But with the bulk of the pitching staff healthy right now and minimal flexibility due to their lack of optionable arms, the Cubs seem like they’ll be forced into some decisions on those out-of-options arms sooner than later.

Hoyer: Cubs Prioritizing “2025 And Beyond” At Deadline

By Anthony Franco | July 22, 2024 at 11:59pm CDT

This morning, The Athletic reported that the Cubs did not anticipate buying at the deadline. President of baseball operations Jed Hoyer essentially confirmed as much in a chat with reporters just before tonight’s matchup with the Brewers.

Hoyer said the front office will approach the deadline with an eye toward to the future. “Where we are right now, I would have to say that moves only for 2024 – unless things change over the next week – we probably won’t do a lot of moves that only help us for this year,” Chicago’s baseball ops leader said (link via Jesse Rogers of ESPN). “If moves help us for 2025 and beyond I think we’re exceptionally well positioned.”

While Hoyer left open the slight caveat that the situation could change this week, there’s not much ambiguity in how he expects to handle the deadline. He spoke frankly about the team’s “poor position” with regards to this season. “We simply dug a hole with underperformance for two months. That doesn’t affect how I view the organization or how I view things going forward but it certainly affects 2024,” Hoyer said.

It’s clear the Cubs aren’t going to pursue any impending free agents. Hoyer didn’t term Chicago’s approach as buying or selling. That leaves open the possibility of trying to acquire MLB talent that is under team control beyond this season. While that’s not unprecedented (the Reds’ acquisition of Trevor Bauer and the Mets’ deal for Marcus Stroman in 2019 are examples of teams acquiring controllable players at the deadline despite being out of contention), it’s not common. The Cubs would need to outbid teams that are motivated to land those players for both a potential playoff push this summer and future seasons.

Chicago’s farm system is regarded as one of the strongest in the league. That gives Hoyer and his staff the ammunition to make a deal for a controllable player of note, but the likelier outcome is that the Cubs will just move a few short-term veterans. Hoyer shot down any suggestion of a complete teardown, saying it’s “not going to be an option so (there’s) no point in going through the hypothetical.” That makes it unlikely they’d deal core pieces who are under contract or team control beyond this season (e.g. Justin Steele, Shota Imanaga, Ian Happ, Michael Busch).

Prioritizing 2025 would ordinarily put a team’s rentals on the table, but the Cubs don’t have much to offer in that regard. Kyle Hendricks, Drew Smyly (whose deal contains a $2.5MM buyout on a $10MM mutual option) and recent minor league signee Jorge López are the only true rentals. Hendricks is playing on a $16.5MM salary and has an earned run average pushing 7.00. While he has pitched better lately after a dismal start to the season, there’d be minimal interest. The Cubs could try to pay down almost all of the contract to find a trade partner. Hendricks also has full no-trade rights after reaching 10 years of MLB service (at least the last five of which have been with his current team) earlier this season.

Smyly has a 2.92 ERA across 37 innings in a long relief capacity. That solid run prevention isn’t supported by mediocre strikeout and walk rates (21% and 10.2%, respectively). Between his $8.5MM salary and the aforementioned option buyout, there’s likely to be limited interest in the veteran left-hander.

Cody Bellinger has the ability to opt out of the final two years and $50MM on his contract. He has had a fine but unexceptional season, hitting .269/.331/.410 across 344 plate appearances. That’d be a difficult contract to move even if Bellinger were healthy, and he went on the injured list a couple weeks ago with a broken finger.

If the Cubs wanted to more or less run things back in 2025, they’d be in for a very quiet deadline. Yet even if they’re not likely to move long-term core pieces, Chicago could entertain offers on role players who are controllable beyond this season. USA Today’s Bob Nightengale reported over the weekend that the Yankees and Red Sox were looking at starter Jameson Taillon, who’ll make $18MM annually between 2025-26. Rogers reports that the Cubs have also gotten interest in third baseman/DH Christopher Morel and relievers Héctor Neris, Mark Leiter Jr. and Tyson Miller.

Morel, 25, is under team control through 2028. He’ll be a borderline candidate for the Super Two cutoff for early arbitration next offseason. The Cubs are certainly under no financial pressure to move him, but it’s possible they’re prepared to move on if another team views Morel as a regular. Morel is a good athlete with big power upside who has never found a defensive home. Chicago has unsuccessfully tried him in second base and throughout the outfield in previous seasons. They’ve given him 562 innings at third base this year, hoping his top-of-the-scale arm strength would work at the position. Defensive Runs Saved and Statcast’s Outs Above Average have each given him very poor grades for his stint at the hot corner.

This also hasn’t been a great season for Morel at the plate. While he has 18 homers, he’s hitting .202 with a .304 on-base mark. It’s a step down from the .241/.311/.471 career slash line that Morel carried into the season. While that’s clearly not ideal, it belies some intriguing developments from a process perspective. Morel has upped his walk rate by a couple points while dramatically slicing his strikeouts. After fanning in over 30% of his plate appearances for his first two seasons, he’s striking out 23.8% of the time this year. An unsustainably low .221 average on balls in play has kept that from materializing into better results.

Even if the Cubs expect Morel’s offensive performance to normalize with an uptick in his average on balls in play, the lack of a defensive fit makes him a difficult player to value. The Cubs could hope to turn third base over to last year’s first-round pick Matt Shaw as soon as next season. They don’t have much in the way of short-term alternatives. If the Cubs traded Morel, they’d probably rely on Miles Mastrobuoni and Patrick Wisdom to cover the position for the rest of the season.

The Cubs should be open to offers on anyone in their bullpen. Neris has handled the ninth inning since Adbert Alzolay went down with a forearm strain. The offseason signee has been shaky, walking 16.1% of opponents and blowing four saves in 17 attempts. Neris had a 1.71 ERA for the Astros last season, but that’s up two runs this year thanks to his control woes. The 35-year-old righty is playing on a $9MM salary and has a matching option for next year. That’s currently a team option but would convert to a player option if Neris pitches in 24 more games.

Given his inconsistency, the Cubs aren’t likely to want Neris back at that price point. They’d presumably be happy to find a trade partner, but the potential for being saddled with a $9MM player option if Neris hits his vesting marker could make other teams wary. There’s less risk with regards to Leiter and Miller. The former is striking out 34.4% of opponents with a 50.6% grounder rate across 34 innings. He’s playing on a $1.5MM salary and is under arbitration control through 2026. Miller, whom the Cubs acquired from Seattle in May, has broken out with a 2.04 ERA while striking out nearly 26% of opponents across 35 1/3 frames.

Whether the Cubs get compelling enough offers to move anyone from that group remains to be seen. They’re not entirely buried in the Wild Card standings, sitting 3.5 games back of the last playoff spot (currently held by the Mets). With four intervening teams to jump, the front office has decided they’re at best a long shot to make the postseason. How much they’re willing to reshape the roster with the ’25 campaign in mind will be one of the bigger questions of the upcoming week.

Cubs To Acquire Tyson Miller

By Anthony Franco | May 13, 2024 at 11:06pm CDT

The Cubs are acquiring reliever Tyson Miller from the Mariners for minor league infielder Jake Slaughter, reports Jeff Passan of ESPN (X link). Seattle had designated Miller for assignment last week.

Miller returns to the organization that selected him in the fourth round of the 2016 draft. The Cal Baptist product reached the majors for a very brief stint during the 2020 season. The Cubs lost him on waivers to the Rangers the following year. That kicked off a nomadic stretch of his career that has seen Miller suit up for five teams without reaching even 15 innings for any of them.

The right-hander played for three teams last year. He bounced via waivers between the Brewers, Mets and Dodgers. Miller combined for 15 1/3 innings of eight-run ball and cleared waivers in September. He hit minor league free agency and inked a non-roster deal with Seattle going into 2024. The M’s called him up two weeks into the regular season.

Miller had a productive month in the Pacific Northwest. He threw 11 2/3 frames over nine appearances, allowing four earned runs. Miller punched out 12 against one walk with a solid 12.6% swinging strike percentage. It was a little surprising that Seattle nevertheless took him off the roster, although he’d been in a low-leverage role in a solid bullpen.

The Cubs have a shakier relief corps than the Mariners do. Chicago’s bullpen entered play Monday ranked 24th in the majors with a 4.58 earned run average. Their 23.4% strikeout rate is fine, but they’ve issued walks at a huge 11% clip. Chicago also has five relievers on the injured list at present. Yency Almonte landed on the shelf over the weekend, while Adbert Alzolay just went down with a forearm strain this evening.

Miller is out of options, so he’ll step right into the major league bullpen. The Cubs need to create a 40-man roster spot to finalize his acquisition and will need to make an active roster move once he reports to the team.

In return for a middle reliever who had been squeezed off the depth chart, Seattle adds an upper minors infielder who is out to a strong start. Slaughter, 27, has a .297/.392/.486 slash line over 130 plate appearances for Chicago’s top affiliate in Iowa. He has connected on five homers, stolen 10 bases in 11 tries, and drawn walks at a strong 11.5% clip. His 24.6% strikeout rate is slightly higher than average but around three percentage points lower than last year’s 27.5% mark.

Slaughter was an 18th-round pick out of LSU back in 2018. He has never drawn much prospect fanfare and has gone unselected in the Rule 5 draft twice. His numbers this season are strong enough that he has a chance to reach the majors in a reserve capacity this year, though. He would qualify for minor league free agency at the start of next offseason if Seattle doesn’t add him to the 40-man roster before then.

Mariners Designate Tyson Miller For Assignment

By Darragh McDonald | May 10, 2024 at 5:15pm CDT

The Mariners announced that Bryan Woo has been reinstated from the injured list, with fellow righty Tyson Miller designated for assignment in a corresponding move.

Miller, 28, signed a minor league deal with the M’s in the offseason and was selected to the big club early in April. He has since thrown 11 2/3 innings over nine appearances with a 3.09 earned run average. He has a 26.7% strikeout rate and 2.2% walk rate. He’s been helped a bit by a .207 batting average on balls in play but his 3.85 FIP and 2.98 SIERA still suggest he’s been pretty good.

That’s a small sample size but it’s still a bit surprising that he’s been bumped off the roster, especially when the Mariners could have optioned someone like Cody Bolton or Eduard Bazardo. For whatever reason, Miller has been bumped off instead. Since he’s out of options, he had to be removed from the 40-man entirely.

The M’s will now have a week to trade Miller or pass him through waivers. The fact that he’s out of options will tamp down interest somewhat, but his decent numbers will be appealing. His 5.91 ERA in his career isn’t especially impressive but that’s in just 42 2/3 innings scattered over a five-year period. Since the start of 2021, he has a 3.85 ERA in 198 2/3 Triple-A innings, striking out 27.7% of batters faced while giving out walks at a 9.7% rate.

Miller has a previous career outright and will therefore have the right to elect free agency if he were to pass through waivers unclaimed.

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, Tyson Miller Agree To Minor League Contract

By Anthony Franco | November 10, 2023 at 9:04pm CDT

The Mariners have signed reliever Tyson Miller to a minor league contract, according to Matt Eddy of Baseball America. It stands to reason he’ll get an invitation to MLB Spring Training.

Miller, 28, has pitched in parts of three big league campaigns. While he only has 31 career innings, he has gotten to the highest level with five different teams. The righty pitched for three clubs in 2023 alone, logging time with the Brewers, Mets and Dodgers. He allowed eight runs over 15 1/3 major league innings between the trio.

A former fourth-round selection, Miller has allowed nearly seven earned runs per nine in the big leagues. While that’s clearly not ideal, he’s coming off a solid run in Triple-A. Miller worked to a 3.50 ERA through 43 2/3 innings at the top minor league level. He struck out nearly 28% of opponents against an average 8.3% walk percentage.

Miller has exhausted his option years. If he cracks the Seattle roster at any point, he’d need to hold his place on the major league club or be put back on waivers. Despite that, the Triple-A results make him a solid depth addition. The Mariners have one of the game’s best bullpens. They finished fourth in the majors in ERA (3.48) and second in strikeout percentage (26.1%) this year.
