Mariners Claim Seth Martinez
The Mariners announced that right-hander Seth Martinez was claimed off waivers from the Marlins. Righty Jackson Kowar was placed on the 60-day injured list in Seattle’s corresponding roster move.
Miami designated Martinez for assignment earlier this week, and today’s move makes it four different organizations in a little under four months’ time for the 30-year-old reliever. After spending his first four MLB seasons with the Astros, Martinez was designated for assignment in early November and claimed by the Diamondbacks. He then went to the Marlins on another waiver claim on February 20 before being DFA’ed again a week later, and now Martinez finds himself back in the AL West.
Martinez is out of minor league options, which somewhat explains his carousel of an offseason. With teams prizing flexibility within their bullpens, Martinez’s status makes him something of the proverbial 26th man, while also still having enough value that several teams are interested in having him on their rosters.
Over 111 appearances and 137 1/3 innings with Houston, Martinez often worked as a multi-inning reliever, so the Mariners would deploy him in that same capacity if he ends up on the Opening Day roster. Martinez has a career 3.93 ERA, though his strikeout rate fell rather sharply from 23.1% in 2023 to just 16.2% last season. Between that dropoff and other uninspiring Statcast metrics, the Astros felt comfortable in exposing Martinez to DFA waivers, leading to his busy winter of changing teams.
An innings-eating reliever always carries some usefulness, even on a Mariners team with an unusually durable starting rotation. A good Spring Training performance might help Martinez break camp with the team, or he might find himself on the waiver wire yet again before Opening Day.
Kowar underwent a Tommy John surgery almost exactly one year ago, so he was expected to miss some time at the start of the 2025 season as he finishes up his rehab. The 60-day IL placement means that Kowar won’t make his 2025 debut until late May at the earliest.
Diamondbacks Sign Casey Kelly To Minor League Deal
The Diamondbacks have signed right-hander Casey Kelly to a minor league deal, according to the transactions log on Kelly’s MLB.com profile page.
Kelly, 35, was a first-round pick by the Red Sox back in 2008. He quickly rose to minor league stardom, becoming a consensus top-100 prospect in the sport before he was traded to the Padres alongside future All-Star Anthony Rizzo in exchange for Adrian Gonzalez. Kelly made his big league debut with San Diego just a year later, though he struggled to a 6.21 ERA in 29 innings of work across six starts in that first big league cup of coffee. Tommy John surgery in 2013 forced him to stay away from the big league mound for quite some time after that, however, and upon his return in 2015 he was torched to the tune of a 7.94 ERA in 11 1/3 innings of work that brought the Padres chapter of his career to a disappointing end.
Kelly bounced through the Braves, Cubs, and Giants organizations over the next couple of seasons, even getting a brief look in the majors with Atlanta during the 2016 season, but it wasn’t until the 2018 campaign in San Francisco that the right-hander found success in the majors. That success was fairly limited, as Kelly pitched just 23 2/3 frames at the highest level that year, but his 3.04 ERA was the first above-average showing in the majors of his career. It even earned him some attention on the other side of the world, as Kelly went on to depart the Giants organization in favor of joining the Korea Baseball Organization’s LG Twins.
Kelly’s stint in Korea ultimately lasted six seasons, and saw him put together an impressive overseas career. The right-hander pitched to a 3.25 ERA overall in 989 1/3 innings of work for the LG Twins in parts of six seasons from 2019 to 2024. Those first four seasons were particularly impressive, as Kelly made at least 27 starts in each of them with ERAs ranging from 2.54 to 3.32 and solid peripheral numbers to match. Unfortunately, Kelly started to show signs of decline in 2023 that brought about the end of his KBO career in 2024 after he struggled to a 4.51 ERA in 19 starts for the LG Twins that led the club to cut him from the team in July of last year.
After being cut loose in Korea, Kelly made his way back into stateside ball with the Reds on a minor league deal. He managed to get called up to the majors for a brief stint down the stretch last year, his first stint in the majors in more than half a decade. He pitched just 5 1/3 innings for the Reds last year, surrendering three runs on three hits (one homer) and a walk while striking out four. The right-hander was then outrighted to Triple-A Louisville in August and elected minor league free agency back in October. Now, Kelly appears likely to serve as non-roster depth for the Diamondbacks headed into 2025. He’s got plenty of competition on the club’s pitching depth chart, with Jordan Montgomery, Ryne Nelson, and Tommy Henry among the pitchers just on the 40-man roster who could vie for a long relief role with the club this season.
Rockies Reportedly Place Justin Lawrence On Waivers
The Rockies have placed right-hander Justin Lawrence on waivers, according to a report from Jon Heyman of the New York Post. Notably, that does not mean the righty has been designated for assignment, and Lawrence can continue to workout with the Rockies and pitch in spring games while the waiver process runs its course. With that being said, Lawrence’s placement on waivers is irrevocable, meaning the right-hander will land with a new team in the coming days if any rival clubs put in a claim on his services.
Lawrence, 30, has parts of four MLB seasons under his belt since he debuted with the Rockies back in 2021. After struggling badly in a brief cup of coffee with the club during the 2021 campaign, Lawrence posted lackluster results in 2022 despite solid peripherals. While his 5.70 ERA that year was well below-average, a 3.39 FIP, a 3.54 xERA, and a 3.63 SIERA all suggested Lawrence had pitched much better than his surface level production would’ve suggested. He was a victim of a low 63.7% strand rate and an inflated .350 BABIP, but his strong 25.1% strikeout rate combined with a 50.8% groundball rate made clear the bones of a quality MLB reliever were present.
The right-hander then proved to be exactly that sort of quality MLB reliever the very next year, as he enjoyed a breakout season in 2023 at the age of 28. In 75 innings of work, Lawrence posted a 3.72 ERA with a matching 3.76 FIP while picking up 11 saves during a season where he shared the closer role with struggling veteran Pierce Johnson. Lawrence’s ERA that season may not jump off the page, but when factoring in the inflated offensive environment Rockies pitchers face at Coors Field he was actually well above average as demonstrated by his 134 ERA+. Lawrence’s peripherals more or less matched his work in the 2022 campaign, with a 23.9% strikeout rate, an 11% walk rate, and a 48.5% groundball rate. Entering 2024, it seemed as though the right-hander had a solid foundation for MLB success from which he could build off of going forward.
Unfortunately, that’s not how things worked out. Lawrence had the worst season of his career in 2024 as he surrendered a 6.49 ERA in 59 2/3 innings of work while his peripheral numbers regressed nearly across the board. Lawrence saw his walk rate tick up to 11.8% last year, while his strikeout rate plummeted to just 16.1%. Just four pitchers in the majors last year had a lower K-BB% than Lawrence, and in conjunction with the BABIP and strand rate related issues that are common for pitchers calling Coors Field home, it’s hardly a surprise that the right-hander struggled badly with metrics that mostly supported his poor performance including a 5.63 FIP, a 6.25 xERA, and a 4.73 SIERA.
In his first few outings this spring, Lawrence hasn’t looked much better. Spring results always need to be taken with a grain of salt, but the right-hander has looked wild with three walks and two hit batters against two strikeouts across three innings of work. That seems to have been enough for the Rockies, who expressed a desire to deal Lawrence this winter, to pull the plug. In doing so, the club opens up playing time for younger relief arms like Angel Chivilli and Jeff Criswell amid an noncompetitive season and could save the sum of Lawrence’s $975K arbitration salary if he’s plucked off waivers by another organization.
From when Lawrence is officially placed on waivers, rival clubs will have 48 hours to place a claim for his services. If he goes unclaimed, he’ll remain with the Rockies. The righty could be outrighted off the club’s 40-man roster at that point and stashed in the minors as depth, but Colorado would not necessarily have to do so and could just keep him in their big league bullpen going forward as well.
Red Sox, Nick Burdi Agree To Minor League Deal
The Red Sox have reached agreement with reliever Nick Burdi on a minor league contract, reports Chris Henrique of Beyond the Monster. MassLive’s Chris Cotillo writes that the right-hander will go to minor league camp, as he did not receive a non-roster invite to MLB Spring Training.
Burdi, 32, is a former Twins’ second-round draftee and well-regarded bullpen prospect. His career has been beset by myriad injuries. He underwent Tommy John surgery early in his time in the Minnesota farm system. He landed with the Pirates as a Rule 5 pick, where he battled thoracic outlet syndrome. Burdi’s arm continued to bother him the following year, and he underwent another Tommy John procedure after the 2020 campaign.
The Louisville product didn’t return to the mound until 2023. Burdi landed with the Cubs in the Triple-A phase of the Rule 5 draft. Chicago called him up for three appearances, but he quickly went back to the injured list due to a bout of appendicitis. He didn’t return to the majors and the Cubs cut him loose at the end of the season.
Burdi inked a minor league deal with the Yankees last winter. He broke camp but went on the injured list within a few weeks because of a right hip problem. Renewed hip pain sent him back to the IL between May and August. New York outrighted him one month later, sending him back to minor league free agency at the end of the season.
Despite the latest injury-plagued season, Burdi established a career high with 12 MLB appearances for the Yankees. He fired 9 2/3 frames of two-run ball. Burdi fanned 12 with nine walks. It was a similar story in Triple-A, where he turned in a 2.65 earned run average through 17 innings. He struck out a third of opponents against a huge 15.3% walk rate.
The raw stuff remains intriguing. Burdi averaged 97.5 MPH on his fastball while sitting in the upper 80s with his slider. He doesn’t consistently harness that high-octane arsenal, but that could be tied to the stop-and-start nature of so many of his seasons. There’s no real downside for the Red Sox in bringing him to camp and sending him to Triple-A Worcester to open the year.
Dinelson Lamet, Socrates Brito Sign With Mexican League’s Águila De Veracruz
The Águila de Veracruz are signing Dinelson Lamet for the 2025 season, according to a Spanish-language article at MiLB.com. The Águila also announced on social media this week that they’ve added outfielders Sócrates Brito and Nomar Mazara.
Lamet appeared in the majors as recently as last season. He pitched in three games for the eventual World Series champions. Lamet inked a minor league deal with the Dodgers last February. They selected his contract not long after Opening Day. He tossed 4 1/3 innings of two-run ball before being designated for assignment and outrighted. He opted out of his deal with L.A. in June and finished the year on a minor league contract with the Royals.
The fourth-place finisher in NL Cy Young balloting in 2020, Lamet has dropped into a depth role. The 32-year-old righty started 18 of 19 games in Triple-A last season. He allowed nearly five earned runs per nine with a mediocre 19.5% strikeout rate and an alarming 13.5% walk percentage.
Brito, 32, appeared in the majors with the Diamondbacks and Blue Jays between 2015-19. The lefty-hitting outfielder spent the past three seasons in Korea with the Kia Tigers. He’s coming off a .310/.359/.516 showing in a hitter-friendly league. While there was some thought that Brito could return to affiliated ball on a minor league contract, that interest apparently didn’t materialize. Mazara is headed into his second Mexican League season after hitting .307/.390/.496 in 70 games with Monterrey last year.
Marlins Claim Brett de Geus, Desigate Seth Martinez For Assignment
The Marlins announced that they have claimed right-hander Brett de Geus off waivers from the Pirates. The latter club designated him for assignment last week. In a corresponding move, the Marlins designated fellow right-hander Seth Martinez for assignment.
de Geus, 27, has never pitched for the Pirates. They acquired him from the Blue Jays in a cash deal last month. Though when they were able to sign Andrew Heaney last week, de Geus was the roster casualty.
He has bounced around the league quite a bit, pitching for the Mariners, Marlins and Jays last year. His major league work to this point hasn’t been great, as he has a 7.48 earned run average in 61 1/3 innings. His 16.6% strikeout rate and 10% walk rate are both poor marks, but he has generated ground balls on 52.5% of balls in play.
Those grounders are likely why he keeps garnering interest from so many clubs, despite the poor run prevention. He also tossed 39 Triple-A innings last year with a 5.31 ERA, getting grounders at a 56.6% clip.
The raw stuff is also intriguing. de Geus averaged 96.4 miles per hour on his sinker last year and 98 mph on his four-seamer, in addition to throwing a knuckle curve, cutter and splitter. He didn’t translate that arsenal into good results last year but clubs clearly think it’s possible, including the Marlins, as they claimed him off waivers in August. They bumped him off the roster a month later, with de Geus claimed by the Jays, but the Fish have now taken the chance to bring him back into the fold again.
He still has options and therefore won’t need to be guaranteed a roster spot. He also has just a bit more than a year of service time, meaning he can theoretically be affordably controlled for years to come if things click for him.
Martinez, 30, was himself just claimed off waivers a week ago. He is out of options and therefore has less roster flexibility than de Geus. With the quick claim and DFA, it’s possible the Marlins claimed Martinez with the plan to put him right back on waivers in short order. He has less than three years of service time and no previous career outright, so he would stick with the Marlins as non-roster depth if he can be passed through waivers unclaimed.
The righty tossed 137 1/3 innings for the Astros over the past four years with a 3.93 ERA, 20.7% strikeout rate and 9.2% walk rate. Over that same timespan, he also threw 105 innings in the minors with a 2.66 ERA, 31.5% strikeout rate and 10% walk rate. He got put on waivers at the end of last season, getting claimed by the Diamondbacks, though the Snakes put him back on waivers when they signed Kendall Graveman.
The Fish will now have one week of DFA limbo to figure out what’s next for Martinez, whether that’s a trade or another trip to the waiver wire. The waiver process can take as long as 48 hours, so any trade interest would have to be explored in the next five days.
Pirates Sign Andrew Heaney
February 27: Per Ethan Hullihen, Heaney’s bonuses start at $50K for 120 innings pitched, followed by $100K for 130 innings and then $150K for 140, 150, 160 and 170. He can therefore earn an extra $750K if he unlocks all of those. When combined with his $5.25MM guarantee, he can earn as much as $6MM this year.
February 22: The Pirates officially announcing the signing.
February 20: The Pirates are reportedly in agreement with Andrew Heaney on a one-year deal that’ll guarantee $5.25MM. The deal, which is pending a physical, also includes performance bonuses for the Icon Sports Management client. Pittsburgh’s 40-man roster is at capacity, so they’ll need to make a corresponding move when the signing is finalized.
It’s a relatively low-cost addition to the back of the rotation. Heaney has been a capable fourth or fifth starter in Texas over the last two seasons. He turned in a 4.15 ERA across 147 1/3 innings two seasons ago. Last year, he pitched to a 4.28 mark while ranking second on the team with 160 innings. Heaney took the ball 66 times for the Rangers and allowed 4.22 earned runs per nine over 307 1/3 frames.
The 33-year-old southpaw had a solid if unspectacular strikeout and walk profile. Heaney has fanned around 23-24% of opposing hitters in each of the past two seasons. After running a career-high 9.4% walk rate in ’23, he cut the free passes to a personal-low 5.9% clip last year. His 12% swinging strike rate was a little better than average.
Heaney has long had the ability to miss bats. Last season’s 22.9% strikeout rate, while slightly above the 22% league average for starting pitchers, was Heaney’s lowest mark in a decade. He has never really been a flamethrower. Heaney’s fastball sat in the 92-93 MPH range during his best seasons. It was down slightly to 91.5 MPH on average last year. The pitch has always had good life that allows it to play above its velocity as a swing-and-miss offering.
Despite the impressive strikeout rates, Heaney owns a 4.45 ERA in more than 1000 career innings. As a fly-ball pitcher without huge velocity, he’s quite susceptible to home runs. Heaney has allowed 1.54 homers per nine innings in his career, while he surrendered 1.29 longballs per nine last year. The Pirates hope that their park can mitigate some of that. According to Statcast’s park factors, only Oracle Park and the Oakland Coliseum have played less favorably for home runs over the past three seasons than PNC Park. Pittsburgh’s home field has been the toughest venue for right-handed power hitters, in particular, so there aren’t many more sensible landing spots for a fly-ball lefty pitcher.
Pittsburgh has a loaded top three in their rotation: Paul Skenes, Jared Jones and Mitch Keller. Heaney projects as the fourth starter. Bailey Falter, who has a similar profile as a soft-tossing lefty, is the favorite for the fifth spot. The Bucs thinned their rotation depth when they included Luis Ortiz in the return for first baseman Spencer Horwitz. Depth options on the 40-man roster include Braxton Ashcraft, Mike Burrows and Johan Oviedo (the latter of whom will return after missing the ’24 season rehabbing Tommy John surgery). Prospects Bubba Chandler and Tom Harrington have reached Triple-A and should make their debuts at some point in 2025.
This is Pittsburgh’s sixth major league free agent pickup of the offseason. They’ve all been one-year commitments worth fewer than $6MM. They brought back Andrew McCutchen on another $5MM guarantee and added Tommy Pham ($4MM), Caleb Ferguson ($3MM), Adam Frazier ($1.5MM) and Tim Mayza ($1.15MM). Pittsburgh’s player payroll now sits around $88MM, as calculated by RosterResource. That’s essentially where they ended last season. Cot’s Baseball Contracts projects the Pirates for the fifth-lowest payroll in MLB.
Heaney was one of the few remaining free agent starters who was sure to find a big league deal. Jose Quintana and Kyle Gibson are the best unsigned options for teams looking to deepen their rotation.
Robert Murray of FanSided first reported the Pirates and Heaney were nearing a deal. Jon Heyman of The New York Post confirmed the agreement. Alden González of ESPN had it as a one-year deal at $5MM with incentives. Andrew Destin of the Pittsburgh Post-Gazette reported the guarantee was $5.25MM. Image courtesy of Imagn.
Nationals Designate Stone Garrett For Assignment
The Nationals announced Thursday that they’ve designated outfielder Stone Garrett for assignment. His roster spot goes to righty Kyle Finnegan, whose one-year deal to return to the Nationals is now official.
Garrett, 29, has appeared in parts of three big league seasons between the Nats and D-backs. He’s a lifetime .276/.341/.492 hitter in the majors, good for 25% better than average at the plate, by measure of wRC+. However, that production has been buoyed by a hefty .369 average on balls in play that’s not going to be sustained over a larger sample than Garrett’s 361 MLB plate appearances. He’s also fanned in 30.2% of his career plate appearances, leading to further questions about his ability to sustain his level of output.
Garrett also saw only six big league plate appearances in 2024, spending the rest of the season in Triple-A with a disappointing .249/.348/.333 slash. That lack of production is likely attributable — to at least some extent — to left ankle/leg surgery performed in Aug. 2023. Garrett sustained fractures in his fibula and ankle when chasing down a fly-ball and crashing into the wall at Yankee Stadium. He spent eight-plus months recovering from that gruesome injury.
The strikeout issues Garrett has faced have plagued him against righties and lefties alike. However, Garrett has shown considerably more power against southpaws. With a 30.8% strikeout rate and .362 BABIP against lefties, he’s not going to sustain his .279/.333/.541 output against them. That huge .262 ISO against southpaws should be enough to make him a viable platoon candidate, even if his average and OBP are ticketed for decline. The Nats already have a full outfield with James Wood, Jacob Young and Dylan Crews, though, and righty-swinging Alex Call is a similar platoon fourth outfielder with roughly half the strikeout rate and better defensive skills.
While Garrett has some notable red flags, he’s still an optionable corner outfielder with genuine power against lefties. That’s a skill set that could fit him into the bench mix for plenty of clubs. He’s coming off a down year, but teams might take an optimistic outlook now that he’s 18 months removed from that devastating injury. The Nats will have five days to trade Garrett, and if they don’t have a deal in place at that point he’ll be placed on outright waivers and learn whether he’s been claimed or cleared 48 hours later.
Mets Sign Jose Ureña To Minor League Deal
10:52am: Ureña’s deal has a $2MM base salary and another $750K available via incentives, reports Jon Heyman of the New York Post.
8:20am: Veteran right-hander Jose Ureña popped up at Mets camp this morning and tells Newsday’s Tim Healey that he’s signed a minor league deal with the club. He’ll join their big league camp for the remainder of spring training. Ureña is repped by Premier Talent Sports & Entertainment.
The 33-year-old Ureña adds some non-roster depth to a Mets rotation that’s already been hit by a pair of spring injuries. Left-hander Sean Manaea has an oblique strain that’ll likely prompt a season-opening IL stint, though he could return by mid-April. Right-hander Frankie Montas has a more significant injury — a lat strain that’s shut him down from throwing for more than a month. He’s likely looking at a mid-May return in a best-case scenario.
Ureña spent the 2024 season with the Rangers, working primarily out of the bullpen but also making nine starts over the course of the season. He totaled 109 innings with a solid 3.80 earned run average, though not all of his numbers looked quite so sharp.
Ureña’s 15.1% strikeout rate was among the lowest in the league, and his 8.4% walk rate was roughly average. He notched a strong 50.1% ground-ball rate and kept the ball in the yard nicely enough (1.07 HR/9), but metrics like FIP (4.62) and SIERA (4.66) felt like he had a fair bit of good fortune to reach that more impressive ERA mark. Ureña’s .273 average on balls in play was a bit shy of the .289 mark he carried into the season, and his 75% strand rate was also higher than both league average (72%) and his career mark prior to 2024 (69.5%).
On the whole, Ureña has a 4.76 ERA in 948 1/3 big league innings. He had some stretches early in his career where he delivered solid midrotation results for the Marlins but has since been hit hard more often than not as he’s moved into journeyman status. His solid 2024 run in Texas was the first time since 2018 that he’s posted an ERA south of 5.00.
Ureña isn’t going to jump right into the Mets’ pitching plans, but there’s also little harm in seeing if a veteran arm coming of a nice rebound effort can sustain some of his production — especially early on while the rest of the pitching staff is a bit banged up. Even with Montas and Manaea ailing, the Mets have signaled they plan to stick with in-house arms, by and large. Kodai Senga, David Peterson, Clay Holmes, Paul Blackburn, Griffin Canning and Tylor Megill give the Mets six experienced arms on which to rely. Top prospect Brandon Sproat could join the mix midseason.
As such, if Ureña is to make the club, it’d likely be as a swingman — but it’s equally or more likely that he’ll opt back into the market if he doesn’t make the club. As an Article XX(b) free agent (i.e. six-plus years MLB service, finished the prior season on a major league roster/injured list), Ureña will have a trio of uniform opt-out dates on his contract: five days before the season (March 22), May 1 and June 1.
Padres Re-Sign Reiss Knehr To Minor League Deal
Right-hander Reiss Knehr and the Padres have reunited on a minor league deal, as first reported by Mad Friars. It’s unclear if the ACES client will be in big league camp as a non-roster invitee or if he’ll head to minor league camp.
Knehr, 28, missed the 2024 season. He underwent Tommy John surgery in the previous summer. The Padres outrighted him off their 40-man roster at the end of the 2023 season. He spent the entire 2024 campaign on the injured list for Triple-A El Paso, then became a free agent at season’s end.
Prior to that lengthy layoff, he was a depth arm for the Friars. He spent the 2021 through 2023 seasons getting frequently optioned to El Paso and back. Over those three years, he tossed 48 1/3 innings in the majors, allowing 5.96 earned runs per nine. His 15.5% strikeout rate and 13.2% walk rate were both subpar figures. That was mostly relief work, with a few “starts” lasting a few innings, topping out at four frames.
As one would expect, his minor league work was more interesting. In 2021, he tossed 75 2/3 innings on the farm over 16 starts and three relief appearances. He had a 3.57 ERA, 21.5% strikeout rate and 10.1% walk rate. In 2022, he posted a dismal 6.88 ERA in a swing role at the Triple-A level, but got back on track the following year. In 2023, he tossed 36 2/3 innings for El Paso, almost exclusively in relief. His only start lasted just three innings. He had a 3.93 ERA for the Chihuahuas, pairing a 27.3% strikeout rate with a 7.3% walk rate.
With those intriguing Triple-A numbers in 2023 and a lost season in 2024, perhaps the Friars will keep him in a relief role from now on. If he shows some health and effectiveness, he will provide the club with a bit of extra non-roster depth. If his contract is selected, he is now out of options but he has barely a year of service time.
