Rays Rumors

Poll: Can Drew Rasmussen Keep Pitching Like An Ace?

By Leo Morgenstern | June 10, 2025 at 2:22pm CDT

Drew Rasmussen has pitched into the fifth inning in every start he’s made in 2025. That might not seem so impressive, but Rasmussen is one of just 28 pitchers to have recorded an out in the fifth in 13 or more starts this year. That’s fewer than one per team. Not to mention, he’s coming off internal brace surgery, the third major elbow procedure of his career. Few major leaguers have ever returned from a third such surgery, let alone returned and thrived as the kind of arm a team can count on for five innings every five days.

Even better for Rasmussen and the Rays, his innings stand out for their quality as much as their quantity. In 12 of his 13 starts, he has thrown at least five frames whilst allowing no more than seven baserunners and four runs. No other pitcher – not Paul Skenes, not Jacob deGrom, not Zack Wheeler – has made as many starts that fit that description. All told, the 29-year-old has a 2.22 ERA, the eighth-lowest among qualified AL starters, right in between preseason Cy Young favorites Tarik Skubal and Garrett Crochet. His 0.90 WHIP ranks third, just behind Skubal’s and just ahead of deGrom’s. Underlying those strong results are a 5.3% walk rate, a 50.8% groundball rate, and a 4.8% barrel rate, all of which rank him among the AL’s best. None of his ERA estimators (3.43 SIERA, 3.16 xERA, 3.23 FIP, and 3.31 xFIP) is quite as strong as his low-2.00s ERA, but they’re all still excellent numbers, and only four qualified AL starters have him beat in all four metrics: Skubal, Crochet, Kris Bubic, and Hunter Brown. Those are four of the most exciting young hurlers in the league.

Rasmussen has often flown under the radar, but his ace-like performance this year is hardly coming out of nowhere. Since he arrived in Tampa Bay as part of the Willy Adames trade in 2021, he has pitched to a 2.62 ERA in 347 1/3 innings. He has also compiled 8.2 FanGraphs WAR and 8.8 Baseball Reference WAR in that time. That works out to roughly four wins above replacement per 162 innings, an All-Star-caliber clip. Just as impressive is his consistency. In parts of five seasons with the Rays, he has never had an ERA higher than 2.84. Of course, injuries have severely limited his playing time – he threw 59 innings for Tampa Bay in 2021, 146 in 2022, 44 2/3 in 2023, 28 2/3 in 2024, and he’s thrown 69 so far in 2025 – but his steady excellence is remarkable all the same. Before and after each stint on the IL, Rasmussen has remained dominant. We’re also talking about a guy with the underlying metrics and phenomenal stuff to back up his great results. Since he joined the Rays, only three pitchers have thrown more innings than Rasmussen with a lower SIERA, xERA, FIP, and xFIP: Skubal, Chris Sale, and Spencer Strider. Meanwhile, the comprehensive pitch models at FanGraphs, PitchingBot and Pitching+, both suggest his arsenal has been well above average in every season of his Rays tenure.

So, on the one hand, we’re looking at a pitcher who has excelled at every turn over the past five years. On the other hand, that same pitcher has never thrown more than 146 innings in a season. His second-highest single-season innings total at the MLB level is 76. Both of those campaigns came before his third major elbow surgery. In other words, all of Rasmussen’s stats come from a relatively small sample. Furthermore, we have no way to know for sure that he is capable of pitching a full, qualified season without tiring down the stretch. Most important of all, he’s an injury risk, and he will carry that label for perhaps the rest of his career. So, even in a best-case scenario in which Rasmussen continues to shine and shows no sign of slowing down, the Rays will have to manage his workload carefully. At some point, Kevin Cash might stop him from pitching into the fifth inning every start. It’s not out of the question that Rasmussen could eventually move to the bullpen if the Rays are particularly worried about his innings.

Rasmussen has pitched like an ace so far in 2025. Indeed, on a per-inning basis, he’s been one of the most effective arms in the game since he landed with the Rays in 2021. Yet, it’s far from a guarantee he can keep this up over the next several months. So, what do MLBTR readers think? Has Rasmussen done enough to prove he’s one of the game’s premier starting pitchers? Or will his injury history and lack of experience catch up with him as the season wears on? Have your say in today’s poll:

Rays Promote Ian Seymour

By Mark Polishuk | June 8, 2025 at 7:48am CDT

The Rays have called left-hander Ian Seymour up from Triple-A Durham, with right-hander Cole Sulser optioned to Triple-A in the corresponding move. No 40-man move was required, as Tampa already added Seymour to its 40-man roster last November in advance of the Rule 5 Draft.

The 26-year-old Seymour will be making his Major League debut whenever he makes his first appearance for the Rays. A second-round pick for Tampa Bay in the 2020 draft, Seymour’s pro career hit some immediate roadblocks when flexor soreness and then a Tommy John surgery limited him to just 114 innings over the 2021-23 seasons. If it wasn’t for these health issues, Seymour might well have been in the bigs years ago, as he had already been promoted up to the Triple-A level before the 2021 campaign was over.

Seymour kept the momentum going after his return from TJ rehab. He posted a 2.35 ERA over 145 1/3 combined Double-A and Triple-A innings in 2024, and this season has a 2.95 ERA, 32.7% strikeout rate, and 5.8% walk rate over 61 frames with Durham (starting 11 of 12 games). Baseball America ranks Seymour 15th on their list of the Rays’ top 30 prospects, while MLB Pipeline has him 19th in their ranking of the Tampa Bay farm system.

If these rankings seem a little modest for a starter with Seymour’s numbers, it could be because Seymour’s average fastball velocity only sits in the low-90s. That said, the pitch is still effective, and acts as a nice secondary offering to Seymour’s plus changeup. As Baseball America’s scouting report puts it, Seymour relies on a “combination of command and deception” more than pure stuff, and his results in the minors “will be hard to fully replicate” against big league hitters. Seymour has started 69 of his 71 career games, though evaluators feel he might be more suited to a swingman or bulk pitcher role at the MLB level.

Given their long history of pitcher development and creative usage of their arms, the Rays are ideally suited to manage Seymour’s entry into the Show. Seymour looks to be working as a reliever at first, since Tampa Bay could use a fresh arm after using seven different pitchers in yesterday’s 11-10 extra-innings loss to the Marlins. The steady Drew Rasmussen is starting today but hasn’t gone beyond six innings in any of his 12 starts this season, and the Rays’ next off-day isn’t until Thursday. Seymour joins Garrett Cleavinger and Mason Montgomery as the left-handed options in Tampa’s pen.

Travis Jankowski Elects Free Agency

By Darragh McDonald | June 4, 2025 at 1:40pm CDT

Outfielder Travis Jankowski has cleared waivers and elected free agency, reports Marc Topkin of the Tampa Bay Times. There wasn’t any indication the Rays removed him from their 40-man roster but it appears they quietly put him on waivers recently. This drops their 40-man roster count from 39 to 38.

Jankowski, 34 later this month, was acquired from the White Sox at the end of April. Tampa had a number of outfielders on the injured list and grabbed Jankowski as a veteran fill-in. Unfortunately, Jankowski himself hit the IL a couple of weeks later, landing there on May 15th due to a left groin strain. He started a rehab assignment a few days ago but it seems the Rays didn’t want to put him back on the roster, so they put him on waivers instead.

That’s likely due to their outfield getting healthier in recent weeks. Josh Lowe and Jake Mangum were both on the IL at the time Jankowski was acquired but each of them is now back on the active roster. Those two have slotted next to Kameron Misner in the club’s regular outfield mix with Christopher Morel also factoring in. The Rays considered that group strong enough that they optioned Chandler Simpson last week and don’t have room for Jankowski either.

Unlike Simpson, Jankowski is a veteran with over eight years of big league service time. That means he can’t be optioned to the minors without his consent. It also means he has the right to reject an outright assignment and elect free agency. Those factors have led him to the open market today.

He will now look for his next opportunity, presumably with a club that has a better path to playing time in its outfield. Jankowski has been a strong defender throughout his career. In 3,597 innings on the grass, he has accrued 29 Defensive Runs Saved and 33 Outs Above Average. He can also rack up double-digit steals if given regular playing time in a season.

The offense has been more mercurial. He was around league average with the Rangers in 2023, helping that club surge to a World Series championship. However, he was below average before that and has dropped down again since. On the whole, he has a career batting line of .236/.318/.305. That translates to a wRC+ of 76, indicating he’s been 24% below league average for his career. Since he cleared waivers, he’ll probably have to settle for a minor league deal.

Shane McClanahan Targeting Return Around Late July

By Anthony Franco | June 3, 2025 at 8:44pm CDT

The Rays have a timeline for the return of their ace. President of baseball operations Erik Neander told MLB Network Radio on SiriusXM this week that Shane McClanahan is scheduled to throw a bullpen session on Friday. Neander added that if things go as planned, McClanahan could begin a minor league rehab assignment by the end of the month and return to the big league club in “late July or early August, fingers crossed.”

McClanahan hasn’t pitched in a regular season game since 2023. He was amidst a second straight All-Star season and carried a 3.29 ERA over 115 innings. That’s when he came off the mound in early August with forearm tightness. McClanahan was headed for Tommy John surgery two weeks later. The late-season timing of the injury meant he was almost immediately ruled out for the entire ’24 campaign as well.

Tampa Bay was hopeful of getting McClanahan back at the beginning of this year. He looked sharp over three starts in Spring Training. That was halted when he suffered a nerve injury in his triceps midway through camp. His timeline had been uncertain until now. The Rays will hope for a smooth progression from here that’d allow McClanahan to make it back within the next couple months.

The target coincidentally aligns with the July 31 trade deadline. The Rays almost certainly aren’t going to move McClanahan, but his return could make the front office more comfortable dealing a different starter. Impending free agent Zack Littell is the most obvious trade candidate, but the Rays are generally open to listening to offers on anyone. They’ll presumably get calls on each of Ryan Pepiot, Drew Rasmussen, Taj Bradley and Shane Baz as well.

In other Rays injury news, Marc Topkin of The Tampa Bay Times writes that outfielder Jonny DeLuca will be shut down from all baseball activities for another three weeks. DeLuca has been out since early April with a shoulder strain. He suffered a setback last week and is evidently going to miss quite some time.

Ben Rortvedt Accepts Outright Assignment With Rays

By Darragh McDonald | June 2, 2025 at 10:54am CDT

Catcher Ben Rortvedt, who was designated for assignment by the Rays last week, has cleared waivers and been sent outright to Triple-A Durham. He had the right to elect free agency but has chosen to accept. Marc Topkin of the Tampa Bay Times was among those to relay the information.

Players with at least three years of big league service time have the right to reject an outright assignment and elect free agency. However, exercising that right means forfeiting any remaining salary commitments, unless a player has at least five years of service time.

Rortvedt is between three and four years. He qualified for arbitration for the first time after last season. He and the Rays avoided arbitration by agreeing to a $1.125MM salary for 2025. Rortvedt has pocketed about a third of that already but would have to walk away from the rest of it in order to head to the open market, so it’s not surprising that he has chosen to report to Durham.

For the Rays, they get to keep a bit of experienced non-roster depth behind the plate. Rortvedt had a solid season for them in 2024, getting into 112 games and stepping to the plate 328 times. His .228/.317/.303 slash line wasn’t tremendous, as his 87 wRC+ indicates he was about 13% below league average at the plate. However, catches are usually about 10% below league-wide par, so Rortvedt’s offense was passable enough.

He also received solid marks for his work behind the plate. Putting the two together, FanGraphs considered him to be worth 1.4 wins above the replacement on the year, with Baseball Reference putting him a bit lower at 0.9 WAR.

The Rays were satisfied enough to give him a raise and bring him back for 2025 but his bat has disappeared. Rortvedt slashed .095/.186/.111 in 70 plate appearances before getting designated for assignment last week. A tiny .122 batting average on balls in play wasn’t helping him out but his batted ball metrics all trended in the wrong direction as well. The Rays signed Danny Jansen in the offseason and then acquired Matt Thaiss last week, pushing Rortvedt down the depth chart. Since Rortvedt is out of options, he got pushed off the 40-man entirely.

Though he’s not having a strong season, he should get some regular playing time for Durham and could perhaps get his offense back on track. If he’s able to do so, he could be the first man up if either Jansen or Thaiss suffers an injury. Logan Driscoll is also on the 40-man roster but he started the year on the minor league injured list due to an ankle injury and still hasn’t played an official game this year.

If Rortvedt isn’t called up by the end of the season, he will be able to elect free agency, as is the case with all players with three-plus years of service who are outrighted off a 40-man roster during the season.

Rays Option Chandler Simpson

By Anthony Franco | May 30, 2025 at 11:33am CDT

The Rays optioned top prospect Chandler Simpson to Triple-A Durham this afternoon. That opens a spot on the active roster for Jake Mangum, who was reinstated from the 10-day injured list. Mangum is back after a five-week absence due to a left groin strain.

Simpson heads back down after a six-week run on the big league roster. The Rays selected his contract in the middle of April. The lefty-hitting outfielder appeared in 35 games, hitting .285/.315/.317 through his first 133 plate appearances. There was no power production and a low walk rate, but he kept his strikeout rate below 11% to post a strong batting average.

As expected, he was a menace on the bases. Simpson stole 19 bags in 22 attempts, already launching him to third in MLB (behind Luis Robert Jr. and Bobby Witt Jr.). Those players have been in the big leagues all season, of course. No other player has stolen more than 15 bases since Simpson’s call-up on April 18.

It’s the same profile that the Georgia Tech product has shown throughout his minor league career. Simpson is an elite contact hitter and among the fastest players in the sport. He’s an otherworldly baserunner who successively swiped 94 and 104 bases during his first two full minor league seasons. His 198 combined steals led all minor league players by 68 over that stretch.

The question is how much value Simpson can wring out of that approach when he has zero power. He’s hit one professional home run, an inside-the-parker at Double-A last season. He only collected four extra-base hits in his first MLB look, all of which were doubles. He’s last among MLB hitters (minimum 100 plate appearances) in hard contact rate. A lot could come down to how well he develops defensively. Scouting reports haven’t been enamored with his reads and routes. His speed certainly gives him the potential to be a rangy defender, but he did not grade well over his first 284 MLB innings between center and left field.

Tampa Bay has used Kameron Misner in center with Simpson in left for the past two weeks. Mangum, who was hitting .338/.384/.397 in 21 games before his injury, figures to take over as the starting left fielder. Jonny DeLuca was expected to feature prominently this year as well, but he’s been out since late March with a right shoulder strain. DeLuca revealed this week that he suffered a setback as he continues to feel pain in his rotator cuff, primarily on throws (link via Marc Topkin of The Tampa Bay Times). There’s no suggestion of surgery but he was pulled off the rehab assignment that he’d begun over the weekend.

Rays Sign Kyle Gibson To Minor League Deal

By Darragh McDonald | May 28, 2025 at 4:25pm CDT

4:25pm: The Rays announced that they have signed Gibson to a minor league contract.

3:20pm: Right-hander Kyle Gibson is signing with the Rays, reports Jon Heyman of The New York Post. It’s unclear if it’s a major or minor league deal. If it’s a big league deal, the Rays have an open 40-man spot after designating catcher Ben Rortvedt for assignment earlier today, so they would only need to make a corresponding active roster move.

Gibson, 37, is a veteran with a solid track record but he is having a rough season so far. He lingered in free agency for a long time, eventually signing a one-year, $5.25MM deal with the Orioles less than a week before Opening Day. Since he missed spring training, he agreed to be optioned to the minors to get built up. He was called up at the end of April but got pounded, allowing 23 earned runs in 12 1/3 innings over four starts. The O’s then designated him for assignment and released him.

That leaves Baltimore on the hook for the remainder of that salary, meaning any club can sign Gibson and only pay him the prorated portion of the league minimum salary, with that amount subtracted from what the O’s pay.

It seems the Rays are willing to overlook Gibson’s 16.78 ERA in 2025 to focus more on his career track record. He has 1,878 big league innings under his belt with a 4.60 ERA on the whole. As recently as last year, he was a solid innings eater at the back-end of a rotation. He made 30 starts for the Cardinals in 2024, logging 169 2/3 frames with a 4.24 ERA, 20.9% strikeout rate, 9.4% walk rate and 44.8% ground ball rate.

The Tampa rotation has been without Shane McClanahan all year but has otherwise been remarkably healthy. Apart from one Joe Boyle spot start, every other game has been started by the quintet of Taj Bradley, Ryan Pepiot, Drew Rasmussen, Zack Littell and Shane Baz. No one in that group has an ERA higher than 4.94 this year. The Rays also have guys like Boyle, Joe Rock and Ian Seymour on the 40-man roster and pitching in Triple-A.

Regardless, there’s no real harm to adding Gibson since the O’s are responsible for most of his salary. The Rays could be adding a bit of non-roster rotation depth or perhaps they want Gibson to jump into their big league bullpen and serve as a long reliever. It’s also possible that one of their big league starters has some sort of ailment that has not yet been publicly reported. Time will tell what the Rays have in mind for Gibson’s usage but he’s a respected veteran with a solid track record and essentially no cost.

Rays Designate Ben Rortvedt For Assignment

By Anthony Franco | May 28, 2025 at 8:50am CDT

May 28: The Rays announced this morning that Rortvedt has indeed been designated for assignment. Thaiss has been added to the active roster and will presumably be with his new team for this afternoon’s series finale versus Minnesota.

May 27: The Rays intend to designate catcher Ben Rortvedt for assignment, reports Marc Topkin of The Tampa Bay Times. That will clear an active roster spot for new backup catcher Matt Thaiss, who was acquired from the White Sox this afternoon. Topkin notes that Rortvedt was bidding emotional farewells to his teammates after tonight’s loss to Minnesota.

Rortvedt is out of options. The Rays cannot send him down without putting him on waivers. They’re not going to carry three catchers or move on from starter Danny Jansen, so the Thaiss pickup made a Rortvedt DFA more or less inevitable. The lefty-hitting Rortvedt went 0-3 with a strikeout tonight and is down to an .095/.186/.111 slash line through 70 plate appearances. His strikeout and walk numbers are solid enough, but he has only managed one extra-base hit while ranking near the bottom of the league in hard contact rate.

Tampa Bay acquired Rortvedt from the Yankees in a three-team deal on the eve of Opening Day 2024. He started a little more than half the team’s games last season, batting .228/.317/.303 across a career-high 328 plate appearances. The Rays signed Jansen to an $8.5MM free agent deal to supplant Rortvedt as the primary catcher. The drop in his already poor offense has now squeezed him off the roster. While Thaiss has very little power himself, he’s at least getting on base at a huge .382 clip over 35 games this year.

A former second-pick of the Twins, Rortvedt is a capable defensive catcher. He has graded as a slightly above-average framer and blocker in his career. He has solid arm strength and has thrown out six of 27 attempted base-stealers. Once the Rays officially announce the DFA, they’ll have five days to explore trade scenarios. They’d place him on waivers if they don’t find a trade partner. An acquiring team would need to plug him directly onto the MLB roster.

Rays Acquire Matt Thaiss

By Darragh McDonald | May 27, 2025 at 2:50pm CDT

The White Sox have traded catcher Matt Thaiss to the Rays for minor league outfielder Dru Baker, according to announcements from both clubs. Since Baker wasn’t on the 40-man, the Rays transferred outfielder Jonny DeLuca to the 60-day injured list in order to open a spot for Thaiss. They will need to open an active roster spot once Thaiss reports to the club. Chicago’s 40-man count drops to 39. In terms of their active roster, catcher Korey Lee has been reinstated from the IL to take the vacated spot.

Thaiss, 30, was just acquired by the Sox in the offseason. They sent cash to the Cubs, bringing Thaiss to the South Side. He has appeared in 35 games and stepped to the plate 110 times, with some positive results. He has just one home run but has walked more than he has been struck out, drawing a free pass in 20.9% of his appearances compared to a 19.1% strikeout rate.

That’s better than his previous work on offense. With the Angels in 2023 and 2024, he made 493 trips to the plate. He had a strong 13% walk rate over those seasons but also struck out at a high clip of 28.6%. He was flipped to the Cubs and then the White Sox in offseason trades.

His work behind the plate has been more of a question mark, as he has never received excellent marks back there. Baseball Prospectus and Statcast have considered his blocking and throwing to be adequate but with subpar framing. FanGraphs agrees that Thaiss hasn’t been a great framer in his career but has him above average so far in 2025.

Though his work for the Sox has been adequate on the whole, he never seemed likely to spend a long time on the roster. Thaiss started the year sharing the catching time with Lee, but the Sox had two top prospects waiting in the wings: Edgar Quero and Kyle Teel.

Lee went to the IL fairly early in the season, landing there due to a left ankle sprain on April 10th. That got Omar Narváez to the big leagues briefly but Quero was up in the majors a week later. Now that Lee is healthy again, he and Quero will share the catching work. Teel is playing great in Triple-A and could be up in the majors soon as well. Those factors have all pushed the out-of-options Thaiss off the roster.

For the Rays, they’ve been deploying a tandem of Danny Jansen and Ben Rortvedt behind the plate this year. Jansen started slow but has been heating up lately, getting his line to .200/.333/.336 for the year, which leads to a 103 wRC+. Rortvedt, on the other hand, has a dreary .100/.194/.117 line. That’s only 67 plate appearances but he now has a .187/.277/.266 line and 61 wRC+ over 572 plate appearances in his big league career.

Rortvedt is out of options, so it’s possible he’ll be designated for assignment once Thaiss is able to join the team. If the switch works, the Rays could keep Thaiss beyond 2025. He came into this year with his service clock at three years and 38 days, meaning this is his first of three arbitration seasons. With Jansen on a one-year deal, Thaiss has a chance to stick with the Rays for 2026 if he holds his spot through the end of this season.

In order to make that potential upgrade behind the plate, they are parting with Baker. Now 25 years old, he was selected by the Rays in the fourth round of the 2021 draft. He is considered a capable outfielder but his bat has stalled out at the upper minor league levels. Since getting promoted to Double-A in August of 2023, he has a .280/.345/.338 batting line and 101 wRC+. That includes a .245/.344/.302 line at the Triple-A level.

Even if he doesn’t hit much, Baker at least has wheels. He stole 49 bags in 2023 and 42 last year. For the Sox, they were probably going to cut Thaiss soon anyway, so they have traded him in for a flier on Baker. Baker could perhaps serve as a speedy bench outfielder, with any offensive developments on top of that being a bonus.

As for DeLuca, he suffered a shoulder strain in early April. His 60-day count is retroactive to his initial IL placement, so he will be eligible for reinstatement on June 6th. He just started a rehab assignment on the weekend, so he could perhaps be ready to return to the big leagues once that date rolls around.

AL East Notes: Kim, Rays, Orioles, Red Sox, Dalbec

By Mark Polishuk | May 26, 2025 at 11:26pm CDT

Ha-Seong Kim began a rehab assignment with Triple-A Durham today, marking both his first official on-field appearance with the Rays organization and the first minor league game of his four-plus years in North American baseball, as Kim never saw any time in the minors when he was a member of the Padres from 2021-24. Kim underwent shoulder surgery last October, which chilled his free agent market and allowed Tampa to swoop in for a two-year, $29MM guarantee that allows the infielder to opt out after the 2025 campaign.

Marc Topkin of the Tampa Bay Times writes that Kim and four other injured Rays players (Jonny DeLuca, Jake Mangum, Travis Jankowski, Kevin Kelly) are all scheduled to be activated from the IL over the next few weeks, which might make for a bit of a roster crunch as the Rays figure out how to make room for everyone. Some holes will be created when some current players are optioned to the minors, though Topkin figures the Rays will at least check out the trade market to see if any of their surplus players could potentially draw interest from other teams.
