Chase Dollander Undergoes Internal Brace Surgery
Rockies right-hander Chase Dollander underwent internal brace surgery yesterday, skipper Warren Schaeffer tells Kevin Henry of The Denver Gazette. Schaeffer had said a few weeks ago that Dollander’s UCL sprain was trending toward surgery, and that has proven to be the case.
It’ll not only officially end Dollander’s season but likely cost him the first half of 2027 as well. The internal brace procedure typically comes with a year-long recovery timeline. It’s not quite as bad as the full Tommy John reconstruction but still a significant blow for any pitcher.
That’s particularly true in this case, as the 24-year-old Dollander is arguably the most important player in the organization. The ninth overall pick in the 2023 draft, he has the highest ceiling of any pitcher on the club. Dollander struggled with Coors Field as a rookie. He had seemingly figured things out in year two, working to a 3.89 ERA while striking out a quarter of opponents across 44 innings.
The Rockies used Dollander behind an opener early in the season. They had moved him into a more traditional rotation role shortly before the injury. Dollander had a couple clunkers — most notably a six-run outing against Atlanta on May 2 — but was clearly Colorado’s best starting pitcher. His four-seam fastball and sinker were both in the 98-99 mph range as he got swinging strikes on 12% of his offerings.
Colorado is again the worst team in MLB. They’re playing at a 64-win pace as they try to avoid what would be a fourth consecutive 100-loss campaign. Rockies starters have easily the sport’s highest ERA, allowing 5.88 earned runs per nine. Their 16.2% strikeout rate is also worst in MLB. They’ve fared equally poorly on the road as they have at Coors Field. Dollander was the only Colorado starter who had struck out even 20% of opponents and they’ve all been susceptible to the home run ball.
Kyle Freeland, Tomoyuki Sugano, Michael Lorenzen and injured southpaw Jose Quintana are all likely to hit free agency. Righty Ryan Feltner has a couple remaining seasons of arbitration control and is the only member of Colorado’s current starting five who projects for next year’s Opening Day rotation. It wouldn’t be a surprise if they re-sign Freeland to a cheaper one-year contract as well. In any case, they’ll need to overhaul the group next winter and have an uphill path to building the sustainable pitching pipeline they’ll require to eventually emerge from the rebuild.
Chase Dollander Expected To Undergo UCL Surgery
The Rockies provided a brutal injury update on Friday night. Manager Warren Schaeffer tells Kevin Henry of The Denver Gazette that Chase Dollander is expected to require surgery to repair UCL damage in his elbow. The Rox haven’t finalized those plans yet, as Schaeffer indicated the righty has one more pre-operation appointment in the coming days.
Dollander has been out since the middle of May with an elbow sprain. They transferred him to the 60-day IL this afternoon when they promoted Sean Sullivan. Schaeffer indicated that while the team was initially optimistic that Dollander could avoid surgery, the injury hasn’t healed as they hoped.
It’s about as bad a development as the Rockies could have. Dollander is arguably the most important player in the organization. The ninth overall pick in the 2023 draft, he has the highest ceiling of any pitcher on the club. Dollander struggled with Coors Field as a rookie. He had seemingly figured things out in year two, working to a 3.89 ERA while striking out a quarter of opponents across 44 innings.
The Rockies used Dollander behind an opener early in the season. They had moved him into a more traditional rotation role shortly before the injury. Dollander had a couple clunkers — most notably a six-run outing against Atlanta on May 2 — but was clearly Colorado’s best starting pitcher. His four-seam fastball and sinker were both in the 98-99 mph range as he got swinging strikes on 12% of his offerings.
It was too small a sample to know if Dollander had truly arrived as a top-of-the-rotation arm. He’s the only Colorado pitcher who has anything close to that kind of ceiling. Assuming he undergoes surgery, he’ll be done for the rest of this season and a good portion of next year. An internal brace procedure usually comes with a 12-14 month return timeline. If he requires a full Tommy John reconstruction, there’s a chance he’ll miss the entire ’27 season.
The Rockies are trending toward a fourth straight 100-loss season. They’re very unlikely to be competitive next year either. The development of young players like Dollander is the primary focus for the Colorado fanbase as they remain near the nadir of their rebuild.
Dollander is under club control for the next six seasons, barring changes to the service time structure in the next collective bargaining agreement. He’ll collect an MLB salary and service time while he’s on the injured list. Colorado will need to carry him on the 40-man roster over the offseason but can place him back on the 60-day IL when Spring Training begins next year.
The Rox have arguably the worst rotation in MLB for a second straight year. Kyle Freeland, Tomoyuki Sugano, Michael Lorenzen and Jose Quintana are all going to hit free agency. Ryan Feltner will be back if he’s tendered an arbitration contract. Tanner Gordon, McCade Brown, Gabriel Hughes and Sullivan are also among those on the 40-man roster. They all profile as back-end or organizational depth types. They’ll need to completely overhaul the rotation next winter while trying to acquire any kind of controllable pitching in their deadline approach.
Rockies Promote Sean Sullivan For MLB Debut, Move Chase Dollander To 60-Day IL
5:03pm: The Rockies announced Sullivan’s promotion. To make room, they shifted right-hander Chase Dollander to the 60-day IL and optioned lefty Sammy Peralta to Triple-A. Dollander has been down with an elbow sprain since May 15. He will now stay on the shelf until at least July 15.
12:57pm: The Rockies are set to promote pitching prospect Sean Sullivan, according to Kevin Henry of the Denver Gazette. Sullivan will start tonight against the Athletics and make his major league debut in the process. The lefty is not on Colorado’s 40-man roster, which is currently full. Thus, a corresponding move will be needed in order to select Sullivan’s contract.
Sullivan, 23, was the Rockies’ second-round draft pick in the 2023 draft. He currently ranks as the organization’s No. 11 prospect, according to MLB.com. Sullivan fared well in 20 starts between Single-A and Double-A last year, posting a 2.94 ERA in 104 innings with a 24.9% strikeout rate. He’s been less fortunate in 2026, with a 5.60 ERA in 11 starts at Triple-A.
The 6’4″ Sullivan is a bit of an oddity in terms of his raw stuff. He throws a four-seamer 41.0% of the time, but the pitch only averages 89.0 MPH. Sullivan mixes in an upper-70s slider 29.9% of the time, plus a changeup and cutter at 14-15% each. The changeup is Sullivan’s best pitch, while scouting reports rate his fastball and slider as slightly below-average. Despite the low velocity, Sullivan generally thrives by leveraging pinpoint control and a deceptive, low three-quarters arm slot (video courtesy of MLB.com). He walked just 6.0% of hitters in the minors last year and has walked 7.7% of hitters at Triple-A in 2026.
Sullivan will now have a chance to prove himself in the big leagues as a control and deception guy. Tonight’s game is at Las Vegas Ballpark, the hitter-friendly home of the Athletics’ Triple-A affiliate. If he sticks around for multiple starts, Sullivan could then try his luck at high altitude, with the Rockies hosting the Red Sox at Coors Field from June 22-24.
Rockies starters have performed poorly in 2026, as is seemingly the case every year. The rotation’s 5.94 ERA is dead last in the Majors and 26% worse than average even accounting for the games at Coors. No Rockies starter has thrown enough innings to qualify, with Tomoyuki Sugano just barely missing the cut at 68 1/3 innings. Sugano’s 4.08 ERA is palatable but well shy of his 7.39 xERA, which shows he’s been extremely lucky. Michael Lorenzen and Kyle Freeland are the only others to throw at least 50 innings. Both have ERAs over 7.50.
Given those underwhelming performances and injuries to other starts, there’s little harm in calling up Sullivan. Chase Dollander, one of the team’s more promising arms, has been out with a right elbow sprain for over a month and is not expected to return soon. Tanner Gordon made two starts at the end of May before landing on the 15-day injured list with a right hip impingement retroactive to June 2nd. He’s expected to throw a bullpen soon. FanGraphs’ RosterResource tool currently has the club at a four-man rotation of Lorenzen, Ryan Feltner, Freeland, and Sugano, so Sullivan can serve as the fifth starter until Gordon returns.

Rockies Place Chase Dollander On IL With Elbow Sprain
The Rockies announced a series of roster moves today. Most notably, right-hander Chase Dollander has been placed on the 15-day injured list due to a right elbow sprain. (The Rockies initially said it was a strain but later issued a correction.) Left-hander Sammy Peralta has been recalled to take his spot on the roster. The Rockies also placed infielder/outfielder Tyler Freeman on the paternity list. Outfielder Sterlin Thompson has been recalled for Freeman and will be making his major league debut as soon as he gets into a game.
To this point, not a lot of details have been made public regarding Dollander, but the signs are a bit ominous. Dollander departed yesterday’s start in the second inning, with the team providing a vague diagnosis of arm tightness. Quickly placing him on the IL might not necessarily be any kind of flag, since it makes sense that they would be cautious with their prized young righty. But a sprain, by definition, means there is some degree of tearing or stretching involving a ligament.
Perhaps the team will have more information on his status later. At the very least, they will be proceeding without Dollander in the rotation for the next couple of weeks. Dollander has technically been working as a reliever for the most part this year, but his relief outings have seen him pitch multiple innings behind an opener, effectively a starter’s workload. Four spots in the rotation are taken by Kyle Freeland, Michael Lorenzen, Jose Quintana and Tomoyuki Sugano. They don’t have an off-day until May 28th, so some kind of solution will be needed for the fifth spot.
Tanner Gordon has been pitching three- and four-inning stints out of the bullpen, including four frames following Dollander yesterday, so he is perhaps the simplest guy to slot in. Ryan Feltner is currently on the IL and doesn’t appear close to a return, though he could be a factor down the line. In Triple-A, the Rockies have Gabriel Hughes, Carson Palmquist, Valente Bellozo and Blas Castaño, who are all on the 40-man roster, so one of them could be recalled.
Thompson, 25 next month, was drafted 31st overall in 2022. He has since been climbing the minor league ladder. The Rockies added him to their 40-man roster in November of last year, to keep him out of the Rule 5 draft.
He has a tremendous .344/.491/.496 line in Triple-A this year. That’s surely a bit misleading since he’s been playing in the hitter-friendly Pacific Coast League and also has an unsustainable .419 batting average on balls in play. Still, his 18.6% walk rate is massive and higher than his 17.4% strikeout rate. However, the offensive part of his game has never really been the concern. Some evaluators think he’ll be a below average defender, even in an outfield corner. That means he’ll really have to hit to provide value.
It’s possible this will just be a brief call for Thompson. Stints on the paternity list last for one to three days, so Freeman should be back relatively quickly. The Rockies have Mickey Moniak, Jake McCarthy, Brenton Doyle and Jordan Beck getting playing time in their outfield at the moment. If Thompson doesn’t have a path to regular at-bats, it makes sense for him to go back down when Freeman returns, but he can get a taste of big league life now.

Rockies Notes: Dollander, Herget, Criswell
The Rockies are dealing with an injury concern for their top young pitcher. Chase Dollander left this afternoon’s start in Pittsburgh in the second inning on account of right arm tightness.
Dollander told Thomas Harding of MLB.com postgame that the club had not scheduled any imaging. “I don’t know; I’m not sure,” he replied when asked about his level of concern. “I don’t want to say too much before anything else happens – not to freak myself out or anyone else.”
The ninth overall pick in the 2023 draft, Dollander struggled at Coors Field as a rookie last season. He has taken a major step forward this year, entering today’s outing with a 3.35 ERA across 43 innings. He’d punched out 26% of opponents while averaging 99 mph on his four-seam fastball. Pittsburgh rocked him for five hits and three runs in an inning-plus today, although it’s fair to attribute the ugly start to the arm discomfort.
Dollander tells Harding he first felt some arm discomfort coming out of last Friday’s start in Philadelphia. He had a slight velocity dip this afternoon, sitting 97-98 mph with the heater instead of his usual 99. That’s not much of a concern in itself — it was the first inning and the game temperature was in the high 40s — but becomes more alarming in conjunction with the arm discomfort.
The Rox haven’t revealed whether Dollander will go on the injured list. It’d behoove them to exercise caution with the most important member of their pitching staff. Today’s loss dropped Colorado to an NL-worst 17-27 record. They’re still early in what’ll be a long-term rebuild, so the focus should be on Dollander’s health.
Tanner Gordon helped preserve the bullpen by tossing four innings of one-run ball in mop-up work. Gordon wasn’t even on the active roster until this morning, as Colorado recalled him from Triple-A Albuquerque before the game. That came as the corresponding move for reliever Jimmy Herget, who landed on the 15-day injured list with a shoulder impingement.
A waiver claim after the 2024 season, Herget provided the Rox 83 1/3 innings of 2.48 ERA ball a year ago. He has a less impressive 5.06 mark through 16 frames this year, albeit with similar strikeout and walk rates as he posted last season. Herget has always attacked the strike zone. He doesn’t have huge stuff but is missing a decent number of bats with a heavy dose of breaking balls from a sidearm delivery.
Herget is playing on a $1.55MM arbitration salary and has one year of control after this one. He’s not going to be any contender’s top bullpen target but could draw deadline interest as a deception-based middle reliever if he’s healthy. The Rockies would presumably be happy to move him for a lottery ticket prospect if the opportunity presents itself.
In other injury news, reliever Jeff Criswell was assigned to Albuquerque this week as he continues his rehab assignment. The righty is working back from Tommy John surgery which he underwent in Spring Training 2025. That interrupted a promising start to Criswell’s MLB career. The University of Michigan product struck out 31% of opponents with a 2.75 ERA over his first 19 2/3 innings back in 2024.
Can Chase Dollander Defeat Coors Field?
Rockies right-hander Chase Dollander fired seven scoreless innings to earn a win against the Mets on Sunday. The outing lowered his April ERA to a pristine 1.29. He’s piled up 34 strikeouts over 28 innings this month. Sunday’s outing was the first traditional start of the season for Dollander. He’d pitched exclusively out of the bullpen to begin the year, typically as a bulk reliever following an opener.
Dollander’s win over the Mets came at Citi Field. It was his fifth appearance on the road this season, compared to just two games at Coors Field. The young righty has been able to tame the hitter-friendly venue so far. Dollander allowed a run over 4 1/3 innings at home against the Phillies in his second outing of the season. He limited the Padres to a run across six innings early last week, piling up nine strikeouts. Colorado scored one run total in Dollander’s two home games, saddling him with the loss both times.
The Rockies took Dollander with the ninth overall pick in the 2023 draft. MLB Pipeline ranked him as the No. 2 prospect in the system in 2024, behind only infielder Adael Amador. Dollander struck out minor leaguers at a healthy 33.9% clip that season. The hard-throwing righty debuted with the Rockies last year. The results were brutal in basically every regard. Dollander struggled to miss bats, failed to find the strike zone consistently, and was frequently barreled. His 6.52 ERA was backed by an xFIP and SIERA near 5.00.
Dollander has taken a step forward in multiple areas in his second attempt as a big leaguer. He’s added a tick to his fastball, which was already extremely hard for a starter. Dollander’s four-seamer is sitting at 99 mph this year, ranking fourth among all pitchers. He’s more than doubled his sinker usage, contributing to a well-above-averge 51.9% groundball rate. Despite the increase in sinkers, Dollander has a strong 13.4% swinging-strike rate.
Keeping the ball on the ground while getting ample whiffs is a great recipe for success. Dollander’s 55.7% hard-hit rate stands out as a red flag, but it’s not turning into damage due to the type of batted balls he’s permitting. Only 8.9% of the contact against Dollander has been pulled in the air. Hard-hit balls on the ground and to the opposite way are generally going to lead to better outcomes for a pitcher than pulled air contact.
Colorado brought in Paul DePodesta to run baseball operations this offseason. He’s tasked with reviving a club that hasn’t won 70 games since 2021. The organization is currently in a seven-year playoff drought. DePodesta’s tenure is off to a solid start. The Rockies are just three games under .500 after sweeping the Mets over the weekend. The acquisitions of TJ Rumfield (trade) and Troy Johnston (waiver claim) have been additive, as has the signing of Tomoyuki Sugano. The Johnston addition came shortly before the DePodesta hire was announced, but it’s still part of what looks to have been a productive winter. DePodesta didn’t draft Dollander, of course, but his regime will be in charge of the righty’s development. The decision to initially use Dollander behind an opener, whether it came from manager Warren Schaeffer or the front office, proved fruitful.
Coors Field remains the most difficult place to pitch in the league. Per Statcast, it has a 112 overall Park Factor over the past three seasons, which ranks first by a significant margin. Chase Field is second on the list at 105. Colorado’s stadium ranks first in park effect for runs, OBP, hits, singles, and doubles, which makes sense given the spacious dimensions. The thin air in Denver also limits the effectiveness of breaking balls, forcing pitchers to reconsider their arsenals.
The Rockies have had the occasional pitcher break through with a productive season, despite the difficult home environment. Kyle Freeland finished eighth in ERA with a 2.85 mark in 2018. Jon Gray had a pair of sub-4.00 ERA seasons in the late 2010s. Jorge De La Rosa and Jhoulys Chacin formed a formidable duo in 2013, each posting sub-3.50 ERAs over 30+ starts. ERA is far from the only relevant pitching stat, but it’s a reliable marker for a successful season in a venue that boosts run production like no other.
Ubaldo Jimenez stands out as one of the only starters to have extended success in Colorado. He’s the name that gets whispered whenever a Rockies pitcher brushes up against relevance. The righty entered the rotation on a full-time basis in 2008. He racked up 16.8 WAR (per Baseball Reference) over the next three seasons. The walks were a bit high, but Jimenez limited damage with the help of a diverse arsenal. The 2010 campaign was his masterpiece. Jimenez posted 221 2/3 frames of a 2.88 ERA with nearly a strikeout per inning. He earned an All-Star selection and finished third in NL Cy Young voting. Jimenez had better numbers on the road, but not by much. He held opponents to a .661 OPS and a .294 wOBA in 101 2/3 innings at Coors Field.
Jimenez was the rare pitcher to perform worse after leaving Colorado. He had one good year after getting traded to Cleveland, but didn’t find much success beyond his Rockies tenure. Jimenez did provide what would seem to be a viable blueprint for surviving at Coors Field: above-average velocity, a diverse arsenal, and a pitch mix that isn’t overly reliant on breaking balls. Dollander checks those boxes. He uses a changeup instead of a splitter, but the rest of the repertoire lines up with peak Jimenez. It’s around 60% four-seamer/sinker, 12% changeup, and then a smattering of breaking balls (slider/curveball/sweeper). Dollander has also improved his walk rate to 6.9%. Even in Jimenez’s stellar 2010, he issued free passes at a double-digit clip.
Dollander is just 28 appearances into his big-league career. It’s a seven-game sample of positive results. There’s plenty of season left for him to succumb to the Colorado conditions, which aren’t limited to home games. Rockies players also have to adjust to leaving the Denver altitude for road trips. But the formula is there for Dollander to conquer Coors Field.

NL West Notes: Susac, Bailey, Freeland, Dollander, Ryan
Daniel Susac went 2-for-5 in the Giants‘ 10-5 win over the Nationals yesterday, as the catcher is now hitting an absurd .524/.545/.714 over the first 22 plate appearances of his Major League career. Susac was a Rule 5 Draft pick initially from the Athletics organization before he was taken by the Twins and then immediately dealt to the Giants.
A big Spring Training performance clinched Susac’s roster spot and a role as Patrick Bailey‘s backup, yet Susac’s dream start is earning him more playing time, with starts in three of San Francisco’s last five games. On Thursday, Giants manager Tony Vitello told the San Francisco Chronicle’s Susan Slusser and other reporters that the team intends on “involving [Susac] as much as possible, see if we get into an every other day situation, or whatever it might be.”
Bailey has never shown much at the plate over his four MLB seasons, but he is off to a particularly ugly start by hitting only .128/.180/.128 in 50 PA. While Bailey’s elite defense has been reason enough to earn him starting catcher duties in the past, the Giants’ offense has struggled so much (Friday notwithstanding) that the club has nothing to lose by riding the hot hand in Susac.
More from around the NL West…
- Kyle Freeland‘s MRI on his inflamed left shoulder didn’t reveal any structural damage, Rockies manager Warren Schaeffer told the Denver Post’s Patrick Saunders and other reporters. Freeland was retroactively played on the 15-day injured list on April 13, and the good diagnosis means that the veteran southpaw likely won’t miss too much time. The injury interrupted Freeland’s strong start to the season, as he had a 2.30 ERA over his first three outings.
- Chase Dollander is another Rockies pitcher getting good early results, as the former third overall pick has a 3.32 ERA, 28.7% strikeout rate, and 7.5% walk rate over 19 innings. Dollander has yet to start any of his five appearances, however, and Schaeffer told Saunders and company that Dollander will continue pitching behind an opener for the time being. The manager’s logic is simple: Dollander is “having a lot of success” as a bulk pitcher. “He’s settled into a routine, and routines are very different from being in the bullpen and starting. Obviously, we want him to be a starter, long-term. But right now we don’t want to mess with the routine,” Schaeffer said.
- The Dodgers‘ Triple-A affiliate in Oklahoma City placed River Ryan on the seven-day injured list yesterday, and Jack Harris of the California Post indicated that the placement is likely due to a hamstring injury. Ryan posted a 1.33 ERA over his first 20 1/3 MLB innings in 2024, but a Tommy John surgery in August of that year sidelined the right-hander for the entirety of the 2025 campaign. Returning to action with Oklahoma City this year, Ryan’s excellent peripherals and a .450 BABIP over seven innings of work indicate that he has pitched much better than his 5.14 ERA would imply. The IL stint will delay his eventual return to Los Angeles in what will probably be a bullpen role, as there isn’t room for Ryan even in a six-man Dodgers rotation if everyone is healthy.
Rockies To Select T.J. Rumfield, Brett Sullivan
The Rockies will carry first baseman T.J. Rumfield and catcher Brett Sullivan on their Opening Day roster, manager Warren Schaeffer announced over the weekend (link via Thomas Harding of MLB.com). Colorado also tabbed Ryan Feltner as their fifth starter, meaning Chase Dollander will begin the season in the bullpen.
It’s the first major league call for the 25-year-old Rumfield. Colorado added the lefty-swinging first baseman in a trade with the Yankees in January. They sent hard-throwing reliever Angel Chivilli to New York. A former 12th round pick who went unselected in December’s Rule 5 draft, Rumfield isn’t a highly touted prospect. He’s coming off a strong season in Triple-A, though, and the Rockies offered a much clearer path to playing time than he would’ve had behind Ben Rice and Paul Goldschmidt in the Bronx.
Rumfield hit .285/.378/.447 with 16 homers across 587 plate appearances in the minors last season. He worked walks at a 12% clip while striking out at a lower than average 18.4% rate. Rumfield’s middling batted ball metrics probably held him back from getting a look as a Rule 5 draftee. His 36.6% hard contact rate and 87.8 mph average exit velocity would be at the lower end for an MLB first baseman.
At the same time, Rumfield doesn’t have much more to prove against minor league pitching. He has posted above-average numbers at every stop, including nearly two full seasons in Triple-A. He’s an advanced contact hitter with a quality approach. That was on display this spring as well. Rumfield batted .280 with four homers and remarkably struck out just one time in 58 plate appearances in camp.
There’s a decent chance he’s the starting first baseman on Opening Day. Colorado had the worst first base group in the majors a year ago. They moved on from Michael Toglia over the winter, acquiring Rumfield and Edouard Julien as options at the position. Julien could also factor in at second base depending on how the Rox use utility player Willi Castro.
They can move Castro between second and third, though Schaeffer announced that infielders Ryan Ritter and Kyle Karros also made the team. They account for two bench spots, while Sullivan wins a third as the backup catcher. (The final bench spot is undetermined, as infielder Tyler Freeman is questionable for Opening Day with back soreness.) Sullivan beat out Braxton Fulford for the #2 catcher role; the latter was officially optioned yesterday.
Colorado added Sullivan on a minor league deal over the winter. The 32-year-old played in three big league games with the Pirates last year. He has 43 games and 112 MLB plate appearances under his belt, batting .204/.250/.291 with a pair of home runs. Sullivan had a big camp, hitting .378 with a pair of homers and three walks and strikeouts apiece in 16 games. Fulford hit .270 with three longballs, eight strikeouts and one walk.
Sullivan showed enough that the Rox want to keep him around to back up Hunter Goodman. He’s out of options, so he’ll need to stick on the MLB roster or be exposed to waivers. The Rockies will need to officially select Rumfield’s and Sullivan’s contracts on Wednesday. They can do so without designating anyone for assignment. Pierson Ohl and RJ Petit recently underwent Tommy John surgeries and can be placed on the 60-day injured list.
Meanwhile, the news on the pitching side comes as a surprise. Feltner and Dollander were competing for the final rotation spot behind Kyle Freeland and free agent signees Michael Lorenzen, Jose Quintana and Tomoyuki Sugano. Neither pitcher seized the job during camp. Feltner gave up 13 runs while walking 10 batters in 11 2/3 innings. Dollander surrendered 11 runs (10 earned) with seven walks and three hit batters across 14 frames.
Given Dollander’s pedigree as a former top 10 pick, it seemed that a rebuilding Colorado team would prefer to have him continue to start. They’ve opted for Feltner instead but apparently don’t believe Dollander would benefit from working out of the Triple-A rotation. He’ll join Antonio Senzatela as a multi-inning arm out of the bullpen.
Aside from Freeman’s health, the bullpen is the last unknown part of the Opening Day roster. There a couple middle relief spots up for grabs and one out-of-options player (Keegan Thompson) trying to maintain his spot on the 40-man roster.
Rockies Notes: Rotation, Gordon, Amador
The Rockies made a pair of camp cuts on Tuesday, optioning right-hander Tanner Gordon and second baseman Adael Amador. Both players will open the season in Triple-A Albuquerque.
Gordon made 15 starts a year ago, holding a rotation spot throughout the second half. The 28-year-old righty allowed a 6.33 ERA with a modest 18.4% strikeout rate. Gordon pitched well this spring, striking out 12 against two walks across 11 innings. He only surrendered eight hits and two runs. It wasn’t enough to overcome last year’s regular season production to hold a spot in a revamped Colorado rotation.
The Rockies signed Michael Lorenzen, Jose Quintana and Tomoyuki Sugano to one-year deals. They’ll all hold rotation spots behind Kyle Freeland, whom the Rox have tabbed as their Opening Day starter for a third straight season (and franchise-record fifth overall). That leaves one spot in the season-opening staff up for grabs.
Thomas Harding of MLB.com writes that the Rockies still haven’t decided whether they’ll go with Ryan Feltner or Chase Dollander. Feltner is the more experienced pitcher and made 30 starts with a 4.49 ERA and league average peripherals back in 2024. He was limited to six MLB appearances last year by injury, most notably back spasms.
Dollander is coming off a frustrating rookie season, allowing a 6.52 ERA across his first 21 starts. He pitched fairly well on the road (3.46 ERA with a 22.2% strikeout rate in 52 innings) but was destroyed for 55 runs over 46 frames at Coors Field. The 24-year-old Dollander is a former top 10 overall pick who is one of the most important players with the organization in a complete rebuild.
Neither pitcher has done much to impress this spring. Dollander has walked seven and hit three batters in 14 innings. He has given up 11 runs (10 earned) on 18 hits with 10 strikeouts. Feltner has been rocked for 13 runs with 10 walks in 11 2/3 frames. Gordon handily outperformed both of them in camp, but he’s a lower-ceiling pitcher whom the front office evidently wasn’t seriously considering for a spot on the Opening Day roster.
The Rockies are expected to keep Antonio Senzatela in a long relief role. Dollander and Feltner both have minor league options. Whomever doesn’t win the fifth starter job will probably begin the season alongside Gordon in the Albuquerque rotation. Gabriel Hughes and McCade Brown are the other depth starters on the 40-man roster. They were both optioned out in early March.
As for Amador, it’s moderately disappointing that he didn’t win a roster spot. The switch-hitting infielder has been one of the team’s more well-known prospects for a few seasons. Amador hasn’t hit at all in 51 MLB games over the past two years, batting .176/.242/.250 through 164 plate appearances.
His Spring Training production (.229/.270/.429 with two homers in 12 games) wasn’t good. Amador is coming off a strong .303/.405/.478 season with more walks than strikeouts in Triple-A, though that comes with the caveat of Albuquerque’s very hitter-friendly environment. Colorado acquired Edouard Julien from the Twins and signed utilityman Willi Castro to a two-year free agent deal to factor in at second base. They can each move to a corner infield spot (first and third base, respectively) if the Rockies decide to take another look at Amador midseason.
Rockies Place Chase Dollander On Injured List
September 13: The Rockies today officially announced Dollander’s placement on the injured list with a left patella tendon strain. Blalock was recalled to the majors in a corresponding move.
September 12: The Rockies will place Chase Dollander on the injured list with a knee injury, reports Patrick Saunders of The Denver Post. The 2023 ninth overall pick would have been lined up to start Saturday’s game in San Diego.
Instead, it appears his rookie season will come to a slightly premature end. Dollander will technically be eligible to return in the final five days of the season, so it’s possible he makes one more start, but there’s no incentive for him to pitch through any kind of discomfort. He’ll likely finish his debut campaign with a 6.52 earned run average across 21 starts.
Dollander had a very difficult time pitching at Coors Field. He allowed nearly 10 earned runs per nine innings during his 11 home starts. His road numbers are much better. The 6’2″ righty pitched to a 3.46 ERA in 10 starts outside Denver. Dollander held opposing hitters to a .200/.297/.324 slash in his road starts. His strikeout (22.2%) and walk (11.3%) rates on the road aren’t as strong as the ERA or slash line, but there are at least some encouraging signs. That included a solid final appearance in Los Angeles on Monday, as Dollander held the Dodgers to one run on a lone hit with five strikeouts in as many innings.
The 23-year-old Dollander is the Rox’s most talented young pitcher. He’ll obviously need to be far more competitive at Coors Field to have long-term success. There’ll be plenty of opportunity to do so in a Colorado rotation that doesn’t project to be much better in 2026 than it was this season. Germán Márquez is likely to walk in free agency. Neither Tanner Gordon nor McCade Brown has pitched well enough to merit an Opening Day rotation spot. Antonio Senzatela performed so poorly this year that the Rox have demoted him to long relief. Dollander and Kyle Freeland should be joined by three offseason acquisitions.
Colorado will need to call up a fifth starter or run a bullpen game in Dollander’s place tomorrow. Bradley Blalock is on the 40-man roster and would probably be the choice if they recall a starting pitcher from Triple-A Albuquerque. Former first-round pick Gabriel Hughes could also be a consideration. He’s not on the 40-man but would need to be added this offseason if the Rockies don’t want to expose him to the Rule 5 draft. That could lead them to give Hughes a couple starts down the stretch, as they’re doing with Brown.
