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.

Cardinals Claim Luis Peralta
The Cardinals have claimed left-hander Luis Peralta off waivers from the Rockies, according to announcements from both clubs. Colorado designated him for assignment last week. The Cards had an open 40-man spot and have optioned Peralta to Triple-A Memphis, so no corresponding moves are necessary.
Peralta, 25, is the younger brother of Freddy Peralta. The younger sibling was a starter earlier in his career but got moved to a relief role when he was a minor leaguer with the Pirates. He showed tremendous promise in that role in 2024, the year he was traded to the Rockies in a one-for-one swap for Jalen Beeks.
Between the two clubs, he tossed 47 2/3 minor league innings that year, allowing only 0.94 earned runs per nine. He did give out walks at a high rate of 11.2% but his 40.1% strikeout rate was massive and his 48.8% ground ball rate above average as well. He also got to make his big league debut and put up a 0.73 ERA in 12 1/3 innings.
Things have been going downhill since then, however. He had a 9.47 ERA in the majors last year and a 9.09 ERA at the Triple-A level. For Albuquerque, his 28% strikeout rate was still pretty good but his 15.4% walk rate way too high. In the majors, things were even worse, as his ghastly 17.8% walk rate was higher than his 15.8% strikeout rate. He began 2026 back at Triple-A but but allowed 14 earned runs in 7 1/3 innings while walking 13 opponents.
His velocity is down a bit as well. His four-seamer averaged 95 miles per hour in 2024 but dropped about half a tick last year and is now down to 93.5 miles per hour so far in 2026. His curveball and changeup have had similar drops.
The Rockies eventually gave up. Perhaps that’s because the new front office is less enamored of Peralta but it’s hard to fault them when looking at Peralta’s recent numbers. For the Cards, despite a 14-13 record at the moment, they have long planned for 2026 to be an evaluation year. They are less focused on immediate contention and more worried about long-term development.
They’ve had an open roster spot since Jared Shuster was designated for assignment two weeks ago. They are using that today to grab Peralta. Obviously, Peralta’s stock is down at the moment, but the Cards will see if there’s a path to getting him back to that 2024 form. Peralta can be optioned for the remainder of this year and one additional season as well. If things click, he has less than a year of service time, meaning he could be affordably controlled for years into the future.

Rockies Place Ryan Feltner On 15-Day Injured List
The Rockies placed right-hander Ryan Feltner on the 15-day injured list on Friday, and called up left-hander Sammy Peralta from Triple-A in the corresponding move. Feltner is dealing with right ulnar nerve inflammation, which forced him out of his start on Thursday (a 10-8 Rockies loss to the Padres) after two innings of work.
Manager Warren Schaeffer described the issue as “just a little elbow inflammation” when speaking with MLB.com’s Bill Ladson and other reporters. Since Feltner’s “MRI looked pretty good,” the Rox are hopeful that the righty will be back after just a minimal 15-day absence.
Feltner allowed two runs in his abbreviated outing against San Diego, boosting his ERA to 6.30 over five starts and 20 innings this season. His 4.46 SIERA is almost two runs lower than his ERA and Thursday’s start could be considered a wash due to his injury, yet Feltner’s Statcast metrics are uniformly below average at this early point in the season. In particular, opposing batters have been laying into Feltner’s pitches to the tune of a 49.2% hard-hit ball rate and a 15.9% barrel rate.
As Ladson observed, injuries have been a persistent issue for Feltner during his career, including a 2025 season that saw the righty limited to 30 1/3 innings due to back spasms and a shoulder problem. The most frightening of Feltner’s injuries was a skull fracture and a concussion sustained after he was hit in the head by a Nick Castellanos line drive in May 2023, which resulted in another shortened season of only 43 1/3 frames.
The Rockies’ scheduled game with the Mets today has been rained out, and the two teams will play a doubleheader on Sunday. With the pitching schedule already a little scrambled, the Rox will likely get through the doubleheader and then Monday’s offday before addressing Feltner’s rotation spot. Kyle Freeland has been on the 15-day IL since April 13 due to some minor shoulder inflammation and could be back when first eligible, as Freeland tossed 41 pitches over a two-inning simulated outing on Wednesday.
Rockies Trade Nicky Lopez To Cubs
The Rockies announced they’ve traded minor league infielder Nicky Lopez to the Cubs for cash. He was on a minor league contract and will not immediately occupy a 40-man roster spot for Chicago.
Lopez has been an organizational favorite of the Cubs as a depth infielder. He appeared in 14 MLB games for them last year between April and May. Lopez had also been with the club last spring on a minor league deal before being granted his release to pursue an MLB opportunity with the Angels. The Cubs waived him in late May but brought him back on a new minor league contract in August.
The Naperville, Illinois native signed with Colorado in December. He’s out to a nice start with Triple-A Albuquerque, batting .333 with a home run and a couple stolen bases over 15 games. Although the offense is surely inflated by playing in the Pacific Coast League, he’s showing his typically strong bat-to-ball ability while playing in the middle of the diamond.
Lopez is a lifetime .245/.310/.311 hitter in a little under 700 big league contests. He’s a quality defender at any of second base, third base, or shortstop. If the Cubs wanted to call him back up, he could replace Scott Kingery (who still has a minor league option) as the team’s utility infielder. Chicago would need to select Lopez onto the 40-man roster but essentially has a free roster spot with Porter Hodge a lock to move to the 60-day injured list after this week’s UCL surgery.
Rockies Claim Blas Castaño, Designate Luis Peralta For Assignment
The Rockies have claimed right-handed Blas Castaño off waivers from the Mariners, according to announcements from both clubs. The righty had been designated for assignment by the Mariners a week ago. The Rockies have optioned him to Triple-A Albuquerque. In a corresponding move, left-hander Luis Peralta has been designated for assignment.
Castaño, 27, was originally an international signing of the Yankees out of the Dominican Republic. He was released in the summer of 2023 and scooped up by the Mariners. He impressed his new club in 2024, posting a 4.38 earned run average in 125 1/3 minor league innings, spending most of that in the hitter-friendly Pacific Coast League. He was added to the 40-man roster in November of 2024 to keep him from reaching minor league free agency.
He has spent the past year-plus as a depth arm for the Mariners without being needed much. He has only made one big league appearance, which was a three-inning relief outing in May of last year.
He tossed 126 2/3 innings for Triple-A Tacoma last year with a 5.19 ERA, in the unfriendly confines of the PCL. His 17.8% strikeout rate and 9.3% walk rate weren’t especially strong but he did induce grounders on 46% of balls in play. So far this year, he has been pitching out of the bullpen, throwing 6 1/3 innings over six appearances for the Rainiers. His 1.42 ERA in that small sample looks nice but his strikeout and ground ball rates are around the same level as last year.
The Mariners bumped him off their roster but the Rockies will take a shot on him. They may be attracted to his diverse pitch mix, something that has seemingly become an organizational preference. Statcast categorizes him as a five-pitch guy. He doesn’t throw his four-seamer often, leading instead with his sinker, in addition to a slider, cutter and changeup. His fastball and sinker average around 94 miles per hour, the cutter around 90, the changeup in the high-80s and the slider in the low-80s.
The Rockies could stretch him back out or keep in a relief role. They need pitching either way. They had a 5.99 ERA as a team last year, easily worst in the majors. They have a 4.40 mark so far this year, bumping them into them out of the bottom ten of MLB clubs, but in a much smaller number of games. Whether he’s working as a starter or a reliever, the Rockies can keep him at Triple-A until he’s needed. He can still be optioned for the remainder of this season and another season as well.
Peralta, 25, was acquired from the Pirates in the 2024 deadline deal which sent Jalen Beeks to Pittsburgh. Peralta, the younger brother of Freddy Peralta, showed some potential around the time of that trade but his stock has fallen.
Initially a starter, he was moved to a relief role by the Pirates. Between the Bucs and the Rockies, he tossed 47 2/3 minor league innings in 2024 with a 0.94 ERA. His 11.2% walk rate was high but he struck out 40.1% of opponents and induced grounders at a 48.8% clip. He also posted a 0.73 ERA in his first 12 1/3 big league innings.
2025 was a big step back, as he posted an ERA above 9.00 in both the majors and the minors. His 28% strikeout rate in Triple-A was still good but a big drop, while his walk rate climbed all the way up to 15.4%. In the majors, his 17.8% walk rate was worse than in the minors and also higher than his 15.8% strikeout rate, with both of those figures being well worse than average. So far this year, he has thrown 7 1/3 innings in Triple-A with a 31.1% strikeout rate but a 28.9% walk rate and 14 earned runs allowed.
Those struggles have nudged him off Colorado’s roster. DFA limbo can last as long as a week. The waiver process takes 48 hours, so the Rockies could take as long as five days to explore trade interest. His recent numbers are obviously not good but perhaps some clubs see a path to getting him back to the dominant form he showed in 2024. He still has options and could be sent to the minors if any club acquires him in the coming days.

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 Place Kyle Freeland On IL
The Rockies announced today that left-hander Kyle Freeland has been placed on the 15-day injured list, retroactive to April 13th, due to left shoulder inflammation. Fellow lefty Jose Quintana was reinstated from his own stint on the IL as a corresponding move.
Freeland was scheduled to start for the Rockies three days ago but he was scratched due to some tightness in his shoulder. Details on his health are still not clear but the Rockies will let him rest up for at least a few turns through the rotation.
It’s an unfortunate setback for Freeland personally. He was out to a strong start this year, with a 2.30 earned run average through his first three appearances. But beyond that, this reduces the chances of him triggering his $17MM vesting player option for 2027.
Unlocking the player option was always going to be tough, as Freeland needs to throw 170 innings this year. That’s a mark he has hit only twice in his career. Way back in 2018, he got to 202 1/3 innings. His second-best season in that category was 2022, when he only barely got there, finishing at 174 2/3. Last year, a minimal stint on the IL for a back injury knocked him out for 15 days. He took the ball 31 times and logged 162 2/3 innings.
Naturally, Freeland’s best path to hitting that benchmark would be to stay healthy and pitch deep into games. Any kind of injury setback, even a small one, reduces his chances of getting to that line.
Presumably, the Rockies wouldn’t want him to trigger that option. They are rebuilding, having lost 119 games last year, and don’t have strong motivation to spend at that level on a starting pitcher. They did bolster the rotation this winter by signing some pitchers but all to notably lower salaries than that. They gave Michael Lorenzen $8MM, Quintana $6MM and Tomoyuki Sugano $5.1MM. Even if they are willing to bring back Freeland next year, it would make sense for them to prefer to negotiate a salary, as opposed to Freeland having the freedom to just lock in $17MM.
In terms of the on-field results, it’s not a huge deal in the short term. Quintana missed a couple of weeks with a hamstring strain but slots right into Freeland’s position in the rotation. He is taking the ball tonight, followed by Sugano, Ryan Feltner, Chase Dollander and then Lorenzen.

Broncos’ Ownership Group Purchases Minority Share In Rockies
Penner Sports Group, a company run by the Penner family which owns the NFL’s Denver Broncos, has purchased a minority share in the Rockies. The MLB franchise announced the news this afternoon.
The Rockies specified only that the Penner investment made them the largest minority stakeholder under the Monfort family, which retains majority ownership. Patrick Saunders of The Denver Post provides specifics, reporting that the Penners are purchasing a 40% share of the franchise.
The team didn’t disclose the sale price, though Saunders writes that it’s believed to be around $672MM. The Rockies’ statement said the influx of cash allows them to “retire all outstanding debt while providing additional investment in the team.” It’s unclear if it’ll have any impact on player payrolls in the future. The Penners will remain focused on the Broncos and are not going to have daily responsibilities with the Rockies, Saunders reports.
Most of the major Denver sports franchises, the Broncos included, have been successful in recent years. The Rockies are coming off the first three 100-loss seasons in franchise history. They’ve had seven straight losing campaigns and dropped 119 games last year, tied for third-most in MLB history.
They’ve started this season respectably, going 6-7 while outscoring opponents by six runs, but are unlikely to be even a .500 club for some time. Colorado opened this season with a $117MM payroll, according to The Associated Press, the 21st-highest mark in the league. That’s down marginally from their $122MM season-opening figure in 2025.
Rockies Claim Sammy Peralta From Brewers
The Rockies have claimed left-hander Sammy Peralta off the Brewers’ waiver wire, Todd Rosiak of the Milwaukee Journal Sentinel reports. Colorado has officially announced the move, and shifted right-hander McCade Brown to the 60-day injured list to create space for Peralta on the 40-man roster. Peralta has been optioned to the Rockies’ Triple-A affiliate.
The Brew Crew designated Peralta for assignment earlier this week to open up a 40-man roster spot for the newly-acquired Luis Matos. Peralta’s tenure with the Brewers will end after two Triple-A appearances and zero big league games, as Milwaukee just claimed Peralta off waivers from the Angels last October.
Appearing in each of the last three MLB seasons, Peralta’s resume in the Show consists of 30 appearances and 45 2/3 innings with the White Sox and Angels from 2023-25. He has a 5.12 ERA, 17.3% strikeout rate, and 11.2% walk rate, and Peralta has averaged only 89.3mph on his fastball during his brief time in the majors.
Peralta drastically cut back on his fastball in 2025 and also cut back on his changeup usage, instead incorporating a sinker a third of the time and boosting his slider up to a 49% usage rate, without any real change in results. While his ERA jumped from 4.80 in 2024 with the Sox to 7.59 with the Angels in 2025, Peralta’s underlying metrics didn’t change much, so his change in pitch repertoire didn’t have any impact on his performance either under the hood or in terms of bottom-line results.
Peralta routinely pitches multiple innings in relief, making him a useful depth option for the Rockies’ bullpen. Brennan Bernardino is also the only left-hander in Colorado’s current relief mix, which could give Peralta some extra opportunity to stick with the team if and when he is eventually called up from Triple-A.
Brown started the season on Colorado’s 15-day IL due to shoulder inflammation, and the move to the 60-day IL ensures that his 2026 debut won’t come until at least the last week of May. 2025 marked Brown’s first taste of the big leagues, as he posted a 7.36 ERA over 25 2/3 innings and seven starts for the Rockies.
Rockies Place Jose Quintana On Injured List
The Rockies announced they’ve placed starter Jose Quintana on the 15-day injured list with a right hamstring strain. The move is retroactive to March 30, meaning he’ll be eligible to return on April 14. Colorado recalled righty Valente Bellozo from Triple-A Albuquerque in a corresponding move.
Colorado also optioned infielder Ryan Ritter this evening. They haven’t replaced him on the active roster but will do so tomorrow. Outfielder Mickey Moniak will be eligible for reinstatement from his 10-day injured list stint; he’ll presumably be the corresponding move.
The Rox are idle tonight before hosting Philadelphia for a three-game weekend series. Teams don’t typically announce minor transactions like this during off days. Injured list placements can be backdated by a maximum of three days, however, so the Rox would have delayed Quintana’s eligibility for reinstatement if they waited to make that move until tomorrow.
Quintana made his team debut on Monday against the Marlins. He allowed four hits and walked four batters in 4 1/3 innings. The veteran southpaw mostly managed to work around the traffic and only allowed two runs. He departed with a one-run lead, though Miami would win 4-3 on Owen Caissie’s walk-off two-run homer with two outs in the ninth.
There was no indication that Quintana was injured during the game. It’s unclear if the issue developed during a midweek throwing session. Michael Lorenzen will open the series against Aaron Nola tomorrow. Quintana was slated to oppose Jesús Luzardo on Saturday evening. Bellozo would be on six days rest after throwing three Triple-A frames on Sunday. He could step into Quintana’s rotation spot or work in long relief if they want to give Chase Dollander a couple turns as a starter.
