Rockies Select Valente Bellozo
The Rockies announced that they have selected the contract of right-hander Valente Bellozo and optioned him to Triple-A Albuquerque. To open a 40-man spot for him, they placed right-hander RJ Petit on the 60-day injured list. Petit underwent Tommy John surgery recently and will miss the entire 2026 season.
Bellozo, 26, signed a minor league deal with Colorado in the offseason. When a team adds a player to the 40-man roster and immediately options him, it’s usually a sign that the deal had some sort of opt-out or upward mobility clause. Going this route prevents the player from getting away but also doesn’t require the team to bump anyone else off the active roster.
The righty didn’t have an especially strong camp, allowing 11 earned runs in 15 2/3 innings, but the Rockies presumably like his larger track record. He spent the past two years working in a swing role for the Marlins, tossing 150 innings over 45 games, including 19 starts. He allowed 4.20 earned runs per nine. His 15.2% strikeout rate was subpar but he limited walks to a 6.8% clip. The Rockies also might like his arsenal, as he has thrown six different pitches in his career, something the organization is seemingly trying to prioritize this year.
Miami outrighted him off the roster at the end of last season and he elected free agency, which led to his deal with the Rockies. Colorado’s pitching was historically bad last year. They have tried to make it more respectable for 2026 by signing Michael Lorenzen, Jose Quintana and Tomoyuki Sugano. Those three are joining Kyle Freeland and Ryan Feltner in the rotation to start the season. Chase Dollander is beginning the campaign in long relief.
The optionable rotation depth includes Carson Palmquist, Gabriel Hughes and Tanner Gordon. Now Bellozo will jump into that mix. Teams generally need 10 to 15 starters to get through an entire season these days, so Bellozo and those other guys should have opportunities throughout the year.
As for Petit, the Rockies selected him with the first pick in last year’s Rule 5 draft. Due to his surgery, he’ll spend the entire year on the IL. The IL goes away five days after the World Series. If he sticks on the roster through the offseason, the Rule 5 restrictions would carry over until he has spent 90 days on the active roster.

Rockies Outright Keegan Thompson
5:12pm: Thompson has already cleared waivers and is indeed accepting the outright assignment to Triple-A Albuquerque, reports Thomas Harding of MLB.com. Although Colorado announced the DFA this afternoon, they apparently placed him on waivers earlier in the week.
12:37pm: The Rockies announced they’ve designated reliever Keegan Thompson for assignment. The right-hander is out of options and didn’t win a spot in Warren Schaeffer’s bullpen. Colorado selected the contracts of backup catcher Brett Sullivan and rookie first baseman T.J. Rumfield, each of whom was informed they’d made the team over the weekend. Thompson’s DFA cleared one spot on the 40-man roster, while the other was opened with Pierson Ohl (Tommy John surgery) going on the 60-day injured list.
Colorado also optioned hard-throwing righty Seth Halvorsen, who walked 12 batters in five innings this spring. They made five more season-opening IL placements. First baseman Blaine Crim (left oblique strain), utility player Tyler Freeman (back tightness), and outfielder Zac Veen (right knee contusion) all land on the 10-day injured list. Righties McCade Brown (shoulder inflammation) and RJ Petit (Tommy John surgery) open on the 15-day injured list. Colorado will move Petit to the 60-day IL whenever they need a 40-man roster spot. Freeman’s injury means first baseman/outfielder Troy Johnston claims the last bench role.
Thompson’s DFA wasn’t motivated by 40-man concerns but rather his out-of-options status. The Rockies opted to carry Jaden Hill and Zach Agnos in middle relief over Halvorsen and Thompson. They’re dedicating long relief roles to Chase Dollander and Antonio Senzatela. Trade pickup Brennan Bernardino is their only left-hander in the group, while they’ll use Jimmy Herget, Juan Mejia and Victor Vodnik in the late innings.
Colorado claimed Thompson off waivers from the Reds in January. He was on a split contract with Cincinnati that would have paid $1.3MM if he made the MLB roster and $350K for time spent in the minors. The Reds tried to sneak him through waivers but the Rockies placed a claim to take a look at him in camp. The 31-year-old righty had a tough spring, allowing 10 runs with six free passes (five walks and a hit batter) against four strikeouts over 12 innings.
There’s a decent chance Thompson sticks in the organization. He’ll likely go on waivers this week. If he clears, he’s unlikely to decline a minor league assignment and walk away from his $350K Triple-A salary. Thompson spent all of last year at the Triple-A level in the Cubs’ system. He turned in a 4.50 ERA while striking out nearly 30% of opponents across 64 innings.
Poll: Who Will Win The NL West?
With Opening Day just around the corner, the offseason is more or less complete for MLB’s 30 clubs and teams. Until the playoffs begin, teams will be focused on a smaller goal: winning their division. In the run-up to the start of the season, we will be conducting a series of polls to gauge who MLBTR readers believe is the favorite in each division. The Blue Jays came out on top in the AL East, and the Tigers did the same in our poll on the AL Central. Yesterday, MLBTR readers overwhelmingly voted (66%) to predict the Mariners would win the AL West. Today, we’ll be moving on to the National League, starting with the NL West. All teams are listed in order of their 2025 regular season record:
Los Angeles Dodgers (93-69)
The Dodgers may have not even qualified for a playoff bye last year, but their dominant performance during the postseason quelled any doubt about the club being the class of the National League. Los Angeles did not rest on its laurels this offseason, adding two more superstars: outfielder Kyle Tucker and closer Edwin Diaz. That duo levels up a roster that already sports Shohei Ohtani, Freddie Freeman, Yoshinobu Yamamoto, and Mookie Betts among many other high-end players. As has become the norm, the Dodgers enter 2026 as the overwhelming favorite to win the division, although their aging and injury-prone core will surely start showing cracks at some point. Will this year be that year?
San Diego Padres (90-72)
On paper, the Padres might look to some as if they’re more likely to miss the playoffs entirely than overtake the Dodgers in the NL West. The silver living for San Diego, then, is that this was also true headed into the 2025 season. Despite that narrative, the Padres managed to spend much of the summer in a virtual tie with Los Angeles, and they were in sole possession of first place as late as August 23. This year, they’ll look to defy the odds once again with a patchwork rotation that offers little certainty outside of Nick Pivetta and a lineup that wasn’t substantially improved over the offseason. The biggest additions to San Diego relative to last year, in all likelihood, will be full seasons from star closer Mason Miller and veteran outfielder Ramon Laureano.
San Francisco Giants (81-81)
After a splashy trade for Rafael Devers last June, the Giants ended up selling at last year’s trade deadline. Their efforts to get back in the playoff hunt for 2026 this winter were more complementary than impactful. Tyler Mahle and Adrian Houser join a rotation that lost Justin Verlander. The lineup added a glove-first outfielder in Harrison Bader and a bat-first infielder in Luis Arraez. Still, the team looks solid on paper. Those additions leave the San Francisco offense without many obvious holes, and the rotation sports one of the game’s best starters in Logan Webb plus a former Cy Young winner in Robbie Ray. Perhaps the biggest question facing the Giants this year is in the bullpen. San Francisco traded Tyler Rogers and Camilo Doval last July and lost Randy Rodriguez to Tommy John surgery in September. None have been replaced. That could leave the club bleeding runs in the late innings without big steps forward from players like Erik Miller and Jose Butto.
Arizona Diamondbacks (80-82)
Just about everything that could go wrong on the pitching side did so for the Diamondbacks last year. Zac Gallen had the worst season of his career. Corbin Burnes, Justin Martinez, and A.J. Puk all underwent elbow surgery. Brandon Pfaadt and Eduardo Rodriguez had seasons to forget. Their team is weaker on paper headed into 2026 than it was in 2025, as their big offseason additions were reunions with Gallen and Merrill Kelly, plus additions at the infield corners (Carlos Santana and Nolan Arenado) won’t match the offensive output of those positions’ previous occupants (Josh Naylor and Eugenio Suarez). Even so, Ketel Marte and Corbin Carroll are legitimate superstars. Geraldo Perdomo might be one as well. If the team’s veteran pitchers can turn things around, perhaps the Diamondbacks could ride their strong offensive nucleus back into the postseason.
Colorado Rockies (43-119)
Following a 119-loss season in 2025, Colorado made some small moves under new front office boss Paul DePodesta but nothing that would truly move the needle. Jake McCarthy, Edouard Julien, Willi Castro, Michael Lorenzen, and Jose Quintana have certainly all had their fair share of success in the past, but each profiles as a complementary player at the best of times. Perhaps those moves working out plus steps forward from key pieces like Brenton Doyle and Ezequiel Tovar could help the Rockies avoid another 100-loss season, but a division title or Wild Card berth are both pipe dreams.

Parker Mushinski Re-Signs With Rockies
March 24: The Rockies announced Tuesday that Mushinski has re-signed on a new minor league contract. He’ll presumably open the season with their Triple-A club.
March 22: Left-hander Parker Mushinski was in camp with the Rockies on a minor league deal but is now heading back to free agency. Thomas Harding of MLB.com reports that the southpaw has been informed that he won’t break camp with Colorado and will now opt out of his deal.
Mushinski, 30, had a camp of extremes. He racked up some strikeouts but also saw a lot of runs cross the plate. In 8 2/3 innings, he struck out 12 opponents but allowed ten earned runs via 11 hits and four walks. His .391 batting average on balls in play and 41% strand rate point to some poor luck in that small sample.
The Rockies had an awful pitching staff in 2025 and certainly had room for some new arms but they couldn’t find a spot for Mushinski. They’ll go into 2026 with Brennan Bernardino as the only lefty in their bullpen. Luis Peralta and Welinton Herrera are on the 40-man roster but will begin the season on optional assignment.
Mushinski’s major league track record consists of 33 innings pitched for the Astros over the 2022 through 2024 seasons. In that time, he has a 5.45 earned run average, 17.4% strikeout rate, 8.1% walk rate and 45.2% ground ball rate. He spent the 2025 season with the Guardians on a minor league deal. He tossed 50 Triple-A innings with a 3.78 ERA, huge 29.6% strikeout rate and strong 47.9% ground ball rate, but an ugly 14.8% walk rate.
He’ll head to the open market to see what opportunities await him now. There’s a ton of roster shuffling happening this week as clubs make their final decisions before Opening Day. As some guys get released or head to waivers, some clubs may find themselves light on lefty relief.

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 Release John Brebbia
The Rockies announced that right-hander John Brebbia has been released from his minor league deal. It’s unclear if he triggered an opt-out or was simply let go. In either case, he’ll head to free agency in search of his next opportunity.
Brebbia has some good seasons on his track record but is coming off a couple of rough campaigns, which is why he had to settle for a minor league deal with Colorado, no pitcher’s first choice for a landing spot. He was looking to bounce back but his results in camp were mixed. On the one hand, he struck out 11 of the 37 batters he faced, a strong 29.7% clip. He hit one batter but did not issue a walk. On the other hand, he allowed three home runs. That led to seven earned runs crossing the plate in nine innings.
That evidently wasn’t enough for him to earn a spot with the Rockies, so he’ll be looking for opportunities elsewhere. The interest he receives will mostly be based on his past results. As mentioned, his recent work hasn’t been great. Since the start of 2024, he has a 6.41 earned run average. From 2017 to 2023, he logged 299 2/3 innings with a 3.42 ERA, 25.5% strikeout rate and 7.2% walk rate.
Since his past two seasons have been such a challenge, he’ll surely be limited to minor league offers in the coming days. He may even circle back to the Rockies on a new deal. Those kinds of reunions are fairly common when guys get cut just before Opening Day.

RJ Petit Undergoes Tommy John Surgery
Rockies right-hander RJ Petit underwent Tommy John surgery with an internal brace on Friday, per Thomas Harding of MLB.com. He will miss the entire 2026 season and likely part of 2027 as well.
Petit, 26, was the top pick in the most recent Rule 5 draft. The Tigers left him unprotected even though he had just finished a strong 2025 season. He tossed 66 1/3 innings between Double-A and Triple-A with a 2.44 earned run average, 29.5% strikeout rate, 8.2% walk rate and 42.1% ground ball rate. While Petit was doing that, the Rockies were losing 119 games, therefore getting the top Rule 5 pick.
The righty made a few spring training appearances but it was revealed a couple of weeks ago that he had suffered a sprain of his ulnar collateral ligament. It seems that Petit and the Rockies took some time to consider the options before it was decided that surgery was necessary.
Petit should be placed on the 60-day injured list whenever the Rockies need a 40-man roster spot. He’ll spend the 2026 season earning big league pay and service time. The 60-day IL goes away five days after the World Series, so the Rockies would need to give him a spot at that time or else put him on waivers. If he clears waivers, he would have to be offered back to the Tigers.
Normally, a team gains full control of a Rule 5 player after holding him for a full season. However, the player has to be active for at least 90 days. If the Rockies want to keep Petit, they would have to keep him on the roster throughout the 2026-27 offseason. They could theoretically put him on the injured list to start the 2027 campaign and then activate him once he’s healthy. If were healthy in time to be active for 90 days in 2027, they would then gain his full rights. That would end the Rule 5 parameters and the Rockies could then option him to the minors.

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’ RJ Petit Suffers UCL Sprain
Rockies right-hander RJ Petit has been diagnosed with a sprained ulnar collateral ligament in his right elbow, the team announced to reporters at their spring complex (via Thomas Harding of MLB.com). He’s being sent for further evaluation before next steps are determined. Every case is different, of course, but the majority of UCL sprains result in surgery, be it an internal brace to stabilize/strengthen the existing ligament or a full UCL reconstruction (Tommy John surgery). The Rockies have not yet said whether surgery is an option for Petit.
Petit was the top pick in this December’s Rule 5 Draft. The Rockies plucked the towering 6’8″ righty from the Tigers system after Detroit left him unprotected despite a strong minor league track record. In 66 1/3 innings between Double-A and Triple-A this past season, Petit notched a 2.44 earned run average with a hefty 29.5% strikeout rate against a nice 8.2% walk rate. He sits 95 mph with his four-seamer, and that velocity plays up further due to the extension he gets from that 6’8″ frame and his long limbs. He allowed three runs in four spring innings prior to sustaining the ligament injury.
The Rockies had hoped that Petit could claim a spot in a wide-open bullpen mix that opened up even further with the offseason trade of Angel Chivilli and the elbow injury to DFA pickup Pierson Ohl (which will require Tommy John surgery). Petit will instead be looking at a notable absence, regardless of whether he requires surgery.
If the Rockies want to hang onto Petit, they’re able to do so. He can be placed on the 60-day injured list and spend the entire season there if need be — so long as the team is willing to give him major league service time and pay for that IL time. In that scenario, Petit’s Rule 5 designation would carry over into the 2027 season. The Rockies would thus be unable to option him to the minor leagues until he spent at least 90 days on the active roster.
For a club in the Rockies’ position, that may not be a dealbreaker. The overhauled Colorado front office, led by new president of baseball operations Paul DePodesta and general manager Josh Byrnes, certainly isn’t viewing the 2026 season as one in which the club will be competitive. They liked Petit’s arm enough to take him with the top pick in the Rule 5 Draft, and even in the unfortunate event that he’s out until next season, they’d still control the right-hander through at least 2031 after he meets the criteria to shed that Rule 5 status.
Brenton Doyle Battling Wrist Sprain
Rockies center fielder Brenton Doyle has a sprained left wrist, reports Thomas Harding of MLB.com. The defensive stalwart has sat out the last three Spring Training contests after experiencing soreness pregame on Wednesday. He’ll continue to rest for a few days before heading for follow-up examination.
There’s no indication at this point that Doyle’s availability for Opening Day is in jeopardy. That probably won’t be known until he’s reevaluated. The two-time Gold Glove winner has a month to get ready for the start of the regular season. The Rockies haven’t provided any specifics on the severity.
Doyle is looking to rebound offensively after a rough year. He hit .233/.274/.376 across 538 plate appearances, ranking among the bottom five hitters in MLB in on-base percentage (min. 500 PAs). It was a disappointing follow-up to a more encouraging 2024 campaign. Doyle had connected on 23 homers and stolen 30 bases while batting .260/.317/.446 two seasons ago. The slash line was right around average after accounting for the Coors Field effect.
If Doyle can get back to near league average at the plate, he’d be a very valuable all-around player. He’s a good baserunner and, as the aforementioned hardware illustrates, among the best defensive players in the sport. The Rockies have gotten trade calls on the 27-year-old but understandably didn’t have interest in what would have been a sell-low trade over the offseason. Doyle qualified for early arbitration as a Super Two player and is making a $3.1MM salary. The Rockies have him under contractual control through the 2029 season.
A healthy Doyle will be Warren Schaeffer’s primary center fielder. If the injury is serious enough that it impacts his regular season availability, the Rox would probably move offseason trade acquisition Jake McCarthy to center. Jordan Beck, Mickey Moniak, Zac Veen and Tyler Freeman could split the corner outfield work.
