• Right-hander Jordan Sheffield went unclaimed on outright waivers and has been assigned to Triple-A Albuquerque, the Rockies announced. Selected by the Rox out of the Dodgers organization in the 2020 Rule 5 Draft, the hard-throwing Sheffield has thrown 31 1/3 innings of 3.16 ERA ball in the big leagues across the past two seasons, though there’s plenty of reason to be skeptical of that number. Sheffield has fanned just 16.9% of his Major League opponents — against an unsightly 12.1% walk rate. While he doesn’t have an especially loud contact profile, Sheffield has benefited from a .226 average on balls in play he’s unlikely to sustain. He’s also struggled immensely in 18 2/3 career Triple-A frames: 10.61 ERA, 23 hits (eight home runs), 18 walks and just 15 strikeouts. Sheffield will remain in the Rockies organization but will no longer occupy a spot on the 40-man roster.
• Blue Jays righty Matt Peacock, designated for assignment last week when the team signed Jackie Bradley Jr., has cleared waivers and been assigned outright to Triple-A Buffalo, per the transactions log at MLB.com. Peacock, 28, hasn’t pitched for the Jays this year but did log 10 innings between the D-backs and Royals, during which time he yielded six runs on a dozen hits and four walks with six punchouts. Peacock has a 4.95 ERA in 96 1/3 big league innings, mostly coming with Arizona, and has recorded a massive 59.3% grounder rate in that time. He has only a 13% strikeout rate but also a solid 7.4% walk rate. In parts of five minor league seasons, Peacock has a 3.71 ERA.

Sheffield, a former supplemental first-round pick of the Dodgers, landed in Colorado over the 2020-21 offseason via the Rule 5 draft. He spent all of last season in the majors, as required for a team to retain a Rule 5 pick’s rights. Sheffield worked as a low-leverage arm for skipper Bud Black, pitching to a 3.38 ERA across 29 1/3 innings. His strikeout and walk rates (17.2% and 11.2%, respectively) didn’t align with that quality run prevention. Nevertheless, Sheffield averaged 96.4 MPH with top-of-the-scale raw spin on his four-seam fastball, making him an interesting long-term relief option for the Rox.

Things have fallen apart during the Vanderbilt product’s second year in the organization. He’s made only two big league appearances, with his fastball velocity sitting at a diminished 93.7 MPH. He’s been blasted over 21 appearances with Triple-A Albuquerque, posting an 11.21 ERA with just a 16.3% strikeout rate and a huge 19.6% walk percentage. He’s also surrendered eight home runs in only 17 2/3 innings.

The Rockies will place Sheffield on waivers over the next few days. He’s never previously been outrighted, meaning the organization could keep him around without requiring a 40-man roster spot if he goes unclaimed. That seems likely, given the extent of his struggles in Triple-A this season.

Sep. 4: The Rockies announced a series of roster moves today, including the placement of left-hander Austin Gomber and first baseman/outfielder Connor Joe on the 10-day injured list.  According to MLB.com’s Thomas Harding, Gomber will be moved to the 60-day IL tomorrow when the Rockies select the contract of right-hander Ryan Feltner from Double-A, as Feltner will make his MLB debut by taking Gomber’s spot as the scheduled starter against the Braves.

Right-hander Jordan Sheffield has been activated off the 60-day IL, making his return after first hitting the IL on June 5 due to a right lat strain.  In addition, infielder Joshua Fuentes has been called up from Triple-A.

Gomber is suffering from spondylolysis, or a stress fracture in his lower back (also known as pars defect).  The 60-day IL placement will end Gomber’s first Colorado season on a painful note, though he did make a solid accounting of himself in his first full season as a starter.

Acquired from the Cardinals as part of the Nolan Arenado trade, Gomber provided some silver lining for disgruntled Rockies fans by posting a 4.53 ERA/4.28 ERA over 115 1/3 innings.  Gomber missed a month due to forearm tightness, and it’s fair to speculate that Gomber’s back problems may have impacted his recent performance, as the southpaw has a 8.50 ERA over his last four starts and 18 innings.  Looking at the Statcast numbers, Gomber’s strikeout and walk rate are roughly middle-of-the-road, though he has been good at limiting hard contact.

Joe left Friday’s game due to his injury, which has now been termed as a right hamstring strain.  As manager Bud Black told reporters (including The Athletic’s Nick Groke), “it’s not a definite season-ending injury,” so Joe could potentially see some more action in 2021 if his hamstring cooperates.  Signed to a minor league contract last winter, Joe has hit well over 211 plate appearances with the Rockies, batting .285/.379/.469 with eight home runs.

Feltner was Colorado’s fourth-round pick in the 2018 draft, and the Ohio State product will make the jump to the majors without the benefit of any Triple-A experience.  In 110 combined innings at high-A and Double-A ball this season, Feltner has a 2.62 ERA and 27.53% strikeout rate over 20 starts.  The big league promotion is a nice late birthday present for Feltner, who turned 25 last Thursday.

JUNE 19: Rockies left-hander Austin Gomber left tonight’s start after two innings due to left forearm tightness, the team announced.  The removal was made “for precautionary reasons,” specifically.  Gomber stayed in the game long enough to make a plate appearance in the bottom of the second inning, dropping down a sacrifice bunt.  (MLB.com’s Thomas Harding noted that Jhoulys Chacin was already warming up in Colorado’s bullpen before Gomber’s at-bat, so it doesn’t appear as though the injury occurred while Gomber was at the plate.)

Injuries have already led to one big setback in Gomber’s career, as he missed the entire 2019 season due to shoulder and biceps problems.  A forearm issue is naturally of major concern, and it could be that the Rockies were simply acting as quickly as possible in removing Gomber at the first hint of trouble.

The 27-year-old Gomber carried an outsized spotlight entering the season, as he was the only player with MLB experience amongst the four-player package the Rockies received from the Cardinals in the Nolan Arenado trade.  Colorado fans were notably displeased about pretty much every facet of that deal, though Gomber’s recent numbers have provided a silver lining.  After a slow start to the season, Gomber had caught fire, posting a 1.28 ERA over his last seven starts and 42 1/3 innings heading into tonight’s outing against the Brewers.

Gomber is under team control through the 2025 season, giving the Rockies either a rotation building block or potentially even a future trade chip (i.e. not at this year’s trade deadline) depending on whether or not the team embarks on a wide-scale rebuild.  A serious forearm injury, of course, would interrupt either of those scenarios.

8:29AM: Rockies right-hander Jon Gray left Friday’s game after 2 1/3 innings due to what manager Bud Black described as right elbow soreness and tightness in Gray’s forearm.  Gray was charged with five runs in the abbreviated outing, with the injury clearly a factor.

“When I spoke to Jon, he indicated that his soreness impacted his pitching,” Black told The Denver Post’s Patrick Saunders and other reporters.  “I don’t think he felt it on every pitch.  It started to tighten as the game went on.  That’s when we noticed the variability with his pitch-making and with his mannerisms.”

In the bigger picture, any sort of forearm or elbow issue is naturally a major concern for a pitcher.  It seems likely that Gray will miss at least one start for precautionary reasons if nothing else due to the nature of the injury, and a trip to the injured list shouldn’t be ruled out until Gray undergoes further testing and medical examination.  Gray has generally avoided any major arm injuries over the years, apart from the shoulder inflammation that prematurely ended his 2020 season in early September.

While it’s too early to ring the alarm on a potential Tommy John surgery, an injury that sidelines Gray for any noteworthy amount of time will have some ramifications on both his future and the Rockies’ trade deadline plans.  In the opinion of MLBTR’s Steve Adams, Gray is nothing less than the top trade candidate in baseball at this point in the season, owing to Colorado’s spot near the bottom of the standings, Gray’s decent numbers through 63 innings, and the righty’s impending free agent status.

An IL stint of anything more than a month or so would throw a wrench into Gray’s trade value, or perhaps prevent a deal altogether if teams are concerned about Gray’s arm.  Similarly, Gray’s ability to score a lucrative multi-year deal in free agency this winter could be hampered, perhaps to the point where he’d have to settle for a one-year deal.

Gray had been inconsistent in the three starts prior to last night’s injury-shortened appearance, and for the season, he has posted a 4.29 ERA/4.72 SIERA over 63 innings.  His 18.5% strikeout rate and 10% walk rate are both below average, but Gray’s overall Statcast outlook is not bad, and his 52.4% grounder rate is a career high.  Though Gray has been much better at Coors Field than on the road this season, he has some value as a potential change-of-scenery candidate who could perhaps thrive in a more normal pitching environment than the thin air of Colorado.

We’ll take a look at how the surviving Rule 5 draftees are faring periodically throughout the year. Here’s the first glance…

Currently in the Majors

• Brett de Geus, RHP, Rangers (via Dodgers): Injuries throughout the Rangers’ bullpen might have helped the 23-year-old de Geus crack the Opening Day roster in Texas. He’s out to a shaky start, having walked three batters and hit another three against just two strikeouts through his first 5 2/3 innings. On the plus side, 13 of the 15 balls put into play against him have been grounders.
• Akil Baddoo, OF, Tigers (via Twins): Baddoo is one of the best stories (maybe the best) of the young 2021 season. The 22-year-old homered on his first swing in the big leagues as his family rejoiced in the stands, and in less than two weeks’ time he’s added a grand slam, a walk-off single (against his former organization) a 450-foot dinger off Zack Greinke and a fourth homer. Baddoo has a ludicrous 1.342 OPS through his first 29 plate appearances in the Majors, and while he obviously won’t sustain that, he’s forcing a legitimate audition in the Detroit outfield. Baddoo missed nearly all of 2019 due to Tommy John surgery and didn’t play in 2020. Despite that layoff and the fact that he’d never played above A-ball, the Tigers called his name in December. It may have seemed like a stretch at the time, but it doesn’t look that way now.
• Garrett Whitlock, RHP, Red Sox (via Yankees): The Sox would surely love for Whitlock to stick, having plucked him from their archrivals in New York. So far, so good. Better than good, in fact. Through 6 1/3 scoreless innings, Whitlock has yielded three hits and punched out nine batters without issuing a walk. He’s sitting 95.6 mph with his heater and has posted a hefty 16.9 percent swinging-strike rate. Whitlock also had Tommy John surgery in 2019, so even though he’s previously been a starter, it makes sense to monitor his workload ease him into the mix as the Sox hope to get through the year with him in the ’pen.
• Tyler Wells, RHP, Orioles (via Twins): Wells has allowed a pair of homers and surrendered three total runs on four hits and two walks with five strikeouts in 5 2/3 frames. The O’s aren’t trying to win in 2021, but their bullpen also has four arms that can’t be optioned (Cesar Valdez, Shawn Armstrong, Adam Plutko, Wade LeBlanc). Keeping both Wells and Mac Sceroler (currently on the IL) brings them  to six and will hamper their flexibility.
• Zach Pop and Paul Campbell, RHPs, Marlins (via Orioles and Rays): Pop was technically the D-backs’ pick in the Rule 5, but Arizona immediately flipped him to the Marlins for a PTBNL. The 24-year-old didn’t allow an earned run in five spring frames but as I was finishing this post, he served up a three-run homer, bringing his season line to seven runs on three hits, three walks and two hit batters in 3 1/3 innings. Campbell has struggled to a similar extent. He’s surrendered five runs (three earned) and given up four hits and three walks in just 2 2/3 innings. With the Marlins out of tank mode, it’ll be tough to carry both all year.
• Jordan Sheffield, RHP, Rockies (via Dodgers): Sheffield was the No. 36 overall pick in the 2016 Draft, but control issues prevented him from being protected on the Dodgers’ 40-man roster. FanGraphs’ Eric Longenhagen gives Sheffield three plus pitches in his scouting report (fastball, curveball, changeup) but also pegs his command at a 30 on the 20-80 scale. Sheffield has walked or plunked 15 percent of the hitters he faced in the minors. He’s yet to walk anyone 13 batters he’s faced with the Rockies, but he did hit one and has also tossed a pair of wild pitches. That said, he’s also sitting 95.5 mph with his heater and is unscored upon in 3 2/3 frames.
• Luis Oviedo, RHP, Pirates (via Indians): Oviedo was the Mets’ pick at No. 10, but they had a deal worked out to flip him to the Pirates in exchange for cash. Oviedo has been hammered for six runs on six hits (two homers) and two walks with five strikeouts through 4 2/3 innings so far. Even pitching for a tanking club, Oviedo will need to show some improvement in order to stick on the roster all season.
• Will Vest, RHP, Mariners (via Tigers): The Mariners kept last year’s Rule 5 pick Yohan Ramirez for the whole season, but it’ll be tougher to do with a full schedule in 2021. The Mariners’ young core is also beginning to rise to the big leagues, and Vest will need to fend off some intriguing young arms. He’s done a decent job so far, allowing a pair of runs (one unearned) on five hits and four walks with five strikeouts in 7 1/3 innings.
• Trevor Stephan, RHP, Indians (via Yankees): Stephan whiffed 16 of 44 hitters this spring to earn a spot on the Indians’ Opening Day roster, but he’s allowed four runs in his first four MLB frames. The 25-year-old has surrendered five hits (including a homer), walked a pair and hit a batter so far while facing a total of 21 hitters.
• Ka’ai Tom, OF, Athletics (via Indians): Tom, 26, raked at a .310/.412/.552 pace with a homer, two doubles and a triple in 34 spring plate appearances. After that strong audition, however, he’s just 1-for-16 with six strikeouts through his first 16 trips to the plate with the A’s.

On the Major League injured list

• Jose Soriano, RHP, Pirates (via Angels): It wasn’t a surprise to see Soriano open the year on the injured list. He’s still recovering from Tommy John surgery performed in Feb. 2020 and didn’t pitch in a game with the Pirates this spring. He’ll be sidelined for at least the first two months, as the Bucs put him on the 60-day IL to open a 40-man roster spot when they signed Tyler Anderson. Soriano hasn’t pitched above A-ball, but the Pirates aren’t exactly a win-now club, so they can afford to stash him as a seldom-used bullpen piece in order to secure his rights beyond the 2021 season.
• Mac Sceroler, RHP, Orioles (via Reds): Sceroler fanned six hitters in 3 2/3 innings early in the season but also yielded three runs on five hits (two homers), three walks and a hit batter. The Orioles recently placed him on the 10-day injured list due to tendinitis in his right shoulder, although it’s not expected to be too lengthy an absence.
• Dedniel Nunez, RHP, Giants (via Mets): Nunez was hit hard in the Cactus League, surrendering four runs in 3 1/3 innings. He’ll now miss the entire 2021 season after sustaining a UCL tear that required Tommy John surgery this spring. Nunez will spend the season on San Francisco’s 60-day injured list and receive a year of MLB service, but he’ll still be subject to Rule 5 restrictions in 2022 once he’s healthy. He’ll need to spend at least 90 days on the MLB roster before he can be sent to the minors; if he doesn’t last that long, he’ll have to pass through waivers and, if he clears, be offered back to the Mets.

Returned to their original club

• Jose Alberto Rivera, RHP, Angels (via Astros): The Angels didn’t take much of a look at Rivera, returning him to Houston on March 24 after just one inning of official work in Cactus League play.
• Kyle Holder, SS, Reds (via Yankees): The Reds weren’t sure who their shortstop was going to be heading into Spring Training, but they ultimately settled on moving Eugenio Suarez back to that spot, sliding Mike Moustakas back to third base and giving prospect Jonathan India the nod at second base. A strong spring from Holder might have at least given him a bench spot behind that trio, but he hit just .219/.359/.250 in 39 plate appearances. The Reds returned him to the Yankees on March 30.
• Gray Fenter, RHP, Cubs (via Orioles): The Cubs returned Fenter to the Orioles on March 12 after just one spring appearance. He hasn’t pitched above A-ball yet.
• Dany Jimenez, RHP, Athletics (via Blue Jays): The 27-year-old Jimenez was a Rule 5 pick in consecutive offseasons — once by each Bay Area club. The A’s returned him to the Jays on March 15, however, after he yielded four runs (two earned) in three innings of work this spring.

Sheffield, 21, garnered solid pre-draft rankings from prospect experts, with Callis and colleague Jonathan Mayo placing him 19th, Baseball America (subscription required) 23rd and ESPN’s Keith Law (Insider required) 31st. Law actually had Sheffield ending up with the Dodgers in his June 9 mock draft, but with the 32nd pick instead of the 36th. Sheffield is perhaps the likeliest pitcher in this year’s draft to develop three plus offerings, according to Callis and Mayo, who praised his high-velocity fastball (94 to 96, with the ability to hit 98), breaking ball and circle change. However, the 6-foot, 185-pounder’s size, past Tommy John surgery and high-effort delivery are red flags, per Callis and Mayo.

Sheffield, the brother of Indians left-handed prospect Justus Sheffield, was previously a 13th-round pick of the Red Sox in 2013 after his stock fell because of his Tommy John procedure. However, in lieu of signing with the Sox, he chose to honor his commitment to Vanderbilt. He recovered from the surgery to rebuild his stock at the college level and will now join the Dodgers. With Sheffield locked up, the Dodgers have their first 12 picks – and 16 of their initial 17 selections – under contract, as Bill Plunkett of the Orange County Register tweets.
