Cubs Place Shota Imanaga On IL Due To Hamstring Strain

By | at

May 5: Imanaga has been placed on the 15-day IL with Gavin Hollowell recalled to take his place on the active roster, per Maddie Lee of the Chicago Sun-Times.

May 4: Cubs left-hander Shota Imanaga sustained what the team described as a left hamstring strain during today’s start against the Brewers.  With one out in the sixth inning, Imanaga picked up the injury while covering first base during a fielder’s choice from Milwaukee’s Christian Yelich.  Imanaga was immediately favoring his hamstring even before the play was completed, and was removed from the game after consulting with team trainers.

More imaging and tests need to take place before the Cubs decide whether or not Imanaga will head to the 15-day injured list, 670 The Score’s Bruce Levine writes.  Chicago has an off-day this coming Thursday, so conceivably, the team could skip Imanaga’s next turn in the rotation to give him some time to recover without putting him on the IL and losing him for at least 15 days.

That said, the fact that the injury has already been described as as strain certainly makes it seem like a 15-day IL stint is the most probable result.  With Imanaga likely out of action and Justin Steele already gone for the season due to UCL surgery, Chicago is now down its top two projected starters.

Signed to a four-year, $53MM contract during the 2023-24 offseason, Imanaga’s move from Nippon Professional Baseball to the majors went very smoothly, as he delivered a 2.91 ERA over 173 1/3 innings in his first big league season.  The lefty was off to another good start in his sophomore season, as counting today’s outing, Imanaga has a 2.82 ERA in 44 2/3 innings.  That quality ERA does mark some troubling secondary numbers, however, as Imanaga’s 18.9% strikeout rate is well below average, and he has allowed a lot of hard contact.

Those metrics notwithstanding, Imanaga was still delivering good bottom-line results, and helping the Cubs rise to first place in the NL Central.  Jameson Taillon and Matthew Boyd have also pitched well, Colin Rea has performed well since being inserted into Steele’s rotation spot, and Ben Brown has been inconsistent but serviceable in covering innings.

Assuming Imanaga will indeed go on the IL, Chris Flexen might be the likeliest replacement, as he was already working as a starter at Triple-A before Chicago selected his contract to the big league roster earlier this week.  Flexen has thus far made one appearance with the Cubs (a three-inning relief outing in Friday’s 10-0 win over Milwaukee), and could be fairly easily stretched out again for a starting gig in Imanaga’s place.

If not Flexen, the Cubs could call Jordan Wicks up from Triple-A, or perhaps give star prospect Cade Horton his first taste of Major League action.  Javier Assad won’t be an option for perhaps several months, as Assad recently suffered a Grade 2 oblique strain while pitching on a rehab assignment for an earlier oblique strain suffered in Spring Training.

Cubs Sign Nicky Lopez, Designate Gage Workman

By | at

The Cubs announced Wednesday that they’ve signed infielder Nicky Lopez to a big league deal. Infielder and Rule 5 pick Gage Workman was designated for assignment to open a spot on the roster. Photographer Sam Bernero first spotted Lopez heading into Wrigley Field this afternoon and tweeted out a photo she snapped. Shane Riordan of 670 The Score subsequently reported that Lopez, an Octagon client, was signing a major league deal.

Chicago also selected the contract of recently acquired lefty Drew Pomeranz, optioned righty Gavin Hollowell to Triple-A Iowa and transferred lefty Justin Steele from the 15-day IL to the 60-day IL (thus opening a 40-man spot for Pomeranz). Steele recently underwent elbow surgery and will miss the remainder of the 2025 season, so his move to the 60-day IL was a formality.

Lopez was with the Cubs as a non-roster invitee in spring training but didn’t make the Opening Day club. He opted out of that deal and signed with the Angels, who needed some infield depth due to a handful of injuries. The Halos reinstated shortstop Zach Neto last week and designated Lopez for assignment, after which he elected free agency.

The 30-year-old Lopez appeared in five games and was hitless in six plate appearances in his short stint with the Angels. He’ll hope for a larger look with the Cubs, who have some questions in the infield after optioning struggling top prospect Matt Shaw and seeing the now-designated-for-assignment Workman struggle at the hot corner as well. Veteran utilityman Jon Berti has been seeing more time at third base recently, though he hasn’t hit much either — just .250/.344/.250 in an admittedly small sample of 32 plate appearances.

Lopez, like Berti, brings a versatile and high quality glove to the Cubs. He’s spent the bulk of his career in the middle infield where he grades as a plus-plus defender at both positions. He’s less experienced at third base but still has strong grades in nearly 400 frames there (7 Defensive Runs Saved, 6 Outs Above Average).

Excellent as Lopez is on the defensive side of the coin, his bat leaves plenty to be desired. He’s a career .247/.311/.313 hitter in 2352 plate appearances at the MLB level, and even that modest production is skewed by what now looks like a clear outlier campaign in 2021, when he batted .300/.365/.378. In three-plus seasons since that time, Lopez has limped to a .232/.301/.286 line between the Royals, Braves, White Sox and Angels.

Workman, 25, was selected out of the Tigers organization in December’s Rule 5 Draft and made the Opening Day roster after he hit .364/.420/.705 in 50 spring plate appearances. He hasn’t carried that outstanding production over to the regular season. He’s appeared in nine games but tallied only 15 plate appearances, during which he’s gone 2-for-14 with a walk. Workman never got a true look with the Cubs, which isn’t surprising, as it’s difficult for contending clubs to carry a career minor leaguer who can’t be optioned to the minors.

Workman is viewed as a plus defender at third base with plenty of raw power and too much swing-and-miss in his offensive profile. He spent the 2024 season with the Tigers’ Double-A affiliate, where he batted .280/.366/.476 with 18 homers, 30 steals, an 11.7% walk rate and a bloated 27.5% strikeout rate in his third season of action at that level. He’s yet to appear in a Triple-A game.

Now that he’s been designated for assignment, Workman will be placed on outright waivers and offered to the rest of the league (excluding the Tigers). If he goes unclaimed, he will by rule be offered back to the Tigers for $50K.

The veteran Pomeranz hasn’t pitched in the majors since 2021 due to a lengthy series of injuries. He inked a minor league deal with the Mariners in the offseason and tossed 9 2/3 frames with their Triple-A affiliate in Tacoma before being traded to the Cubs for cash. He allowed five earned runs (4.66 ERA) on nine hits and six walks (plus two hit batsmen) during that short stint with Tacoma. Clearly, Pomeranz’s command was an issue, but he also fanned 14 of his 43 opponents (32.6%) and sat 92.3 mph on his heater — a good bit north of the 90-91 mph he was sitting at during minor league stints with the Padres and Dodgers over the past two seasons.

The Cubs’ Bullpen Outlook

By | at

The Cubs entered spring training this year with their bullpen largely set. Offseason trade acquisitions of Ryan Pressly and Ryan Brasier added a pair of veteran righties — including a closer, Pressly — to the late-inning mix. Chicago signed lefty Caleb Thielbar to a one-year, $2.75MM deal. That trio joined Porter Hodge, Tyson Miller and Keegan Thompson as virtual locks. All three holdovers pitched very well in 2024, and the latter two are out of minor league options.

There are plenty of candidates for the remaining spots, the bulk of whom are on the 40-man roster already. Righty Julian Merryweather is coming off a poor showing in an injury-marred season that included an April rib fracture and season-ending knee surgery in September. He yielded 11 runs in 15 innings (6.60 ERA), but Merryweather was excellent in 2023, logging a 3.38 ERA and 32.3% strikeout rate in 72 innings for the Cubs. He’s also out of minor league options, which surely gives him a leg up on others. (Four scoreless spring innings with a 5-to-1 K/BB ratio so far isn’t hurting his cause, either.)

Others on the 40-man roster include righties Nate Pearson, Eli Morgan, Jack Neely, Daniel Palencia, Ethan Roberts and Gavin Hollowell. All have at least one minor league option remaining. However, the Cubs have at least one non-roster invitee who’s making a push for a spot: veteran righty Brad Keller.

Maddie Lee of the Chicago Sun-Times wrote yesterday that Keller’s average fastball is up more than three miles per hour this spring, sitting 96.3 mph and topping out at 98 mph. Pitching coach Tommy Hottovy and manager Craig Counsell both spoke highly of Keller’s stuff this spring, with the skipper noting to Lee that Keller has been “more than we expected” so far in camp. Keller’s four runs in seven innings of work don’t stand out, but teams are far more focused on raw stuff, velocity and command when looking at such a small sample. Keller has allowed only seven hits and a walk while punching out six hitters and inducing grounders at a 48% clip so far.

Patrick Mooney of The Athletic reports that Keller’s velocity jump and smoother mechanics have not only made him a legitimate consideration to break camp but made it “likely” that the team will add Keller to the roster. The veteran righty has a looming opt-out opportunity in his deal, so the Cubs will either have to select his contract to the big league roster or risk him landing with another team. His minor league pact comes with a $1.5MM base salary, per Mooney, making Keller an affordable addition to the relief corps if the team sees fit.

Adding Keller to the mix, however, comes with complications. Right now, the Cubs have six relievers who cannot be optioned to the minors in the running for bullpen spots: Pressly, Brasier, Thielbar, Miller, Thompson and Merryweather. Hodge has a full slate of minor league options remaining, but coming off a 1.88 ERA and 31.7% strikeout rate in 43 rookie innings, he’s not going anywhere. He’s locked into a seventh spot in the ’pen.

Effectively, unless the Cubs are willing to move on from Merryweather, they only have one bullpen spot available. Plugging Keller into that spot would render their bullpen largely static, barring injury. Keller has more than five years of MLB service (6.062, to be more specific). He can’t be optioned without his consent.

That level of bullpen inflexibility is tough for any team to manage. Early off-days in the season would help, but if the Cubs needed to call up a fresh arm at any point, they’d be left choosing between optioning Hodge or designating someone for assignment. It’s not an ideal setup.  (The Mets faced a similar situation with their bench when weighing whether to re-sign Jose Iglesias, which is largely why he ended up with the Padres.)

The situation would only grow murkier when righty Javier Assad is healed up from an oblique injury. Assad has been ruled out for Opening Day and is presumably IL-bound to begin the year. If he returns in April, however, he’d likely push righty Colin Rea from the fifth starter’s spot to a long relief role. Rea, like many of his teammates on the staff, can’t be optioned. The Cubs could technically option Assad, but he pitched 147 innings of 3.73 ERA ball out of the rotation last year; his strikeout, walk an home run rates all point to some regression, but Assad has still pitched well enough to this point in his career (3.40 ERA in 294 innings) that he can be considered a lock when healthy.

It’s always possible that further injuries sort the situation out organically. Injuries, particularly on the pitching side of things, are an inevitability for any team over the course of a six-week spring training and 162-game season. But with the bulk of the pitching staff healthy right now and minimal flexibility due to their lack of optionable arms, the Cubs seem like they’ll be forced into some decisions on those out-of-options arms sooner than later.

Cubs Claim Gavin Hollowell, Designate David Bote

By | at

The Cubs have claimed right-hander Gavin Hollowell off waivers from the Diamondbacks and optioned him to Triple-A Iowa. The Snakes had designated him for assignment a few days ago. To open a 40-man roster spot, the Cubs have designated infielder David Bote for assignment. Paul Sullivan of the Chicago Tribune was among those to relay the news on X.

Hollowell, 26, was drafted by the Rockies and was with that organization until recently. The Diamondbacks claimed him off waivers in June and now he moves via another waiver claim, this time landing with the Cubs.

The interest from clubs likely stems from his big strikeout numbers in the minors, though he has also given out a large number of walks and hasn’t yet transferred those punchouts to the major league level.

The Rockies put him into 30 games over the 2022 and 2023 seasons and he pitched 40 2/3 innings with a 6.20 earned run average. He struck out 21.5% of batters faced in that time and gave out walks at an 11.8% rate. But since the start of 2023, he has thrown 47 minor league innings and struck out 27.9% of batters faced. That’s come with an elevated 13% walk rate and a 4.60 ERA, but clubs are always interested in missing bats.

He still has one option year after this one, so the Cubs could give him a lot of rope in the minors to see if he can rein in his stuff. If he does so, he has less than a year of service time and therefore comes with many years of club control and is still far away from qualifying for arbitration.

Bote, 31, signed an extension with the Cubs in April of 2019, a five-year pact that guaranteed him over $15MM. He served in a multi-positional role for a while but his results eventually tailed off, at least partially due to some injury troubles.

He was outrighted off the roster at the end of 2022 with two guaranteed years still left on his deal. Since he had more than three years of service time, he could have elected free agency, but doing so would have meant walking away from the remaining money on his contract since he was shy of the five-year service mark. Naturally, he stayed with the club and has been with them in a non-roster capacity until they selected his contract again in June.

He has a solid .304/.333/.391 batting line in his 48 plate appearances this year but that’s being held up by an unsustainable .424 batting average on balls in play. He has no home runs in that time and a 4.2% walk rate.

With the trade deadline now passed, the Cubs will have to put Bote on waivers in the coming days. It’s unlikely that any club would claim him and take on the remainder of his contract. He’s making $5.5MM this year with still roughly $1.1MM left to be paid out. There’s also a $1MM buyout on a $7MM club option for 2025.

Bote is still shy of five years of service time, meaning he still doesn’t have the right to reject an outright assignment and keep all of his money. Assuming he passes through waivers unclaimed, he will presumably accept another outright assignment and provide the Cubs with depth in a non-roster capacity.

Diamondbacks Designate Gavin Hollowell For Assignment

By | at

The Diamondbacks officially announced their signing of infielder Luis Guillorme, which was reported earlier today. In corresponding moves, they optioned infielder Blaze Alexander and designated right-hander Gavin Hollowell for assignment.

Hollowell, 26, has never pitched for the D’backs at the big league level. He had spent his entire career with the Rockies until they put him on waivers in June. The Snakes claimed him at that time but mostly have kept him on optional assignment since then. He was briefly recalled at the start of July but was optioned back down to Triple-A Reno a day later without getting into a game.

The Snakes were likely intrigued by his big strikeout numbers in the minors. Those have sometimes come with plenty of walks, which was certainly the case after switching organizations. In 17 1/3 Triple-A innings since coming to the Diamondbacks, he has a 3.63 earned run average and 30.4% strikeout rate but a huge walk rate of 16.5%. Combined with his time in the Rockies’ system earlier this year, his 2024 season consists of 23 2/3 minor league innings with a 5.70 ERA, 29.5% strikeout rate and 16.1% walk rate.

Those control issues weren’t as bad in previous seasons. He tossed 96 minor league innings over the 2021 to 2023 period with an even 3.00 ERA, 32% strikeout rate and 8% walk rate. He also tossed 40 2/3 major league innings for the Rockies with a 6.20 ERA, 21.5% strikeout rate and 11.8% walk rate.

He’s now been squeezed off Arizona’s roster. With the trade deadline in the rear-view mirror, they will have to put him on waivers in the coming days. Though the control hasn’t been there this year, his strikeout stuff could intrigue some clubs around the league. If he is claimed, he will still have an option year remaining after this campaign, giving him some future roster flexibility. He also has less than a year of major league service time, meaning a claiming team could control him well into the future.

Diamondbacks Place Jordan Montgomery On Injured List

By | at

The D-Backs shook a few things up in advance of their series with the Dodgers. Arizona reinstated catcher Gabriel Moreno from the 10-day injured list and designated backup Tucker Barnhart for assignment. (Nick Piecoro of the Arizona Republic reported those forthcoming moves over the weekend.)  The Snakes placed starter Jordan Montgomery on the 15-day injured list, retroactive to June 29, on account of right knee inflammation. Arizona also optioned young infielder Blaze Alexander to Triple-A Reno. Center fielder Alek Thomas is back from the 10-day IL, while the D-Backs recalled righty Gavin Hollowell to take a spot in the bullpen.

Montgomery has had a nightmarish season. The veteran southpaw agreed to terms on a $25MM pillow contract just before Opening Day. As with fellow late signee Blake Snell, he has had significant struggles with that abbreviated ramp-up. Montgomery agreed to head to Reno for a few starts as a tune-up. He was recalled in mid-April but hasn’t found anything close to his typical form.

Over 13 starts, Montgomery carries a 6.03 ERA in 65 2/3 innings. He’s striking out a well below-average 15.1% of opposing hitters. Montgomery had punched out more than 21% of batters faced in each of the previous three seasons. He allowed fewer than four earned runs per nine in each year while combining for a 3.48 ERA over 94 starts. The average velocity on his sinker is down from its customary 93 MPH range to 91.7 MPH.

It’s impossible to know how much of Montgomery’s struggles are attributable to the unconventional start to the season. It seems fair to presume that has played some role. Whatever the primary cause, Montgomery hasn’t provided anything close to the kind of production Arizona envisioned. The D-Backs hoped he’d step in as a mid-rotation replacement after Eduardo Rodriguez suffered a Spring Training lat strain. Instead, he’s been arguably the weakest point in a starting staff that remains the team’s biggest question mark.

Arizona recently welcomed Zac Gallen back from the injured list. They’re still without Rodriguez and Merrill Kelly. Righty Brandon Pfaadt has been solid, but the D-Backs haven’t gotten much out of Slade Cecconi and Ryne Nelson. They’ll need to find a fifth starter this week, as Arizona doesn’t have another off day until the All-Star Break. That might be righty Cristian Mena. Alex Weiner of AZ Sports tweets that Mena is with the big league club in Los Angeles, though he’s not yet on the roster. Acquired from the White Sox for Dominic Fletcher over the winter, the 21-year-old Mena has a 4.90 ERA with a 24.4% strikeout rate in 16 Triple-A starts. Joe Mantiply will kick off a bullpen game tonight; Montgomery had been slated to start tomorrow’s contest.

On the position player side, Moreno and Thomas draw back into the lineup. The former had a minimal IL stay with a thumb sprain. He’ll return to his role as the primary catcher. Barnhart’s DFA means the D-Backs will stick with José Herrera in the #2 catching role. Thomas has missed the bulk of the season because of a hamstring strain. He played in only four games before going down. That pushed Corbin Carroll into center field. Carroll should move back to right field, which could cut into the playing time for Jake McCarthy and Randal Grichuk.

It pushes Alexander off the MLB roster for the time being. The 25-year-old logged a good chunk of playing time at shortstop while Geraldo Perdomo was on the shelf. Upon Perdomo’s return, manager Torey Lovullo suggested he’d get Alexander more playing time at third base while cutting into Eugenio Suárez’s workload. Alexander got regular run for about two weeks but fell into a slump, hitting .138 without an extra-base knock in 33 plate appearances. Suárez has started five of the past six games at the hot corner. With Kevin Newman playing reasonably well as a utility option who cannot be optioned, the D-Backs send Alexander back to Reno for more consistent playing time.

Diamondbacks Claim Gavin Hollowell From Rockies

By | at

The Diamondbacks have claimed right-hander Gavin Hollowell off waivers from the Rockies, per announcements from both clubs. Arizona already had a 40-man vacancy after designating Logan Allen for assignment last week and have optioned Hollowell to Triple-A. There was no previous indication that Hollowell had lost his spot with the Rockies, so their 40-man count drops to 39.

Hollowell, 26, is a 2019 sixth-rounder who made his big league debut with the Rox in 2023. He’s pitched 40 2/3 innings in the majors across the past two seasons but been hit hard, yielding a 6.20 ERA with a below-average 21.5% strikeout rate and a hefty 11.8% walk rate. He’s also been quite homer-prone, serving up an average of 1.99 round-trippers for every nine innings pitched.

It’s not a strong big league track record, but Hollowell has punched out 32.8% of his opponents in the minors, including a 34% strikeout rate in 48 2/3 Double-A frames and a 26% strikeout rate in 27 1/3 Triple-A innings. Hollowell has averaged a fairly unremarkable 94 mph on his sinker and 93.4 mph on his four-seamer, but the velocity of both pitches plays up because of his enormous 6’7″ frame. He’s also shown solid command throughout his time in professional ball, walking only 8.2% of his opponents in the minors.

Hollowell is in the second of three option years, so Arizona will be able to freely shuttle him between Triple-A Reno and the majors both this season and next. Scouting reports at FanGraphs, Baseball America and MLB.com have tabbed Hollowell as a future reliever with solid command and the potential for an above-average four-seamer (with plus spin) and slider. The Snakes will hope that the change in scenery can not only bolster their own relief corps but also take a potential future contributor away from a division rival.

Rockies Designate Dinelson Lamet For Assignment

By | at

The Rockies designated right-hander Dinelson Lamet for assignment, MLB.com’s Thomas Harding reports (via Twitter).  Righty Gavin Hollowell was called up from Triple-A to take Lamet’s spot on Colorado’s roster.

Yesterday’s 8-1 loss to the Braves saw Lamet charged with all eight runs over four innings of work, and it was just the latest in a series of rough outings for the 30-year-old this season.  Lamet has an 11.57 ERA over 25 2/3 frames, which breaks down as a 10.80 ERA over 15 innings as a starter and a 12.66 ERA in 10 2/3 innings out of the bullpen.  He worked as a reliever before spending most of May on the 15-day IL with lower back tightness, and despite the lack of results, Lamet got a look as a starter due to Colorado’s dire need for rotation help.

The experiment didn’t work out, leaving Lamet possibly on his way out of the organization altogether.  It’s another rough turn in the career of a player who seemed like one of baseball’s breakout arms when he finished fourth in NL Cy Young voting as a member of the Padres in 2020.  Injuries kept Lamet off the mound entirely for big chunks of both the 2021 and 2022 campaigns, however, to the point that San Diego moved Lamet into a full-time relief role as an attempt to help keep him healthy.

The Padres dealt Lamet to the Brewers as part of the Josh Hader trade last summer, and after Milwaukee quickly DFA’ed Lamet, the Rockies claimed the righty off waivers.  Because he has more than five years of MLB service time, Lamet has the right to refuse an outright assignment to the Rockies’ Triple-A affiliate if he clears waivers this time around, and Lamet would still get to keep the remainder of the $5MM salary he is owed for the 2023 season.  Another team would be on the hook for that money if it claimed Lamet, and given his struggles, it is more likely that he’ll go unclaimed.

Rockies Notes: Profar, Bard, Hollowell

By | at

Jurickson Profar made his Rockies debut in today’s 3-1 loss to the Padres, and as fate would have it, Profar’s first game with his new team happened to be against his former team.  Playing with the Padres “was everything to me,” Profar told Jeff Sanders of the San Diego Union-Tribune, and seemed to express some regret over opting out of his $7.5MM player option to stay with the Padres in 2023.  “If I was a normal free agent, not opting out, it’s different.  Opting out and free agency taking that long, I always wanted to stay….I didn’t want to (opt out), but I did,” Profar said.

The entry into free agency took a long time to resolve, as Profar didn’t reach an agreement with Colorado until March 19 on a one-year, $7.75MM deal.  Rockies hitting coach Hensley Meulens was a key recruiter in the process, as Meulens has been a longtime mentor to Profar dating back to the earliest days of his baseball career in Curacao, and Meulens managed Profar as part of the Netherlands’ team in the World Baseball Classic.  Profar is looking forward to now joining Meulens in the majors, and getting off a fresh start with his new organization.

More from the Mile High City, as the Rockies are 2-2 following their split of the season-opening series with the Padres…

  • Manager Bud Black told media (including MLB.com) that Daniel Bard threw a bullpen on Saturday, and hit 96mph during the session.  It’s a positive sign for the veteran reliever, who began the 2023 campaign on the 15-day injured list due to a return of the anxiety issues that put Bard’s career on hold for several seasons.  There isn’t yet any timetable for Bard’s return, as naturally the Rockies will give him all the time he needs.
  • The Triple-A Albuquerque Isotopes placed Gavin Hollowell on the 10-day minor league IL today, and Danielle Allentuck of the Denver Gazette (Twitter link) reports that the right-hander is dealing with forearm tightness.  While the severity of the injury isn’t yet known, any sort of forearm issue is naturally troubling for a pitcher, and it adds to a tough week of news for Hollowell — Allentuck notes that he just missed out on a spot in Colorado’s Opening Day bullpen.  A sixth-round pick for the Rockies in the 2019 draft, Hollowell made his MLB debut last season, posting a 7.71 ERA in seven innings over six appearances.  MLB Pipeline ranks Hollowell as the 24th-best prospect in the Rockies’ farm system, and feels the 6’7″ reliever’s strikeout potential gives him promise, though his control is a work in progress.

Rockies Select Gavin Hollowell

By | at

The Rockies announced that they have selected the contract of right-handed pitcher Gavin Hollowell, while fellow righty Alex Colomé will go to the bereavement list in a corresponding move. The club already had a vacancy on their 40-man roster.

Hollowell, 24, was selected by the Rockies in the sixth round of the 2019 draft. He made an appearance in rookie ball that year before the minor leagues were canceled by the pandemic in 2020. He returned to official games in 2021, though was limited by injury to just 24 innings. He fared well in that limited action, largely in A-ball, putting up a 2.25 ERA with a 34.4% strikeout rate and 7.3% walk rate.

This year, he’s finally been able to have a normal season, throwing 48 2/3 innings out of the bullpen for the Double-A Hartford Yard Goats. In that time, he’s registered a 3.14 ERA with an excellent 34% strikeout rate and a strong 7.4% walk rate. Baseball America had Hollowell on their list of top 30 Colorado prospects both last year and coming into this year, complimenting his 95 MPH fastball and mid-80s power slurve. He’s also currently #40 on the Rockies’ list at FanGraphs.

With the Rox well out of contention and just over two weeks left on the schedule, the club can use that time to take a look at how Hollowell’s stuff plays in the big leagues. He’ll be making his major league debut as soon as he gets into a game.

Thomas Harding of MLB.com tweeted the roster moves prior to the official announcement.
