NL Notes: Nationals, Giants, Rockies, Marlins
Teams contacted the Nationals about third baseman Carter Kieboom this offseason, manager Dave Martinez told reporters (including Todd Dybas of NBC Sports Washington). Kieboom hasn’t found any success at the MLB level to date, but it’s no surprise rival clubs would have interest in the 23-year-old. Washington held onto the former top prospect, who looks like the favorite to open the season as the starter at the hot corner.
More from Washington and other Senior Circuit cities:
- Stephen Strasburg had a normal offseason, he told reporters today (via Mark Zuckerman of MASNsports.com). The Nationals star right-hander was limited to five innings last season by carpal tunnel syndrome in his throwing hand. Fortunately, the procedure he underwent last summer addressed the issue. The former World Series MVP will be a key piece in the Nats’ hopes of contending in a difficult NL East.
- Giants president of baseball operations Farhan Zaidi discussed the team’s newest addition to the pitching staff this afternoon (via Andrew Baggarly of the Athletic). Right-hander Shun Yamaguchi, who worked exclusively out of the bullpen last season for the Blue Jays, will come to camp as a starting pitcher. The 33-year-old can opt out of his minor-league deal at the end of spring training if he doesn’t make the team, Zaidi said. That’s a rather typical feature for non-roster arrangements.
- When Rockies outfielder Ian Desmond opted out of the 2020 season, Colorado signed Matt Kemp the following day. With Desmond announcing his intent to sit out in 2021 as well, some speculation had arisen the Rockies could again turn to Kemp, who is back in free agency. Colorado manager Bud Black cast doubt on the idea, though, telling reporters (including Patrick Saunders of the Denver Post) the organization hasn’t recently discussed signing Kemp, even though Desmond had notified the team he was considering opting out a few weeks ago.
- The Marlins signed Ross Detwiler to a one-year contract in January. Detwiler has started 95 games across his 12-year MLB career (including 12 starts for the 2019 White Sox). However, Miami views the veteran southpaw as strictly a bullpen option in 2021, manager Don Mattingly told reporters (including Craig Mish of SportsGrid). Detwiler worked solely in relief for Chicago in 2020, tossing 19.2 innings of 3.20 ERA/3.90 SIERA ball.
NL Notes: Nationals, Third Base, Coaching Announcements, Reds, Cubs
The Nationals have no qualms about Carter Kieboom as their starting third baseman despite an alarming lack of power, writes Mark Zuckerman of MASNSports.com. The 23-year-old has produced a meager .051 ISO over his first 165 plate appearances, including just a solitary double in 122 plate appearances in 2020. Kieboom hit 16 home runs in 2019 at Triple-A with a respectable .189 ISO, and Fangraphs gives him a 55-potential in-game power grade on a 20-80 scale. The Nationals believe the power will come. Luis Garcia, the Nats’ top offensive prospect after Kieboom, was rushed to the Majors in 2020, but he does not appear to be in serious consideration for an everyday role on the 2020 roster, notes Zuckerman. Starlin Castro enters camp as the starter at second base, while Josh Harrison lines up as the primary backup at all three non-first-base infield spots. The Nationals aren’t famous for boasting tremendous depth, though they do have non-roster invitees Jordy Mercer, Adrián Sanchez, and Hernán Pérez also in camp. Let’s check in on some coaching announcements in the National League…
- Jose Moreno, the Manager of the Year in the Venezuelan Winter League this season, will take over as manager for the High-A Dayton Dragons in the Reds’ system, per the Athletic’s C. Trent Rosecrans (via Twitter) and a press release from Dayton. It will be Moreno’s second season with the Reds after spending 19 years in the Seattle Mariners’ organization. As the Dragons make the move from Low-A to High-A, they’ll do so with with Darren Bragg, Brian Garman, and Daryle Ward on Moreno’s staff as a development coach, pitching coach, and hitting coach, respectively. Ward returns as the Dragons hitting coach after serving in the same role with the club in 2016 and 2017. Garman, meanwhile, was hired for the 2020 season before the cancellation.
- The Cubs announced their minor league coaches and coordinators for the 2021 season today. Among the additions, Dustin Kelly has taken over as minor league hitting coordinator after three seasons as a hitting coach in the Dodgers’ organization. He played three seasons in the minors after being drafted in 2004 by the Red Sox. Kelly replaces Chris Valaika, who was promoted to assistant hitting coach for the big league club, notes the Athletic’s Sahadev Sharma (via Twitter).
Nationals Open To Moving Carter Kieboom In Trade Talks
As the Nationals continue to explore their offseason trade options, the team is “definitely open” to including former top prospect Carter Kieboom in negotiations, The Athletic’s Britt Ghiroli reports (Twitter links). Right-handed pitching prospects Cade Cavalli and Jackson Rutledge, however, are not available.
Washington went into the 2020 season hoping Kieboom could step in as the new everyday third baseman, after Anthony Rendon left for the Angels in free agency. While nobody expected Kieboom to match Rendon’s All-Star level of production, the Nats surely hoped for more than the .202/.344/.212 slash line Kieboom delivered over 122 plate appearances. The lack of hitting led the Nationals to demote Kieboom to their alternate training site for just shy of two weeks, and his season was also shortened by a wrist injury in the final week of play.
Aside from a respectable OBP, there wasn’t much to like about Kieboom’s first extended taste of Major League action, as he didn’t make much hard contact and next to no power — Kieboom had the lowest slugging percentage of any player in baseball with at least 120 PA. However, Kieboom showed lots of pop in the minors, hitting .287/.378/.469 with 45 homers in 1462 PA in the Washington farm system after being drafted 28th overall in 2016.
Considering this prospect pedigree, Kieboom’s age (23) and the fact that the 2020 season was about the most difficult of possible circumstances for a younger player to acclimate himself to the big leagues, it is certainly very possible that Kieboom can break out in the near future. As such, Ghiroli notes that the Nationals surely aren’t going to “give him away” in any trade, if they were to deal him whatsoever. It’s probably safe to assume most teams also still see Kieboom as a valuable trade chip, so D.C. would only deal Kieboom as the centerpiece of a trade for an established MLB player — perhaps even at third base, to solidify that position.
Cavalli and Rutledge are widely seen as the top two prospects in a Washington farm system that is heavy on pitching, particularly right-handers. The sheer amount of depth makes it possible that the Nationals might be willing to discuss one of those less highly-regarded prospects (say, in the 5-10 range of their top ten list) but it also makes sense that they’re not budging on moving Cavalli or Rutledge, both first-round picks in the last two drafts.
East Notes: Arozarena, Eaton, Nationals, Sanchez
Randy Arozarena, infield prospect? The current Rays outfielder began his pro career in Cuba’s Serie Nacional as a second baseman during his teenage days, so his defensive future wasn’t exactly settled by the time the Cardinals scouted him as a Mexican League player. “Some of the question marks at the time were more on profile because he played second base, a tick of third base…and then when we saw him in Mexico when he was eligible to sign he was full-time playing center field and we had great looks there,” Cardinals assistant GM Moises Rodriguez told Baseball America’s Kyle Glaser. “Profile muddled the evaluation a little bit, but as far as strength and twitch in his swing, that was never in question.”
This offensive potential was enough to merit a $1.25MM bonus for Arozarena as part of the Cardinals’ 2016-17 international signing class, though Arozarena has long since left second base behind, and also left St. Louis last winter. The Cards dealt Arozarena to Tampa Bay as part of a multi-player trade that seemingly featured Jose Martinez and pitching prospect Matthew Liberatore as the headliners, yet it is Arozarena who has blossomed as a major piece of the 2020 club. After recovering from a bout of COVID-19 early in the season, Arozarena hit .281/.382/.641 with seven homers over 76 PA in the regular season, and has been even hotter during the Rays’ postseason run.
More from around both the AL and NL East…
- It seems possible that Adam Eaton has played his last game with the Nationals, MASNsports.com’s Mark Zuckerman writes that “you’d think they might prefer another corner outfielder with more pop than Eaton can provide.” Beyond just Eaton’s rough .226/.285/.384 slash line over 176 plate appearances in 2020, the Nats also figure to consider glovework and cost in deciding whether or not to bring Eaton back next year, and neither factor is necessarily in the veteran outfielder’s favor. Eaton’s defensive metrics took a significant step back this season, and exercising his 2021 club option is a $9MM choice for the Nats — Eaton’s option can be picked up for $10.5MM or bought out for $1.5MM. With a lot of money already committed to the 2021 team and several roster issues in need of being addressed, Washington might prefer to spread that $9MM around to multiple areas, though letting Eaton go would create another need in left field.
- Third base is another problem spot for the Nationals, as Todd Dybas of NBC Sports Washington notes. Carter Kieboom didn’t produce in his rookie year, leaving veterans Asdrubal Cabrera and Josh Harrison having to pick up the slack to mixed results. It’s obviously too early to give up on Kieboom, so Dybas suggests that the Nats could just sign another veteran on a short-term contract as a depth option if Kieboom again struggles. Conversely, the Nationals could make a bigger internal move by shifting Luis Garcia to third base, or look outside the current roster for a free agent signing either big (Justin Turner) or more modest (Jake Lamb).
- Gary Sanchez is “the biggest decision of the Yankees’ offseason,” George A. King III of the New York Post writes. Sanchez’s disastrous 2020 season has seemingly cost him the starting catcher job, and it remains to be seen if the Bronx Bombers still consider him as a part of their future. It doesn’t seem likely that the Yankees would simply non-tender Sanchez (owed a raise on his $5MM salary heading into his second arbitration year), yet a trade might not be out of the question. The Yankees would obviously be trying to shop Sanchez when his trade value is at its lowest, King notes, “yet, there is no guarantee the Yankees will ever be in position to sell high on Sanchez.” There is also the matter of finding a replacement at catcher — the Yankees are already looking at a second consecutive year with a big luxury tax bill, so splurging on J.T. Realmuto might not be feasible.
Carter Kieboom Done For Season
The Nationals have placed infielder Carter Kieboom on the 10-day injured list with a left wrist contusion and recalled right-hander Wil Crowe, the team announced. Kieboom’s IL placement is retroactive to Tuesday, but this will nonetheless end his season.
Kieboom was a first-round pick of the Nationals in 2016 who continues to be regarded as a high-end young talent, but this will go down as a disappointing season for him. The reigning World Series champions Nationals had designs on Kieboom capably replacing departed star Anthony Rendon at third base as early as this season, though the campaign has instead gone poorly for the sub-.500 Nats and the 23-year-old.
While Kieboom does lead Washington in playing time at the hot corner, where he has amassed 30 starts and 122 plate appearances, he could only put together a .202/.344/.212 line before his season ended. Kieboom failed to hit a home run this year, and with a mere one extra-base hit, he ranks last in isolated power (.010) among 243 major leaguers who have amassed 120-plus plate appearances in 2020.
Nationals Recall Carter Kieboom, Designate Wilmer Difo
The Nationals have designated infielder Wilmer Difo for assignment and called infielder Carter Kieboom back up from their alternate training site, the team announced. The move reinstalls Kieboom as the Nats’ everyday third baseman, manager Davey Martinez told MASNsports.com’s Mark Zuckerman and other reporters today.
Kieboom was optioned to the alternate site 10 days ago, making his stay in Fredericksburg a minimal one. The demotion raised some eyebrows at the time, though Kieboom had only hit .200/.359/.200 through his first 64 plate appearances for Washington this season. While the club may have been opting to use more experienced players than Kieboom in an attempt to turn the season around, the Nationals’ 2-10 record over their last 12 games has sunk them to last place in the NL East, and they now seem to be looking ahead to 2021.
Despite his lack of production (.535 OPS) over 107 PA at the big league level, the 23-year-old Kieboom is clearly still seen as a big part of the Nationals’ future. The 28th overall pick of the 2016 draft has posted a .287/.378/.469 slash line and 45 homers over 1462 minor league PA and has little left to prove on the farm, which is why D.C. was hoping Kieboom could slide right into an everyday role this season and at least somewhat fill the void left behind by free agent departure Anthony Rendon.
Since it seems like Kieboom will spend the rest of the season on Washington’s MLB roster, the youngster is still on pace to gain a full year of (prorated) service time, as Jesse Dougherty of the Washington Post notes. Kieboom’s demotion won’t, therefore, give the Nats an extra year of control over Kieboom’s services.
Now in his 11th season in the Nationals organization, Difo has a .247/.309/.348 career slash line over 1060 Major League PA, coming off the bench to play second base, shortstop, third base, and a handful of games in the outfield. After seeing semi-regular action in both 2017 and 2018, Difo spent much of last season in the minors, and he didn’t appear on the Nats’ postseason roster. Washington agreed to a $1MM salary for Difo in 2020, which was his first year of arbitration eligibility.
Nationals Option Carter Kieboom, Activate Sean Doolittle
The Nationals announced Wednesday that they’ve optioned struggling third baseman Carter Kieboom to their alternate training site in order to open a spot on the roster for lefty Sean Doolittle, who has been reinstated from the injured list.
Though Kieboom has yet to find his groove at the plate in 2020, it’s still a surprise to see the Nats option him out. The organizational hope had been that the 22-year-old, long considered one of MLB’s top overall prospects, could step into the Anthony Rendon-sized void in that lineup. That’s not to say that anyone expected the 2016 first-rounder to single-handedly make up for Rendon’s lost production, but Kieboom has been touted as a potentially plus hitter in his own right.
The future for Kieboom may still be bright, but he’s yet to find success in multiple big league auditions. He’s without an extra-base hit through 64 plate appearances this year, and he’s batted a combined .169/.299/.236 in 107 PAs dating back to last year’s debut. Clearly, that’s a far cry from last year’s .303/.409/.493 slash in 494 trips to the plate with Triple-A Fresno.
With Kieboom now out of the mix at third base and Starlin Castro on the shelf following surgery to repair a fractured wrist, the Nats will need to lean more heavily on the veteran trio of Asdrubal Cabrera, Josh Harrison and Howie Kendrick to carry the freight at second and third base. Kendrick has been limited to first base and DH exclusively in 2020, but he did appear in 23 games at second base and 15 games at third base during the 2019 regular season. Depending on how the Nats approach Monday’s looming trade deadline, we could see them look to add some infield depth — although starting pitching seems like a greater area of focus with Stephen Strasburg lost for the year and 60 percent of the rotation struggling to ERAs north of 5.00.
Nationals Notes: Kieboom To Start At Third, Denaburg Out, Cavalli In
Speaking to a handful of DMV-area reporters, Nationals’ manager Davey Martinez said that he expects Carter Kieboom to be the starting third baseman, MASN’s Mark Zuckerman, and Todd Dybas of NBC Sports were among those reporting. It’s a bit of a surprising revelation from Martinez, as last we heard, Kieboom wasn’t even a sure thing to make the Opening Day roster. At the same time, most projections had the 22-year-old making his play for the hot corner by August, surely, so it might be that not much has changed in terms of organizational outlook. More on this and the other goings-on around Nats’ camp…
- One change that might have affected the Nats’ plan for Kieboom, however, was Ryan Zimmerman opting out for the season. Without Zimmerman, there seems to be plenty of at-bats to go around the remaining veteran contingent of Nationals’ infielders. First base should fall to a strict platoon between Howie Kendrick and Eric Thames, while the off-day first baseman is also likely to split time at DH with Asdrubal Cabrera. Starlin Castro, then, would handle second base relatively full-time while occasionally being spelled by either Cabrera or Kendrick. The Nationals tend to let their prospects play full time, so if Kieboom keeps the starting role through Opening Day, he’s likely to get more-or-less the full slate of 60 games to prove he deserves it.
- Updating some numbers for us, Jesse Dougherty of the Washington Post mentions that the Nationals have about 49-50 guys in camp right now of the 58 currently named to the player pool. That said, the Nats’ are widely expected to add first-round pick Cade Cavalli to their 60-man player pool shortly, per TalkNats. The Nats have a few open spots on their roster now that a number of players have opted out for the season (Ryan Zimmerman, Joe Ross, Welington Castillo).
- As the Cavalli addition presupposes, the Nats have chosen to include most of the organization’s highest-regarded prospects in the 60-man player pool. That group would have included Mason Denaburg, were he not out for the season recovering from offseason surgery, per Stephen G. Mears of TalkNats. The 6’4″ former catcher ranks eighth on the Nats’ top prospect list per Baseball America. He was the Nats’ top draft choice in 2018, though he’s managed just 20 1/3 innings of pro ball since then.
Replacing Legends
If you trust Braves’ third base coach Ron Washington, Austin Riley has a long and bright future ahead of him with the Atlanta Braves, per The Athletic’s David O’Brien. Said Washington, “He’s a very, very special kid. He’s on that special level with Ozzie (Albies) and (Ronald) Acuńa (Jr.) and all those young guys. He’s on that special level with them.”
Given Washington’s stellar reputation as an infield instructor, his word carries some weight. He goes on in O’Brien’s article to laud not only Riley’s long-term future with the bat, but with the glove as well, calling Riley “a tremendous third baseman.”
While it’s certainly encouraging for Braves’ fans to hear Washington speak so highly of Riley after an up-and-down rookie season, the path ahead is not without obstacles. For starters, he hasn’t locked down his spot in the starting lineup. All accounts suggest he’s going to have to earn his keep while being pushed at third by Johan Camargo. After his first month of big-league action, it would have seemed unfathomable that Riley wouldn’t have the 2020 third base job locked down, but Camargo remains very much in the running, despite struggling himself in 2019. Camargo’s year was worth -0.6 rWAR after hitting only .233/.279/.384 over 248 plate appearances. He’s played much better in the past (4.4 fWAR from 2017 to 2018), and the Braves appear confident he can at the very least hold the line for a year.
Should Camargo get the bulk of playing time at third, Riley could get at-bats as a designated hitter – at least in theory. But O’Brien notes that the scuttlebutt out of Atlanta pegs Marcell Ozuna as the likeliest option to see heavy minutes as a potential DH. Makes sense with Ronald Acuna Jr., Ender Inciarte, and Nick Markakis on hand to handle the outfield rotation. Riley himself could even see some minutes out on the grass depending on how things shake out.
But the real question at hand here is this: is Austin Riley the third baseman of the future for the Atlanta Braves? Ron Washington certainly seems to think so. If we trust Washington’s eye for defensive talent and assume Riley can stick at third base (or even become a plus defender), the question is whether his approach at the dish can improve enough to take advantage of his otherworldly power.
After all, Riley’s power numbers last year were excellent. He managed a .471 SLG with 18 home runs in just 274 at bats. His isolated power was .245 ISO, well above average and a number you’d hope for out of a middle-of-the-order bat. For context, Acuna Jr. walked away from 2019 with a .238 ISO. A full season at Riley’s mark would put him among the top-40 mashers in the league by isolated power. His power plays.
But even with those numbers, Riley’s total offensive contribution amounted to 14 percent below league average by wRC+. He needs to round out the rest of his game – and that starts with cutting down strikeouts. Riley’s walk-to-strikeout numbers are not anywhere near where they need to be for everyday reps (5.4 BB%, 36.4 K%). Both numbers need to see significant positive regression. The good news is, Riley looked the part in spring training, where signs pointed to Riley being able to make the necessary adjustments.
Third base is a loaded position for Atlanta – in terms of poignancy – and Riley has big shoes to fill. Putting aside the big picture pressure of manning the spot once belonging to the legendary Chipper Jones, even recent history has set a high bar for Riley. Last season, Josh Donaldson returned to All-Star form with a .259/.379/.521 line, 37 rainmaking bombs, 96 runs, 94 RBIs, 132 wRC+, good for 4.9 fWAR/6.0 rWAR. Good luck replicating those numbers out the gate.
Elsewhere in the NL East, another legend moved westward after a memorable 2019. Anthony Rendon gave the Nationals seven underrated seasons at the hot corner before joining the Los Angeles Angels this winter. We could talk all day about Rendon’s performance this postseason, but those in Washington, Rendon-as-superstar was old hat: He’s been a 6+ fWAR performer for three seasons running. Beyond his consistency, there’s simply no replacing the slow-heartbeat clutch-hitting Rendon provided the Nats on their World Series run – but someone is going to have to try.
Enter Carter Kieboom. Rendon’s nominal heir apparent – at 22-years-old – is about half a year younger than Riley, and he comes sporting a shinier prospect pedigree. He’s the 21st ranked prospect overall by MLB.com and Fangraphs, while Baseball America puts him as the 15th overall prospect (admittedly, Riley wasn’t far off, topping out as Baseball America’s 22nd ranked prospect before last season).
Much like Riley, Kieboom’s role at the outset of whatever season comes next is TBD. There’s an even greater chance the Nats roll with veterans Starlin Castro, Howie Kendrick and Asdrubal Cabrera sharing at-bats between third and second. At least, that was the plan had the season begun on time. Depending on how live baseball in the pipeline shakes out, the Nats might prefer Kieboom break camp with the team just to ensure he’s continuing his development via live baseball. With a potential DH in play, there may even be enough at-bats for the Nats to accommodate playing time for Kieboom and their veteran triumvirate.
Also like Riley, Kieboom wasn’t overly impressive in his first taste of big-league action. Apologists have plenty of cause to support Kieboom even after hitting just .128/.209/.282 over an 11 game stint early in the year (which included 4 errors at shortstop). Reason being: he wasn’t ready. Kieboom’s April promotion was a case of injury-depleted desperation. The Nats were in a bind with Trea Turner on the shelf. Wilmer Difo wasn’t getting the job done as Turner’s understudy, and the Nats were off to a slow start (11-12 at the time of his debut).
The small sample hasn’t done much to lessen the optimism over Kieboom’s potential, especially after he raked for a line of .303/.409/.493 for Triple-A Fresno. The shortstop-by-nature has a long-term future at third or second in Washington, though the suggestion has been that his power will play enough to handle third, and the Nats’ other top young bat has spent most of his career at second (Luis Garcia).
Riley is about a half-season ahead of Keiboom’s trajectory, giving us more familiarity with his game at the pro level. But for comparison’s sake, Riley hit .293/.366/.626 in 44 games at Triple-A in 2019. They’re both former first-rounders (Riley #41 overall in 2015, Kieboom #28 overall in 2016), but their draft status won’t help as each looks to fill the shoes of franchise legends.
And yet, they’re not the same. Riley is a hulking light-breaker who’s defensively playing up to stick at third base. His frame is redolent of a young Ryan Zimmerman before Mr. Nat made the move across the diamond to first. Kieboom’s not a small man himself (6’2″, 190 lbs), but some scouts thought he could stick at shortstop, and he brings a contact-oriented approach. He can stroke it to all fields with potential plus power and a track record of taking walks and putting the ball in play. They’re different molds as far as third baseman go, but neither has much leeway as they try to establish themselves in the majors. Not with both the Braves and Nationals looking to contend in a season that could be as short as 50-some games.
Whenever they claim regular roles, Riley and Keiboom will be two exciting young talents to track in the NL East. The Phillies’ Alec Bohm may very well throw his hat into this ring in the very near future as well (feel free to make your case for Bohm in the comments). Bohm is another former first-rounder (third overall in 2018), but he’s spent less time in the minors and is actually older than both Riley and Kieboom. Team conditions aside, let’s say you’ve got a hole at third base and the right to poach one third base prospect. Who do you want? (link to poll for Trade Rumors mobile app users).

How Nats Could Continue Benefiting From Jordan Zimmermann’s Exit
It’s true that right-hander Jordan Zimmermann has fallen on hard times over the past few years, but it’s indisputable that he’s one of the top starters the Nationals have had since they moved from Montreal to Washington in advance of the 2005 season. A second-round pick two years later, Zimmermann debuted in Washington in 2009, but it took him until 2011 to break out. From then through 2015, Zimmermann logged five straight seasons of 3.0-plus fWAR, went to two All-Star Games, and posted a stingy 3.14 ERA/3.30 FIP with 7.26 K/9 against just 1.69 BB/9 in 971 2/3 innings. In yet another impressive accomplishment, Zimmermann threw the first no-hitter in Nationals history in 2014 (video here).
The year in which Zimmermann fired a no-no against the Marlins proved to be his penultimate season in a Nats uniform. He went on to parlay his success in D.C. into an expensive contract with the Tigers, who signed him for five years and $110MM before 2016. The Nationals haven’t missed him, though, while the Tigers surely wish they wouldn’t have taken such a big-money gamble. Zimmermann has never recorded an ERA below the mid-4.00s in a season in Detroit, where he has registered an overall 5.61 ERA/4.86 FIP through 508 2/3 frames in the first four years of his deal.
Considering how he has performed of late, not only does it look fortunate for the Nationals that they let Zimmermann walk, but doing so has a chance to continue benefiting the franchise for years to come. You see, by issuing Zimmermann a qualifying offer that he rejected, the Nationals received a high pick (No. 28) as compensation in the 2016 draft. They used that selection on on a Georgia-based high school shortstop named Carter Kieboom. There’s now a chance Kieboom will turn into a long-term linchpin at third base as the departed Anthony Rendon‘s successor.
Now 22 years old, Kieboom has typically produced quality numbers in the minors – he batted .303/.409/.493 with 16 home runs in 494 plate appearances in his Triple-A debut in 2019 – and has rated among the majors’ highest-regarded prospects over the past couple seasons. In its most recent rankings, Baseball America (subscription link) placed Kieboom No. 1 in Washington’s system and 15th in all of baseball, calling him a potential “weapon” at the top of a lineup in MLB.
Kieboom was anything but a weapon during his first taste of MLB action last season, when he hit .128/.209/.282 in parts of April and May, but his woes only came over a 43-PA, 11-game sample size. The Nationals probably aren’t worried, though it remains to be seen how much of an impact he’ll make this season (let’s say one even happens). Kieboom hardly stood out in spring training, though you can take exhibition results with a grain of salt. Still, if the Nats don’t think Kieboom’s quite ready, they can plug Asdrubal Cabrera and perhaps Howie Kendrick in at the hot corner. Doing so likely wouldn’t stop the Nationals from believing Kieboom could be part of the solution over the long haul, and if he does eventually live up to the hype, it’ll be an added bonus for moving on from Zimmermann.
